Works well, no problems

Nice little sensor for inside the house. I've been using it for a few weeks connected to Home Assistant Z2MQTT without any problem.

Works well with smartthings. We use it in the bathroom to trigger the extractor fan to come on when the humidity rises during/after a shower. No problems with it so far!

The Thirdreality Temperature and Humidity Sensor Lite came installed with firmware version: v1.00.47. It was paired with a FRITZ!Smart Gateway with OS 08.24. Pairing was successful. Whilst there is some indication to support the observations that the temperature feedback algorithm might be a bit coarse, it was not an issue for my more basic requirements. The unit seems solid and well-built. It uses AAA batteries, which is a clear plus point.

Much better than the SONOFF series.

As other reviewers have reported, there's a critical issue with the precision of the temperature data these devices are reporting - From the product description: > this device delivers precise and reliable data with a temperature accuracy of ±0.3°C However, even when configured with a minimum reporting change of 0.3C (rather than the default 1.0C), the temperatures reported only appear to change with a precision of ~1.0C, with what looks like random jitter around each degree. My device is running the latest available firmware from Third Reality - 1.00.47.

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.

Facile à appairer avec Zigbee2MQTT dans Home Assistant, connexion stable

Messwerte sind super. Ich nutze das Gerät in Verbindung mit meiner home assistant Installation als feuchtigkeitsmessgerät und temperaturmessgerät. Es liest sich sehr einfach einbinden und funktioniert seitdem ohne Probleme. Batterien schalten auch lange zu halten

Ottimo prodotto, l'ho comprato per sostituire un sensore xiaomi che si disconnetteva di continuo, il collegamento di questo è stabile e non ho mai avuto disconnessioni. Prodotto altamente consigliato.

Cumple las expectativas

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.
