This is the way.
Alot of things, I use it for wifi relays (remotely controls things via wifi) and bluetooth bridges/extender (when you bluetooth device wont reach eg door locks etc Via Homeassistant.
This is want I want to use it for. Extend my Bluetooth headset. So I can make a coffee at the other end of th3 house while in a meeting
Ty for the use case
Yeah, it's not going to work to extend your bluetooth headset. It's more to act as a bluetooth gateway to transmit back to home assistant or similar
I use it for wifi relays
For simple tasks like that, the ESP8266 is considerably cheaper, about $2 at AliExpress. You can also buy them with a relay attached, for only a little more.
The ESP8266 isn't as versatile as the ESP32, but the extra features of the ESP32 frequently aren't needed. Check out the ESP8266 with LUA (a scripting language) for the most versatile version of the ESP8266.
Yep, I have about 20 or so ESPs laying around. Rarely are the 32s required, 8266s are plenty good enough for most use cases.
Sorry if people with hobbies offend you.
Definitely more productive than what you do
I mostly use them to help fill my box of unfinished projects.
I used one (from AliEpress) to build one of these fermentation trackers.
https://github.com/kbaggen/SPINDELMATENote on AliExpress you can get the same board delivered for less than half this price!
$4.66 incl GST

The only benefit of the Amazon seller would be speed of shipping, if the stock is indeed local.Do you use the rapt or built an ispindle? Im still not sold on them so far. The tilt looked good but was too expensive for me
RAPT Pill
I looked at building an iSpindel, but just the hassle of not having to source a suitable container was worth the cost IMHO.
Of all the specialty brewing gear, the RAPT Pill is a bargain.One issue, can't get the calibration right (although only done it with a single point calibration in Water). Probably need to "waste" some wort to calibrate it properly I guess.
Here is the data coming off the RAPT/Bubble logger for the current brew.
https://bubble-logger.com/line-chart/share.php?Brew_no_id=54…If you're not keen on spending $50 on a Pill, the Bubble Logger (less than $10 parts, assuming you have a spare USB cable and charger) alone is good for tracking the brew progress.
@ESEMCE: I've never used one of these things so forgive me if this is a dumb question, but why would you need to use wort to do the calibration? Isn't the goal just to have liquids with different SGs to match up the reading between a traditional glass hydrometer and the device? Couldn't you do that with a bucket of water and just gradually adding different amounts of salt?
@pscac001: Yeah also an option, but easier to just do it with wort rather than fart-arse around for 20 minutes matching the SG.
If you were super careful with cleanliness you could probably still ferment the wort used for the calibration.It seems to still work fine, it's just that the graphs show a final SG of <1000 which just looks wrong, which is probably actually my main reason for not bothering.
Ah bugger, I pulled that link from my purchase history and must've grabbed the wrong one.
Here's the correct link, A$7.38 incl GST@bio: The link and price (at least for my login, YMMV) is correct, I don't think you can link directly to the item (the URL doesn't change when you change items anyway). It's the second last option, shows as ESP-32 30P.
Thanks for sharing. The fermentation sensors are super cool. I see yet another project in my future.
microcontroller with embedded wifi/BT. Can do a lot.
I just threw together a temp/humidity sensor deal that also calculates dew point with a spare nodemcu. Lives in the kitchen and outputs to a little screen so that I can get local readings. Next step is pushing that info to HomeAssistant when I get around to it.
I’ve got a few ESP32s and have been wanting to do exactly this!
Do you mind sharing some info/photos/links etc?
Cheers!
If you're looking at using them with Home Assistant, ESPHome is probably your best bet.
I was going to do this using a temp sensor and humidity sensor (bme 280) which seems to be the most accurate for the price but I destroyed it accidentally when soldering the pins on the wrong way then try to take them off and ended up ripping off the pads so currently in the unfinished pile of projects lmao
and I was going to use a small 1.9 inch oled or whatever to display the data
Sounds fine but I hate the thought of wasting a power socket for these things
Can power via USB from other devices such as TV, router, PC/Laptop etc. I had a temp/humidity one connected to my TV USB port to not waste a socket. Can also get double adapters etc with usb ports.
WLED controller!
Nerd stuff, basically.
e.g. I've an LED strip above my monitor driven by one of these (actually much older vers). It keeps tabs on my Plex server and lights up an LED-per-user if any of my mates play something with the colour telling me if they're having to transcode, are buffering etc. Of absolutely no use whatsoever but nice to see it light up every now and again as people use my stuff and was a nice little weekend nerd project. Only thing is I can't find the sketch any more so when this chip dies that project is gone :(
If you're referring to the ESP8266, you should be able to dump the binary to your computer using esptool. You won't be able to edit it as a sketch but you could at least keep your cool project ongoing if your esp ever dies or even share it around (assuming important details/credentials aren't hardcoded in) :)
Yeah, good idea. For some reason I never thought of that. Thanks for the idea, appreciate it.
that sounds really cool. No point in me doing that as I don't have any friends to light up my LEDs.
I just got Tautulli running on my Plex machine last week and man I wish I'd done it sooner - the stats are so cool!
I have like 2 users aside from me but I love being able to see how much theyre transcoding and what they watch etcYeah, IIRC I'm actually pulling from the Tautulli API rather than direct from Plex. If you're new to Tautullii, check out resources lke JBOPS on Github - the 'notification agent' functonality is very good.
TBH Tautulli and Plex Meta Manager (PMM) really elevate the Plex experience.
Wi-Fi + BT + BLE MCU module.
Ahh yes the good old ESP-WROOM-32, I know it well.
I have no idea but everyone is so excited, I now want to start and never finish an undefined project.
I grabbed one for that project, I never did manage to get it working with Powerpal. Unfortunately, not as simple as it sounded and the HomeAssistant "How-To" thread is sooo long was too hard to follow due to all the differing comments on how to achieve, I gave up after many wasted hours…hahaha.
Great devices though.
Yeh using mitm-proxy and getting all the credentials was not easy for a noob
I just did this recently and had issues until this post: https://community.home-assistant.io/t/powerpal-smart-energy-…
Followed those instructions and it worked. I think I had no data for a bit but just had to be patient.I considered that as well, but found it easier to build one using EPS32 and Photodiode module from scratch:
https://github.com/klaasnicolaas/home-assistant-glowIt works great with Home Assistant and cost me less than $9 delivered:
- ESP-32 30Pin $4.34
- LM393 Light Sensor Module $1.29It was actually closer to $6 since I had few other "Choice" items in my cart so shipping was free and it arrived within 12 days (even the non-choice Photo Diode).
I was considering this (and still might) but at this point don't want to fully replace the Powerpal device as it just works well and handy for Data exports. I like that it stores it's data onboard so should systems go offline e.g. a Power outage no data lost.
Thanks for the reminder though as excellent project for those that don't have a PP device or happy to swap out.
Other Interesting Power Meter option
I use the Powerpal Pro which has a built in 8266 (or maybe it is a 32, I can't remember).
Powerpal Pro?? Got a link
I don't. Got an email to sign up for the beta like a year ago. Not sure when they're going public with it.
@Tacooo: Yeah, if you have that they you get access the Encryption Keys and direct access to the data. Annoying that Powerpal just don't make it available on request. Would make it an amazing product then.
Also 2 for $19.38 from this seller (also fulfilled by Amazon) though if you're spending that much you'll be able to buy at least 3 from AliExpress and get free fast shipping.
Delivery on these shows as 2+ weeks for me…
I'd recommend some ESP32-C3's from Aliexpress instead since they have USB-C, the same delivery timeframe, and they're about $4 each delivered if you get a couple.
I'd really not recommend C3. It's a pointless bastard between ESP32 and ESP8266.
Get ESP32-S3 chips instead ($6-7 on Ali), unless you need to deploy a large number of them and you are very price sensitive. The S3 have the "AI" acceleration and can do on-chip speech recognition.☝️This is the way…
C3 has only a single core RISC-V at 160MHz - good as direct replacement for low end esp8266, better go with the more modern S3 dual core Xtensa LX7 up to 240MHz with AI acceleration.
ESP32-S3 is also the SoC that powers the new Arduino Nano ESP32, so you can expect the community support and projects available to go through the roof.
How can you "not recommend" C3 if you don't know what the project is?
The C3-mini is great for all sorts of little projects such as adding BLE access to a couple of sensors, or controls.
BTW, GP linked an S2, which lacks bluetooth.How can you "not recommend" C3 if you don't know what the project is?
Well, how can anyone recommend anything, especially the wildly unsuccessful C3, without knowing all the projects it cannot be used for?
As you did not actually expect any real answers, you can go ahead and argue with yourself about "How".
I'm using mine as a current sensor and wifi relay for my EV charger. I don't need anything fancy and paying $7 instead of $4 doesn't make sense for features I don't want.
Just a word of warning if you're doing anything Bluetooth related that the C3 and S3 chips are BLE only, no Bluetooth Classic (Which is what hobbyists are generally used to).
There are also a bunch of the ESP32 libs that are super buggy on these RISC chips
My preference has been towards the USB-C variants of the ESP32-WROOM from a local eBay seller
https://www.ebay.com.au/itm/155122288135 (cheaper in bulk too)I'm sure you could get cheaper from AliExpress but haven't had any issues with that seller and they are actually stocked in Australia so usually arrive within a week.
Way cheaper on ali, 15 day free delivery if you buy for $15 or more https://vi.aliexpress.com/w/wholesale-esp32s.html
No dealWouldn't the shipping be terrible because of Lunar New Year Break in China or has Ali gotten better even for the holiday seasons?
I am not gonna lie, they've gotten lot better so i wouldnt be surprised if the holiday do not add much time to shipping.
So it's $5.32 + $2.99 shipping + $0.82 tax = $9.02, not way cheaper unless you buy 3 of them, and you have to wait 15 days.
How reliable have you found Ali Express to be in general? Are there any pitfalls?
I bought a very similar board (D1 mini style) a couple of weeks ago from Aliexpress, delivered in 10days to Adelaide for about $3.50. I have used the same seller (Tenstar Robot Great Wall) for these for a number of years and have been fast and the products as expected.
If you get their 15 days delivery, i found them to be very reliable. I had one item that arrive late, but most came on time (and filled my auspost list with from ucl co ltd with their tracking)
One learning - always triple check the seller name and rating.
There seem to be pop-up sellers (quite possibly even bot set up) with shop names like Shop23356832 set up to either harvest data or make money by holding cash for a few weeks before you either make a claim for no delivery or (probably quite commonly) forget you even bought that dooverwhacky.We bought over 100 dev boards and sensors on Ali, only had one issue (a temperature relay was measuring really off values), but they refunded it.
Delivery these days is good again, comes in less than 2 weeks.The usual pain point we have is the lack of documentation for most sensors - sometimes even pinout is missing. We had a problem recently with an ultrasonic sensor, which was documented not to measure distances less than 20cm (fine for our use case), but it was not documented that it would return some random distance value if an object was within 20cm. Fun times. It's not Ali's fault though.
How reliable have you found Ali Express to be in general?
There are always shonks. On my very first order, I ordered a car radio, and received a hose clamp.
I took a photo, complained to AliExpress, and they refunded my money pretty quick.
Don't use AliExpress if you need to have something before a particular date, as shipping may be delayed, and you may not get what you ordered. But if you can tolerate the delay and the occasional wrong product, you can't beat them for price.
The other thing to be aware of, is that you have no idea if these are retail-quality items, or if someone dumpster-dived the rejects bin on rubbish-collection day, and sold those that seemed to work okay. You could easily be getting items that have failed quality control, so don't buy safety-related things from AliExpress.
I personally won't buy lithium-ion batteries or things containing lithium-ion batteries from AliExpress. Yes, there's less than 1% chance it will burst into flames while charging, but if it did, would you get it outside before it set fire to your house? It's very difficult to extinguish lithium-ion battery fires.
I disagree and have no issue recommending Aliexpress. I order from them all the time and have done so over the last few years. Never had an issue. Even the cheapie junk I ordered was fine but if crap and doesnt work, they refund without question. Perhaps you have been unlucky?
Just ensure you buy from reputable places with good feedback as one would like with Ebay etc. I try to chose places with the "Choice" label but not absolutely necessary.
Perhaps you have been unlucky?
Perhaps it depends on what you order. Try ordering Lightning cables and USB cables. Just like Amazon and eBay, I suspect the majority of the sellers on AliExpress are just resellers, they have no idea of the quality of what they are selling, or if their product is a counterfeit.
I've used multiple marketplaces in the past: EachBuyer, Meritline, BuyInCoins, Fasttech, Banggood, Gearbest, and more. All seem to have the same problem, they are just a conduit between you and the seller, and sometimes the seller doesn't even know that they're selling trash. Or so they say, when refunding. Some sellers remove bad items from their store after complaints, others don't.
Just ensure you buy from reputable places with good feedback
Now, I only buy from well-known "official stores" on AliExpress, and I've had good success with that, so I mostly agree with your statement. Still won't buy lithium-ion batteries though, because even Samsung and Apple have had fires caused by their batteries, so reputation is not necessarily a guarantee.
I bought one a few weeks ago after one of my nanoleaf essentials bulb had to be reset and then would no longer reconnect to HomeAssistant (no BT ports available or something).
HA has Bluetooth and it was working so I don't know what the issue was. Anyway I was able to re-pair the bulb to HA via Bluetooth with one of these and then re-add it to thread.These are way too slow to control lights though.
I fell like this is becoming HABargain… I'm not complaining (I'm into it) but there's been a few Home Assistant-related deals recently.
I've bought ESP dev boards from AliExpress in the past, they're usually a lot cheaper (but it takes forever to arrive, and sometimes by the time it does arrive I forgot what I was going to use it for)
bought 1 because it is cheap. i don't know what it does, but i will figure it out.
+1 for the attitude
You can set up one of these to semi-automatically jailbreak the PS4 (the jailbreak isn't persistent on many PS4s, so having a device that automatically handles it helps a lot)
Can highly recommend this project with it.
Makes it stupidly easy to configure and manage those devicesThe indentation/spacing of YAML is the bane of my existence, but for the flexibility it gives me with home automation it's a very small price to pay.
Any decent IDE supports yaml with no issues now - VS Code, Intellij Idea, you name it.
notepad++
sorry just had to name it.
Wait, you're telling me that you DON'T brute force your way through a Firefox text box??
I gotta keep up with the times!
Can be used for ESPresense in Home Assistant for presence detection. I place these around the house and they track my phone as a Bluetooth beacon. I use these in rooms where I'm stationary and motion sensors won't keep the lights on
Good video here https://youtu.be/p7C2QvmsM8M?si=SeOcUsOoAxSFUSIl
So happy to be surrounded by geeks!! 🤪
This isn't a particularly good deal IMO.
- It's a fairly old model of the ESP32
- It's several times the price of newer ESP32 models on Aliexpress
- It doesn't say if it has any extra RAM, so I guess it doesn't
- Have a look at, for eg, the Lolin S2 with 4MB of SPIRAMAgree. I got a Lolin for like around $5 if I remember correctly
Aliexpress has those for $4-$5 with a choice of MicroUSB and USB-C connectors with free shipping over $15 (10-12 days delivery)
Unless you really need next-day shipping in metro for whatever reason, this isn't a deal.
Aliexpress has then for cheaper and with different options of connectors and specs
