SONOFF

Gut!

Does its job nicely.

It literally installs in a minute, the system recognizes it immediately, and it's easy to program. It's THE definitive solution for managing, in my case, my home's roller shutters. Instant automation and, needless to say, the quality is Sonoff.

Really impressed with this device for the price point. I've tried a few different leak sensors and these are just so simple to use, and the materials used are higher quality than the price would indicate. The plastics are almost "premium" quality. Very nicely manufactured and the surface finish is fantastic. The seal around the battery compartment is excellent quality silicon seal. It would keep the IP Rating for the long term. Pairing to Home Assistant using a SkyConnect dongle (SiLabs chipset) is perfect and worked first time with no issues. Detection speed is instant. The extension cables allowing multiple cables to be connected in line adds to the versatility by allowing multiple detection points on one sensor. Only one thing to note that is not 100% clear in the advertising. You need a minimum of two cables to get an extension point as the first one has to connect to the detector itself (means the detector no longer can detect water leaks with contacts facing down, but it could still detect drips. You need the second extension cable to act as that first detection point, as the extension cable is the two contacts, a hardwired interconnect cable and a connection socket on the probe point. That first cable connects to the detector, second cable will contain your first remote probe, from then on you can adda few if needed. I do have one sensor with 2 extension points (3 cables) to monitor a larger area with one sensor. It works out a little cheaper, and obviously uses one battery, but not a lot cheaper over using two actual leak sensors.

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.
