Good morning everyone.
I've woken up today to find that the unit IDs of my BMV-712 and solar charge controller have switched over night. According to the modbus guide FAQ, this shouldn't happen. I've seen the ID change on my solar charge controller previously, but wasn't actually using it for anything other than testing (I've still got the old device instance showing in VRM, so I can access the historical data).
This ID change has forced me to rewrite a large part of my customised remote interface, as I didn't think I would need to programatically find the device IDs. Does anybody know what the criteria is for these ID's changing, and if it is normal behaviour?
Thanks,
Simon
