I am trying to add an SMA eCharger 22 (EVC22-3AC-20) to SMA Devices Plus. The device is discovered correctly as an EnnexOS device via HTTPS. I can also access the local web interface of the eCharger with the same local administrator account.

SMA Sunny Island SI6.0	Not working Local	Entities flip unavailable every 20-30s over Speedwire on old firmware Saved copy I use 4 SMA devices (STP25, STP10, SI6 and HM2). All were recognized as Speedwire devices via the discovery and were also configured as such. The SI6 is a device from 2018 with an older firmware that I do not want to update (complete reconfiguration). The entities of the SI6 switch back and forth between “not available” and normal status approx. every 20-30 seconds.
