Voilà : il est possible de proposer un article sans fioritures, à un prix correct, et qui s'intègre dans le réseau ZigBee facilement.L'étalonnage d'usine est très correct, ce qui est également très appréciable.

Werkt perfect met ZHA in Home Assistant. Batterij gaat lang mee.

My use-case for this sensor is to monitor the temperature inside my freezer and my fridge to provide early alerts if either fails and the temperature starts to rise. I use this with my Hubitat home hub. I also have one sealed in a waterproof floating container in my hot tub to tell me if my heater has failed (bad scenario in the winter).Overall I am super happy. I had tried other temp sensors from brands like Aqara and SonOff. Those continued to fail in these applications because of the smaller button cell batteries. Even the larger 2450’s didn’t work in the freezer as they don’t like the extreme cold. These ThirdReality sensors with two AAA batteries work super well with no battery issues and maintain a strong signal. I had similar problems with the other brands with intermittent connection fails for the hot tub application, and this sensor works much better with zero issues.Also happy with solid build quality and easy pairing. I also own ThirdReality vibration sensors and those are equally great.

I have a Home Assistant server running at my house that controls a variety of devices and services (e.g. lights, switches, valves, etc.) and wanted to add temperature sensing.My old sensors from a different brand used Bluetooth Low-Energy, but their short-range signal couldn't reach the server (I had to use their phone app, which was not ideal).I had previously installed a Zigbee mesh network for several devices, and adding these Zigbee sensors to that network was simple: tell the Zigbee coordinator to look for new devices, insert the batteries into the sensors (or push and hold the button in the sensor for 5 seconds to enter pairing mode), wait 30 seconds, and they're good to go. I use Zigbee Home Automation (ZHA) and it got them set perfectly.The measurements are accurate (they match reality, as determined by other sensors I've previously calibrated) and precise/consistent (the Third Reality sensors all agreed with each other within the specified accuracy).For testing purposes, I moved several of the sensors around to different areas of the house and after a few hours they realized that there was a closer Zigbee router with stronger signal and automatically switched to connect to that, better signal. Certain other brands of sensors like "lock on" to a single router and if that router ever goes offline or they lose signal from it they never try to find another router on the network. That's not an issue with these sensors.Pros:- Simple: there's one button to put the sensor in pairing mode, and an LED that flashes to indicate when it's in pairing mode.- Checks for better signal/routers and will switch as needed. (That is, it's a good member of the mesh network.)- Accurate temperature and humidity readings.- Reliable data transmission. With the exception of the few times I rebooted the server or disconnected the Zigbee coordinator for testing purposes, the data from the sensors has been reliably sent to the server without issue. Several sensors were within a few feet of a WiFi hotspot (WiFi can sometimes cause interference with Zigbee since they share the 2.4 GHz band) and worked without any problems.- Use standard AA batteries rather than costly coin cells.- In addition to sending temperature and humidity data, they also send their battery charge level. Setting up an alert in Home Assistant so one knows when to change the batteries is recommended.- Very power efficient. Two AAA batteries should give years of service.Cons:- No option to calibrate the sensor. (While the sensors on mine are accurate, it would be nice to have an option to send calibration commands to them to correct for any error.)- No loop or other means of mounting or hanging it somewhere. My Bluetooth-based sensors are hung from a short string in the air in their various locations so they only measure air temperature and aren't influenced by sitting on a shelf or something. These sensors don't have a hole for threading a string or lanyard.

Used to replace my Sonoff sensors that occasionally drop offline and never reconnect.I already have a 3rd reality magnetic door sensor which has been installed for well over a year with no issues so hopefully these will be as good.

Bien reconnu par home assistant est surtout pour faire des scènes ou scénarios livré dans les temps enseigne sérieuse merci à eux.
