JDB found but times out

wimg commented 9 months ago

Attempting to use batmon-ha with a JDB BMS. It seems to be found, but then it times out trying to get data from it.

Tried a number of the steps described in troubleshooting, but none seem to make a difference.

Paste log output between BEGIN and END:

The above exception was the direct cause of the following exception:
