| Zigbee | Works Local | Worked in a freezer for months; condensation killed it, use a bagSaved copyI had a Sonoff SNZB-02 in a freezer for several months to prove to my wife the freezer (-4 degF) was not randomly defrosting. It worked fine until I took it out and condensation killed it. I’ve since learn had I put it in a ziplock bag it would have been fine.

| Zigbee | Works Local | Rock solid, about 1 degree offSaved copyMy sonoff SnZB-02 have been rock solid for me. They aren’t 100% accurate by usually off by 1 degree Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23. | Reddit comment · 2024-11 | |
| Not named | Partly works Local | Drops off periodically; only re-pairing recovers itSaved copyI get the same issues (in using SNZB-02 all over the house) and from time to time it's just dropping and the only way I can get it "back" is to remove it from HS and "repier" it Excerpt saved from the Arctic Shift Reddit archive on 2026-10-23. | Reddit comment · 2021-03 | |
| Zigbee | Not working Local | OP found them constantly dropping; SNZB-02D with Sonoff-P dongle stable for another userSaved copyBest temperature sensors?. Last year I tried to play around with HA and somfy zigbee SNZB-02 temperature/humidity sensors but I gave up as they were constantly dropping. I’m now reevaluating this to manage heating more precisely in my new house. What are the recommended options? We have 3 rooms where I’d like to automate heating, over 2 floors.

Once Home Assistant’s HomeKit Bridge shares it, this device reaches Apple Home as a HomeKit accessory behind your Home Assistant bridge, so ReReHome shows and controls it like any other.
