OTGW randomly stops #89

Closed PuckeyP closed 2 years ago

PuckeyP commented 2 years ago

Hi, I'm having a problem with the OTGW - NodeMCU in combination with Remeha Calenta and Remeha iSense. I'm using NodeRed /Home assistant to control the remote override setpoint.

All has worked well for about three months, but suddenly the OTGW randomly stops. Connection to the OTMonitor is lost, logging stops, and ch temperature is set to 14 degrees. Any ideas where to look for an error Thx, PPee

Can you confirm which version of OTGW you have?

Thank you

Hi tjfsteel, Details from the webui - Device Info:

tjfsteele commented 2 years ago

Can you tell me the hardware version? Should be written on the OTGW board e.g. 2.0

PuckeyP commented 2 years ago

Yes it is V2.0

@PuckeyP could you share some logging from your OTGW firmware, just telnet to port 23 and capture some logs and share them here. Maybe we can see if anything weird is going on.

PuckeyP commented 2 years ago

I attached the complete TelNet log. At 12:00 logging stopped unexpectedly. At 11:43:42 ch_enabled suddenly turned to "OFF" Hope you can find an indication of the error.

Hi @PuckeyP Well at 11:43 someone uses hotwater, so your boiler switches from Central Heating to Domestic HotWater... 11:43:42 [OTGW/value/JPEP_OTGW/ch_enable] --> Message [OFF] 11:43:42 [OTGW/value/JPEP_OTGW/dhw_enable] --> Message [ON]

I would think that's normal when you turn on your hotwater, the boiler then will switch to hotwater production and lets the thermostat know that it's doing that.

Your room-temperature at that point is: \ Tr = 18.24 °C

And the TrOverride = 18.00 °C, so actually there seems no reason for the boiler to turn back on once the DHW stops. However the hotwater production keeps going until the end of your log, so either you draw a bath, or, a long shower is taken at that point.

So far I don't see very strange things, I am about to release 0.9.1 which is going to clean up the logging a lot, and implements the override "gateway" function a lot better.

If you want to help testing that, you can come to the discord server to join us online: https://discord.gg/zjW3ju7vGQ

Hi Robert that is strange, because I did not use hot water this morning. Nobody was home until 13:00...

rvdbreemen commented 2 years ago

Hi @PuckeyP well, then that's very weird indeed, but that's what your boiler is reporting back to the OTGW according to your logs. Does your boiler have an error log history?

rvdbreemen commented 2 years ago

@PuckeyP just release version 0.9.1 that fixes the OT decoding. So please try that. I will close this issue in the mean time, if you still have problems, then please reopen this issue.
