I'm missing more events like burnerhours/starts etc. It would be nice if OTGW monitor would post every message (with a changed value) to mqtt.
I tried to dig into the source code and i'm having trouble to figure it out. I think it has to do with the $signals object not containing all data items. But not familiair with the language and build environment.

# Publish all known persistent parameters
dict for {key args} $signals {
if {[llength $args] == 0} continue
set param [string tolower $key]
if {[info exists gui($param)]} {
mqttsignal $param $gui($param)
}
}

Yes, i just mentioned 2, but all events would be welcome ofcourse :-)

I'm waiting for a year now.....but I still hope it will be implemented eventually...

I admire your patience to wait a year for someone else to do something for you. Of course you could also have spent a rainy afternoon to figure out how to do it yourself.

I wish I could, Ihen I had done it a long time ago. :D
But good to see you pushed it to github https://github.com/hvxl/otmonitor

It was just positive feedback to make OTGW better then it already is.

thx

Where in otmonitor.tcl can I do this calculation?

DeltaT = BoilerWaterTemperature - ReturnWaterTemperature

And put it in set signals, I assume...

This is nice, this will save me the effort to extract this data from the otgw by hand!
I've been able to compile the updated sources from Github into a binary that runs on my orange-pi otgw, and I've got several new topics available in my MQTT broker: https://imgur.com/a/Ej3oc8U

Thanks for the effort to create that PR @timoline!
