DRYFAL Wifi Tuya Smart Temperature and Humidity Sensor, Smart Hygrometer Thermometer for Alert, No Hub Required, Compatible with Alexa and Google Home, for Home, Baby, Garages, Intelligent Linkage

The product delivered was not as stated, although it looked very similar.First thing is batteries aren't supplied, but that's no biggie.Big issue is app compatibility. Advertised as Tuya/SmartLife/Alexa compatible but it's not. It uses CozyLife app which can't be used in SmartLife or Alexa automations.All I wanted to do was turn on/off a heater plug at set temperatures.

Very happy with the 4 I bought.Seem very accurate and pleased they show humidity too.Was very easy to set up and pair with Alexa.

I appreciate that the app and devices only likes to work on 2.4GHz but that shouldn't stop it finding devices on the network connected by 5GHz. In terms of Google compatibility I can only create a start event for humidity and not Temperature which was the point of getting the device. Thermometer is VERY SLOW to get a true reading. Pointless. Glad I only got the 1 to try out. Won't be getting another.UPDATE:They won't cover the cost of a return (which by law they should). I didn't have the energy to argue as I've not been well so I accepted their offer of a %50 refund if I kept it. Seriously dodgy seller. AVOID!!

Took about 10 days to deliver, this was advised at time of order, given delivery within a 4 day span and it arrived 1 day late. Instructions about the smallest I have ever seen, each page of a fold over pamphlet was 35mm by 55mm. I was unable to read one page even with a magnifying glass, resorted to photo with camera then enlarge.As for device, it is readable via Amazon but I have not been able to make it work with any other devices via an Amazon routine. As it is wifi and runs on batteries it does NOT appear to be connected permanently, it updates every 10 minutes (I think) so you will not get immediate changes shown.Slight problem, I already have a thermostat hub for central heating and a voice command gave me the temperature, now same voice command gives me average between the two, this makes voice control of central heating a wee bit awkward. Just need to alter voice command slightly so no great issue.Whilst I was expecting a bit more integration with Alexa I am actually quite happy with the product.

I feel these are great little sensors. Not expensive so you can have multiple around the house. Easy to add to the Tuya app. This part works better if you connect to your 2.4ghz WiFi on your phone and enable location and nearby devices.It is quite a small discreet device that can me mounted on a flat surface with the double sided sticky pad supplied.There are plenty of parameters that you can change using the app such as polling frequency for the temp or humidity as well as the sensitivity.I wish they had more integration with Alexa so that you can create events based on temperature or humidity. This means that you could switch on a fan if it gets too hot or turn on or off a humidifier based on the rooms humidity. Creating routines in Alexa does not seem to show this device as a smart device that has events.If you want to do this then I had to do this in the automation section if the Tuya app. I am lucky as my smart plugs are all Tuya compatible.I have given this product five stars as I can get this to work in the scenario I wanted but wish I could have done it in the Alex app.

Shows -16C in the app when it is, in fact, nearer +10CNo use at all, really.

It was tricky to change router to 2.4 but once I did that it works like a dream. It runs my supply overheating fan when it's a set temp in the room and cooler than the internal room temp to cool my bedroom. Will be getting a few more.

This thing drinks battery power so I am always replacing batteries. It works when it feels like it and isnt very accurate. Bad product.
