Floats in ya pool and tells yer the temperatures!
CamelCamelCamel.
had same problem but realised it drains exponentially with distance.
ie 15-20m about 2-3 weeks
now its 5m away and last few months easy
another is used for my pond (turle/fish) and 1m away last 6 months+
Okay so the one you have has that little receiver that you can mount in the house or out on the deck which shows the temperature for the pool water?
Does it also show temperature of where the receiver is located hence the two temps on the image?
Seems a pretty good idea apart from the batteries not lasting.
Mine lasted a fair while for the first two years, now its basically dead, works for a short while then just nothing, not sure if suddenly draining quickly or just broken or both.
Just paid $32 for one of these after last one died after about 2 years.
IBS-P01B sounds like an old model ?
The one I got was IBS-P01R
EDIT: ok found this
What are the Differences for 2 Types of Swimming Pool Thermometer?
-IBS-P01B Bluetooth-Compatible Version—-Support smart phone monitoring via Bluetooth. No indoor unit, only the Pool Thermometer, view temperature data through the phone, and support the recording function.
-IBS-P01R Wireless Version : Indoor unit + Outdoor unit, Can be viewed through the indoor unit. Transmission Frequency: 433Mhz.
-With the use of wifi gateway, both of the thermometers can be connected via 2.4GHz WIFI.
IBS-P01R is 433MHz, requires a custom receiver, doesn't integrate to anything (without some in-depth hackery)
Has a good battery life
IBS-P01B is Bluetooth, integrates well, battery life is ok if Bluetooth receiver isn't too far away
So I just bought this. Is the Bluetooth receiver not just your phone? Would love an external Bluetooth receiver to monitor all the time via home assistant though
Buy USB bluetooth dongle.
Buy 5+ meter long USB extension lead.
install dongle closer to pool….Voila
Temp down to -40°c. How would you change the batteries once it got down to those temps?
Once the block of ice in which it’s embedded has thawed, extract and replace as normal
Thanks OP, for the price I will try this with Home Assistant
I had one of these and found that it went through a pair of AAA batteries every 4-6 days, rechargeable which seem to have a lower voltage than disposables would be lucky to last a day :(
