Hi,
I have Openevse hooked up to Home assistant through MQTT and all worked well since installation a few months ago. In the last few days I noticed openevse seems to struggle turn on the charge and keep it on. Relay keeps clicking on and off within a few seconds interval… No recent upgrades, changes or anything it just stopped working reliably as it did for the last few months. I have captured what it does in the debug logs below:
{“state”:2,“vehicle”:1,“colour”:3,“manual_override”:0}
{“amp”:0,“voltage”:240,“pilot”:32,“wh”:2365734,“temp”:173,“temp1”:false,“temp2”:173,“temp3”:false,“temp4”:237.5,“state”:2,“vehicle”:1,“colour”:3,“manual_override”:0,“freeram”:213800,“divertmode”:1,“srssi”:-67}
{“state”:3,“vehicle”:1,“colour”:6,“manual_override”:0}
{“amp”:31240,“voltage”:240,“pilot”:32,“wh”:2365734,“temp”:173,“temp1”:false,“temp2”:173,“temp3”:false,“temp4”:237.5,“state”:3,“vehicle”:1,“colour”:6,“manual_override”:0,“freeram”:213752,“divertmode”:1,“srssi”:-64}
{“state”:2,“vehicle”:1,“colour”:3,“manual_override”:0}
As I understand state 2 is connected, state 3 is charging followed by amp message. But I cannot see anything above to suggest why it changes from state 3 to 2 again. there are no timestamps, but it stayed on state 3 for about 5 seconds before stopping charge and changing to state 2 again. I only pasted the output of one cycle, it keeps doing the above in a loop.
Before it started to behave like this full-time, it did eventually manage to keep the charge on after going through several cycles of on/off late last week. I just could not get it to work last night as my night tariff kicked in, ended up going to bed defeated on granny charger at 2am and short of miles in the morning as a result!
I first thought it was home assistant flows messing about, but having HA completely diconnected off the network I observe exactly the same behaviour when controlled EVSE manually from the web page. I only bought it a few months ago, looks like there is a fault with the variable relay potentially? Is there anything else I’m missing? Anyone seen similar behaviour?
