So, after a month of my installer trying and failing to get a Rolec charger working, today they swapped it for an Elvi. Trouble is, that's not working either. Anyone out there with one? The problem is that when I try to add the charger to my account using the "Hey" app or website, the page that asks for the station ID complains that it's not a valid ID. I'm 100% sure that it's the correct ID since it is printed both on the rear of the device and also on a label that's stuck onto the "welcome" card that came with it. The ID is also being advertised as a Bluetooth device too. However, on a deeper level, I'm totally lost as to how it all works anyhow. The charger is supposed to connect via WiFi, but I can't see anything in the instructions or on-line regarding setting an SSID or a password. Do you need an open network? In which case, does it need a specific SSID? Help!
