I've recently got a nodoshop opentherm gateway running with nodemcu wifi.
I'm trying to update the firmware to 4.2.8.2 (from 4.2.7) using otmonitor (4.4.1) but it repeatedly fails, I get a variety of errors.
On hitting "Program" sometimes it sits there for a while saying "Switching to self-programming mode" after a while then saying "Could not switch gateway to self-programming mode".
Sometimes it will say "Firmware update failed - 0 errors".
I've seen it also say "Manually reset the device", which I've done via powering the gateway off, leaving for a few seconds then back on. Also trying shorting the RESET jumper on the gateway.
Nothing I try seems to work. I have read that on boot up the device should be in self-programming mode for 1 minuter but I've tried rebooting it then immediately attempting a firmware push but that doesn't seem to work either.
Does anyone know if I'm doing anything wrong, are there some clear repeatable steps I can follow to push firmware via wifi?
