I am looking for a battery powered temperature sensor that I can set a polling time on as well as be able to on demand poll. I purchased a Aqara Temperature and Humidity Sensor but am now realizing that it sends an update when it notices a change. I want to be able to have it scan every 2 min, 5 min whatever or tell it to update on demand.
My central AC unit for some reason occasionally decides to circulate hot air when it kicks on. My guess is that it occasionally doesn’t turn the compressor on and so just circulates hot air, I should probably look at getting it replaced but am not at a spot right now where that is feasible. Either way I would like a sensor that I can stick in one of the vents and when it gets above a certain temperature it can alter me so I can shut off the AC for a little while which usually fixes the problem. I have HUSBZB-1 so the sensor can be Z-Wave of Zigbee. Any recommendations would be greatly appreciated.
I have to ask, why would you want another sensor? The Aqara sensors send their data with BluetoothLowEnergy, so battery life is normaly between eight to twelve months.
In your case I would stick the Aqara sensor where you want it to be, set it up over Zigbee, and write an automation, to react on temperature. Something like this:
- alias: Restart A/C
trigger:
- platform: numeric_state
entity_id: sensor.aqara_temperature
above: 29 #just an example in °C
condition:
conditions:
- condition: state
entity_id: sensor.my_ac
state: 'on'
action:
- service: service.turn_off_ac # don't know which component you use to control the a/c
entity_id: my_ac
- delay: 00:05:00 # minutes to wait
- service: service.turn_on_ac
entity_id: my_ac
The other way would be to use another temp value from the thermometer to restart again. Something like temp goes back under 25°C, then restart.
Imo the Aqara sensors are one of the best temp sensors out there. For that price you get a good quality, they are small and reliable. I wouldn’t know of a temp sensor, that is that cheap in combination with reliability.
