    The app reviews are very underwhelming. As the product is only as good as its software, these are quite salient.

    For those of you who don't know what this is (which I imagine is most), its a combination temperature/humidity recorder. It can record up to a months worth of readings, and then transfer them to your phone when you connect it via bluetooth. It allows you to see the temperature/humidity variations as a graph, and see at a glance any troublesome indications.

    People use them in refrigerators - you could see what temperature the vegetable drawer is. Did you know that different vegetables have different temp/humidity requirements for optimum storage?

    Or you could monitor humidity inside your room at night, to see if the cold weather is giving you a dry throat in the morning, and whether you need to buy a humidifier.

    It has lots of applications.
    I'm going to get one just to play around with. On paper the specs are quite good, so its just the app thats a gamble, but at this price (its really cheap for aus stock) I think its worth a go.

      FWIW I use https://www.mysensors.org/ to create a gateway and mesh of sensors that feed temp and humidity etc back to my home assistant (https://www.home-assistant.io/). Each node costs maybe $5 (and can have multiple sensors attached), and the gateway itself (which can also have sensors) is about $10. A ds18b20 temperature sensor that is protected by a stainless steel waterproof shield is about $1.50 and perfect for either fridge or freezer. Although it is more geeky, the advantage is I get alerts if there is something wrong with the fridge temperature (rather than finding out after the fact, with no need to remember to synch with a bluetooth sensor), and it's a lot cheaper…. let's see, currently the freezer is at -18.5 and the fridge is 2.6 so all good. It's 13.5 outside, but a comfy 22.3 in the master bedroom, 33% humidity which is maybe a little dry but not too bad.

      Another option would be the Xiaomi "Smart Temperature & Humidity Sensor" - the one with the lcd display. It also uses bluetooth and can use a gateway…. or can use the sensor without a screen that uses zigbee.

      Not saying the Inkbird is not good, just noting that there are a number of options out there for around the same price, or possibly cheaper. :-)

        Boy, do I wish I was smart enough to do something like that. I'd need to use all three of my brain cells to put together the system you've got, and right now two of them are busy thinking about pijammas.

        What hardware are you using to collect the data with?
        Arduino, rasberry pi?

        • I have home assistant running on a raspberry pi. With the mysensor stuff, my gateway is using a wemos d1 r2 (ESP8266) as it includes wifi, more memory, a faster processor, and is cheaper than an arduino (but a bit trickier to setup simply because fewer people use them so there's less help). For the sensors, I use arduino pro minis which require a bit of soldering, but are stupid cheap - but standard arduinos could be used there. If you just use arduinos, there's lot's of tutorials out there to go step by step and no soldering required. Think doing a lego set, but with some cables and very basic programming.

          Most of my brain cells have been wiped out by alcohol, but I reckon most people could do it. :-)

          • @PlasticSpaceman: Your setup seems like exactly what I want to do. Currently have a pi zero to monitor my aquarium temperature but it's not the best system and isn't as stable as I would like. Also would like to create a sort of mesh to optimise my heating/cooling/ dehumidifying needs. Making this comment to remember who to ask if I ever get around to putting this together.

              @EBC: FWIW There's also NodeMCU (https://youtu.be/jpjfVc-9IrQ), but I haven't tried that mainly because I wanted to be able to have battery powered sensors and the ESP8266 sensors use wifi which drains batteries too quickly.

          • @PlasticSpaceman: I think you underestimate yourself my friend, as many smart people are often want to do. While the actual act of buying a sensor, plugging it into a board, and following some tutorial to get it all working together are simple tasks individually, to get to that point requires a quite a few knowledge and skill dependencies to be attained.

            I'm getting there slowly, but I still have a way to go yet before I'm at 'that level'. When I am though.. whoo! The world better watch out! I got some big ideas.

            Most of my brain cells have been wiped out by alcohol, but I reckon most people could do it. :-)

            This might have given me a boost, had my brain cells not also been wiped out by alcohol.
            Eh, no real loss. There was nothing much of value in those sectors anyway. Just snippets of old simpsons episodes and memories of eating potato chips.

    …"Used for Brewing Meat/Plant/Cigar Storage" :D

    • Gotta loved brewed meat.

      • Steak beer, there's gotta be a market for it.

  • Any chance of a deal on he standard IBS-TH1 please
    I've got the mini but using it in the fridge kills the battery life

    • Hi,low temp and high humidity has bad effect on battery.
      If you want to use it in fridge ,i suggest IBS-TH1 or IBS-TH1 plus as they have external probes
      Here is the link:https://www.ebay.com.au/itm/222711310923
      Please make offer at $35 and leave a note about OZ,then it will be accepted.
      Thank you

  • Are these weatherproof. Eg can be used outdoors?

    • Hi,sorry it's not waterproof.If you want to use it outdoor?
      How about ITH-20R ?It includes Receiver1 and Transmitter1.
      Transmitter is waterproof and you can use it outdoors
      Here is the link:

      • Thank you. But I am looking for an outdoor weather data logger that will be out of range and only downloadable by bluetooth every few days.

        • If it's really out in the sticks, maybe a weather station that can send you the info via 4g eg https://openweatherstation.com/ows/index.php. Some assembly is required, though. :-)

          Otherwise there are things like https://www.maximintegrated.com/en/products/ibutton/data-log…, or https://www.instrumentchoice.com.au/instrument-choice/data-l…, but they are not cheap.

          Personally I'd find a data logger that runs off batteries & that has external sensors, and work out how to put the logger in a water/dust resistant box, and then put that in a protected area as much as possible. The sensors can run via cables from the box - just make sure that the hole the cables come out from the box is properly sealed. If it's just temperature you want to monitor, a waterproof ds18b20 sensor is perfect, and plenty of projects out there showing how to use that to log data using the likes of an arduino.

  • Bought 2 a few months ago to use on my humidors (cigars) and they are horribly inaccurate!
    Just do the good old water and salt test or buy a boveda 75% humidity pack and you'll see what I mean.
    Contacted Inkbird's support and never heard back…

    DON'T buy this if you're concerned about accuracy.
    If you're not, you shouldn't be buying hygrometers anyway :P

    • Hi,
      Could you please PM me your ebay name?
      So that i could check your order.
      Don't worry,i will help you solve the problem.
      If it's faulty,i will send you new replacement.
      Thank you

      • I bought them both off of Amazon.
        Happy to send you the Amazon order again (even though I've already contacted Inkbird's support via e-mail).

        Thanks

        • Hi,please let me know your Amazon order ID?
          So that i could ask my colleague to contact you.
          By the way,you are from AU,right?
          Thank you
