My bad. Apparently after issuing the subscribe command, I first get a bunch of retained events, that I have mistakenly taken for actual values. When I was just converting the timestamps in the MQTT messages to lookup the logs, I noticed the off-set in time.
After issuing PM=18 in otmonitor, the water pressure was updated, both in status window and MQTT . Sorry for bothering you. However the feature request still stands :-)

Hi dear OTGW users,

I also want to write a wa regulation within Node red.
I use an OTGW from the Nodoshop that functions satisfactorily. The OTGW runs with the default settings. What strikes me is that if the command sends CS=40 away, that indeed changes the setpoint, but then you regularly see the setpoint return a fraction of the old value at the same time as the burner is switched on and off. Does anyone have an idea what is causing this?

I don't understand what you are asking. Can you provide a log that shows the issue?
