After the app was upgraded neither of my two sensors would connect to the app on my phone. I spent ages trying to get them to work. In the end I removed in-line fuse from the battery sensors, waited a minute, and then replace them. When I restarted the Bluetooth connection on my phone both started to work as they should. Hopefully, this information may help others overcome the frustration I've had with CTEK?

DONT GET THIS PRODUCT. App looks ok, but some updates make it worse and others make it better. It's like they don't test before releasing an update. Also the sender connects the first time, then it looses connection after a few days and won't give you any more readings. You can clear the app and start fresh, but it's a time consuming process and you loose your ability to track any change.

Voltage works, that is all. Graph updates only occasionally. My battery went down to 6v, still showed a green battery on the display, no warnings so absolutely useless. Range variable, sometimes I have to walk right up to the car to get a reading, sometimes OK through the window at 10 metres. Sender unit not worth the money as it only works with the app.
