Is anyone else having issues with their Growatt inverter not accepting any commands? My last successful one was at 3:30 this morning, and I've not been able to issue anything from the web interface or the Shinephone app either:

On the web I get "Set Parameter Failure" and on the app I get "Modification failed." It would be comforting to know it's not just me, but also useful to know if it is just me so I can carry on investigating the issues.
