2 weeks ago the arbitration wrt poll is answered here: https://github.com/john30/ebusd-esp32/issues/14#issuecomment-2330578593 for the potential issue with the adapter not connecting to wifi during power off-on (if I understood it correctly), please open an issue in the right repo if desired (and also state the version currently in use): https://github.com/john30/ebusd-esp32/issues other than that I don't see an ebusd issue here, so closing

Description
Hi John,
I face several different arbitration errors.
1) I have a recovair 275. This is working just fine. However I built an automation that turns off the power for it when the outside air is to moist or too hot so as to not get that inside. When I do that and the device is off for some hours and then turns on again, the log file shows arbitration lost error messages...I don't have the log file handy anymore, once I see it again I'll submit it.
ebusd is running while the power is off, and tries to read which of course it can't. The only solve is to physically remove the power from the ebus shield v5 and plug it in again, then it recovers.
Do you know why this happens? can I recover in some other means that does not require me to physically reboot the shield?
2) sometimes when the loxberry boots and changes the time too late with ntp I also get arbitration errors. Again the only solve is to physically reboot by power cycling the shield. I have in the mean time worked to ensure ntp is fully synced before ebus starts, but I still wonder how to avoid the physical power cycle
3) I now get arbitration lost error on my geotherm vs 83 for some read operations
99% of requests are successful though, so I am not sure what is up
One piece of extra info, I run two shields (recovair + geotherm) and thus two ebusd on a loxberry (rasberry pi 4) connected both with usb and enhanced arbitration

Actual behavior
getting arbitration errors when air flow looses power and gets it again and in other situations
Expected behavior
I want to avoid the error message in the first place, but if that is not possible, would like a software solve instead of physically having to go to my basement and reboot the shields ;)
