i don't have anything connected. Just the plain V2 controller.
i've bought one expander in the first order but is still in the bag.
a controller reboot would be ok, a little bit over kill but better than nothing
maybe an i2c hard reset from Raspberry would be enough?
(starting from this night freeze, the pH controller is disappeared. obviously i've already rebooted the Pi)
i'm not sure that my fix won't work, because the i2c bus worked with no issue at all from the day 1, i've never had any single issue with the bus, then, immediatly after updating to v6.5 (3-4 days ago, i dose easy sps every 3 days), the first dosing (with the new retry) froze everything. A little bit strange for a coincidance. Also, the write succeeded (dosing pump started properly) and the read, done with the next line in the code after a 5ms delay, failed ? Maybe a too small delay or similiar ?
