Expected Behavior

System should be running

Current Behavior

Every few days it disconnects like this, I have to log into manager app and connect to the device then it seems to work. The ECU is never not able to be accessed through the EMA App.

PV-hardware (Environment)

System is in basement (one story house) but never loses connection via app.

2.3.0 installed

The error tells me that the ECU is receiving empty datastring from the inverter(s). What is the signal strenght on the inverter(s)? Try to bring the ECU closer to the inverters for a while and see if that helps. And I'd recommend installing 2.5.1

[kjroberts03]

It just cut out again, so before I reset it the inverters were showing anywhere from 12-21 dBm, with two of them showing -27 dBm at the time of cut off.

Let me see what I can do with the inverter and moving it closer. Will update.

I have converted this thread to the discussions section because it is not a bug, the error message was solved in a later version.
