Wired Temperature Sensor Recommendations?

[meager quarry]

Looking for a reliable wired z-wave/zigbee temperature sensor that updates every 30s. Any recommendations?

most zigbee temp sensors are going to be battery powered due to their nature. your more likely to see externally powered on the wifi side of thiings. although you can probably find something with a usb connector on or even maybe modify one to use a dc supply.

Makes sense. Any recommendations on the wifi/usb connetor front?

[jolly wolf]

whats the use case? are you just looking at room temps?

[meager quarry]

Yeah, I'm looking for a room temp to turn on my window AC when it goes above a certain temperature

My AC unit has this functionality, but there's a huge delay. It'll go from 70f to 85f before it kicks in.

there are multi sensors like THIS and THIS

there are dedicated sensors with a probe like THIS
or you could build your own with an esp32 and a DS18B20

if you can have an excuse to get some multisensors you can do other cool things too 😛

I'm using the thirdreality zigbee temperature and humidity sensors, and their update time seems to be dynamic - in my logs, i have see them reporting about every 1-2 minutes when the temperature is changing quickly. That has been fast enough for me for controlling my AC system.

(in my case, i have a portable AC unit with an integration that lets me control the thermostat from HA, so I've built an automation that lets me use the zigbee temperature sensor effectively as a "remote" sensor for the AC unit by calculating an offset to apply to the AC unit's own thermostat)
