I wish that Aqara made a temperature monitoring device with a remote (type K TC or RTD) probe. Power by either mains, Low voltage AC/DC, or even USB, but NOT battery powered. Use a standard Mini Thermocouple input or RTD but do not hard wire the probe to give the user flexibility in selecting the appropriate probe for their application. To save bandwith, periodically transmit the temperature but also transmit whenever the temperature changes by a specified amount, e.g., 1 degree F.
If it had more than one channel it would be fantastic.
I need this to measure several places in a geothermal hydronic radiant heat system. But can imagine it would also be useful for solar water heaters, outdoor air temperature monitoring, aquarium / terrarium monitoring, etc.
If you tinker you might be able to hack apart a T1 Temp sensor to do all of this. It’s pretty niche so I doubt that Aqara will devote the engineering to a standalone product unfortunately. Hardwiring one would effictively be one of the easier parts in wiring in a power plug and feeding it with what the coin cell battery outputs from an external power source. Same thing would need to be done with the thermocouple, I don’t know what is currently being used for thermostat readings but you might be able to interrupt/remove the on board and wire in your Type J female plug to the circuit board.
Honestly though, doing all of this with an ESP32 would work better.
Hello, I think a remote thermometer won’t work with the Aqara sensor, there’s a digital sensor. Here I described how I solved the problem for myself. Is there a thermometer direct for a heating pipe - #12 by gafich10
