Best Smart Home Temperature Sensors for Home Assistant

[@nbessell]

I have a couple of the older Sonoff SNZB-02 sensors, but my preference are the Govee Bluetooth sensors H5075 or H5102. They also run on AA or AAA batteries. With a couple of ESP32 BT proxies around the house, the data is easily fed into HA.

Cool, thanks for sharing that!

You forgot 433MHz wireless. It's my favorite, for range, cost of sensors, and its ease in passing through barriers that attenuate the 900MHz and 2.4GHz signals you tested. I'm running LaCrosse brand outdoor sensors. Their range is fantastic and they're US$15 every day at a local big box hardware store. And they're specifically made to be outside.

Very cool, thanks for sharing!

Hope this doesn't come across too negatively, but the reliance on uncalibrated/potentially-unreliable baseline measurements makes me question the validity and value of the results. I would like to have seen something like a Thermoworks RH Spot or Hygrobug used that are both fairly affordable and professionally calibrated rather than an off-the-shelf cooking thermometer, et al. That said, I do appreciate the feature set breakdown and pricepoint comparison, fascinating to see that sometimes the more expensive options seem to be outliers relative to the control, would just like to have a better established baseline to better to able to evaluate the results. My critiques aside, thanks for all the great content you put out!

Thanks for the feedback and for watching!

Nice tests. I'm in the market for a set of these; deciding between zwave or zigbee.

[@michaelsleen]

If you already have a Zigbee adapter, I recommend one of the SONOFF sensors. If you already have a Z-Wave adapter, then I recommend the Zooz sensor. If you have both Zigbee and Z-Wave adapters, the SONOFF sensors offer a good value.

Thanks for reviewing so many different sensors, that's very helpful. I have a question about your terminology. For the two Sonoff sensors you say they have no "temperature offset" capability, but in the screen the Calibration text says "Yes". Is calibration different from offset? Also, for the Zooz sensor the screen says "Calibration: Yes" but you dont audibly say anything about adjusting the reading.

[@michaelsleen]

You can calibrate the temperature of the SONOFF sensors in Zigbee2MQTT. Zooz provides documentation on their website. Apologies for any confusion, and thanks for watching!

I was surprised that the Aqara temperature and humidity sensors weren't on the list. Any reason why I should avoid them? I just bought a bunch on Amazon, but I think I'm still within the return window. Thanks for the great video.

[@michaelsleen]

I have a few Aqara devices, but not the temperature and humidity sensors. No reason to return them, but I have had mixed experience with Aqara products.
