Water tank level monitor
After helpful support from seller, I bought this product to use as a monitor for my water tank level. The tank provides all water to my property but is located about 50m away in a hard to access location. After problems with the spring that supplies the tank, I wanted an easy way to check the tank level is full during the winter months without having to go and look. I installed the level sensor at just below the full tank level and can now check the tank is full via my phone app. As I use water, the level drops and the sensor reports this and again once the tank level is restored. The product can be configured to alarm when the level is high or low and can automatically email if that is your thing. I've turned off all alarms and just manually monitor and there is an alarm log which shows all the changes too. 4/5 stars as sensor is very lightweight and the mounting bracket is quite flimsy. Overall a great product though and will save me lots of hassle over the winter.

Not brilliant
Works fine for a few days then seems to disconnect from the WiFi, connect it again might not ok for a few days, might be a few minutes, might reconnect itself after twenty minutes or might not, but hit and miss. Text facility probably won’t work in the UK as most UK carriers have dropped this facility do email notification only. All in all when it works it’s good but not worth £79
