Review: Great value and good looking product - Took two/ three goes to pair device but so far it working great, brilliant display with back ground light. Fitted 13 amp socket in my hot press so I could keep USB lead connected so I didn’t need to use just the battery & thus worry about having to charge. Got it connected to Alexa but waste of time as I was hoping that Alexa could advise on temperature reading, this option was not available so I don’t see what use Alexa is? I connected device to my existing smart home app and device worked first time. I now have smart switch on control of my hot water system and now temperature reading all from my mobile phone.
Review: If you want a smart thermometer then this is for you. - I'll start this review with a warning: I am a geek and don't apologise for that. We have recently moved house and have an air source heat pump and sometimes the hot water seems tepid instead of hot. I wanted some way to monitor the water temperature in the hot water tank 24/7 and this promised to do exactly that. The setup was easy: install an app, pair the device with your phone, connect to the home WiFi and it was working. I installed it in a stat pocket in the tank (designed for this exact purpose) and it all works. The probe goes into the pocket and the meter attaches to the tank magnetically. It has a very obvious and bright red display (no problem for me as my water tank is in the garage but if this were in my bedroom at night it would drive me mad). It all couples to the Tuya IoT platform so I can actually monitor it myself and control other parts of the system based on its output.

### ⭐⭐⭐⭐⭐ Clear, simple temperature sensor
*by B***D on 30 December 2024*

Needed a WiFi based sensor that didn't rely on batteries for a freezer temperature alarm. This has a good clear display and also works with Alexa. I already have a Tuya smart hub, so it installed easily. Could do with a longer power lead though.
