Last week I went to update to the newest firmware and the CCGX wouldn’t recognise the Carlo Gavazzi grid meter anymore!
So I had to revert back to the patched version, and then it worked again. Why?
This issue where a very large jump in firmware version somehow loses devices is one we’ve seen a few times.
There is an issue in the settings migration, this is very rare, yet sometimes it happens, and it causes energy meters, and sometimes also PV inverters, to be unable to allocate a DeviceInstance, and then they don’t come up at all.
The solution is to do a factory reset of the GX, and then reconfigure it.
