Initially excited about the size, response to the application, and especially for the real-time status indication (open/close) and battery. And somewhere here the nice things end. Just 1 week ago I set them all up with the sonoff zigbee pro hub at the cottage, in order to be used in a home alarm scenario with the ewelink application. Initially, I have them all together on a desk to check their behavior before placing them in their final position. Last night suddenly, and while the hub is online, all sensors went offline!!! Unfortunately, after the holiday, I read in various forums that it has happened to other users as well. This makes the whole sonoff package completely unreliable, and if there is no firmware update to fix the problem, it is the most useless purchase I have ever made!!!
I have bought 3 sensors and they work flawlessly. I had a problem with the battery that lasted a little, but I put a Varta prof. and I have been without any problem for 1 month+. I will buy more to fill the house, and I will add that the Zigbee hub is needed for the traps to work
Connected via Sonoff's Zigbee bridge. Minimal battery consumption, fast response in opening and closing. The only downside is that you cannot use it for scenarios and automations through Google Home and the eWelink application
Good product at the right price. It can only be connected through the Sonoff ZBBridge device. It has reliability in notifications and can participate in many scenarios with other Sonoff devices.
Excellent value for money, I have about 4 of them for approximately 2 weeks combined with the aeotec hub (SmartThings), even at a relatively short distance (~5 meters maximum distance with 1 wall in between) and so far they don't seem to have any issues, no disconnections or false alarms, and the battery seems to be fine - it hasn't dropped below 100%.
It actually does what it says.
I've had it for 1 month and the battery is still full!
Immediate response, notifications come instantly and commands from Alexa are executed smoothly and quickly!
Connection with ConBee II Zigbee stick to Home Assistant. No problem so far.
Value for money. Especially now that other well-known brands have exceeded 20 euros
It works with hubitat elevation. Like all ZigBee devices, it requires repeaters. I have had them installed for 11 months and they are all at around 70%. It provides quick feedback to the hub.
Connected seamlessly with the Sonoff ZB Bridge and so far it works perfectly without any disconnections!!!
Update: 19/04/2023
Unfortunately, after almost 1 year of use, I am extremely disappointed with the product!! The battery that came with the sensor lasted for almost 3 months.. All good until this point. However, any battery of any brand that I subsequently installed did not work for more than 1 to 2 days, rendering the product essentially useless. I couldn't find online the cause of the problem and a possible solution... Complete disappointment!! I am changing my rating to 1 star, at best!!
First of all, excited, then disappointed after a few days!
Three out of the six sensors that I bought keep disconnecting even though they are within a distance of 5-10 meters from the ZigBee Hub.
Bad product, I have bought two. One of them never worked. The money was refunded immediately. In conclusion, I do not recommend it. The negative is that I have purchased the Sonoff Hub and I do not know if I have any other option.
