SONOFF

Excellent! I use one in the sauna because it's one of the few that works at 100C (the display is outside the sauna room, with the sensor going through the wall). I use the other one outside for my childs paddling pool water. I connect them via Zigbee to my Home Assistant. The sensor is very accurate I even measured my body temperature under the tongue with it, and it was spot on :D

It seems good but I hope I never have to see if it really works or not :)

Very good for what I need. I use it to check the temperature in my Aquarium with alert that tells me if the temperature is too high and I use also for an old fridge to check the temperature. The only "defect" I find on this product is that the probe is not replaceable; it should be better have it with a 3.5 jack.

Deployed two smart plugs to improve the quality of my zigbee mesh in a large, two storey brick and concrete house. Mesh works fine and stable now. As a bonus I use the smart plug to control lights from my Home Assistant. The power metering function is really nice, but I have not used it in a major application.

We live in a fairly humid coastal area. I deployed four of these devices in and outside my house to monitor temperature and humidity, and if necessary activate one of my Meaco dehumidifiers. Works well, it integrated easily into my Home Assistant network. The nice thing about these devices is that I can read values on the display, no need to open HA. Very happy so far.

Used to monitor outside temperature with also quick reading for people.
Quick connected to Home Assistant using z2m.
Everything fine until now ...

Used to monitor pool temperature.
Quick connected to Home Assistant using z2m.

Used this sensor to monitor pool temperature. Successfully connected it to Home Assistant using z2m.
2 weeks after installation - everything works fine

This product has a really nice design and features. If you could add a meter to it, it would be even better. The buildup material is very nice, and the features are great. Could you also add Matter protocol to the Apple HomeKit to have more integration?

... The best way to start your ZigBee journey in home assistant.

This latest purchase of 6 smart switches is my second order. The first batch has worked well for over a year now without a single problem. I am in Australia and this means the mounting plate / back boxes are not the same as the UK /EU standard but can be obtained online. Highly recommended. Hey Sonoff, how about making an Australian version.

sensore molto utile e indispensabile per chi sempre fuori casa non vuole ritrovarsi sorprese al rientro. Combinato con una valvola idrico smart la morte sua.

Il dispositivo fantastico, nonostante le sue dimensioni svolge il lavoro egregiamente

Prodotto compatto e rilevazione temperatura e umidit molto precise.

I have 4 of them in my house and they work without fail
