After over a year of trouble-free operation, my SmartView2 IHD suddenly lost its pairing with the meter and now seems to be stuck in a perennial loop, trying to reconnect to the meter:
Restarting it next to the meter, taking the battery out etc. didn't work. I got on WhatsApp to E.ON Next, and they apparently sent a command to the meter to reset the pairing overnight. In the morning, after restarting the IHD, it briefly displayed a "Woohoo you're connected!" splash screen, but then it went back into the infinite pairing loop.
It beggars belief that a device that allows little to none user interaction still manages to brick itself for no apparent reason. I wonder if it's possible to remotely install software or firmware updates onto the SmartView2, and maybe one such update went horribly wrong? Or maybe its design was just cr*p from the start, and the device is doomed to fail sooner or later: nice job.
Any suggestion welcome, before I resort to buying some other replacement.
