For some reason my Opentherm gives periodic misreadings and sends them to my domoticz system.
within my dzvents scripts to control radiators i ingnore values below 10 when reading my thermostat temperature of the livingroom.
Is this a known issue?
is it possible to fix this within domoticz?

No, this is an Opentherm issue. Did you ask Opentherm Gateway if you can prevent these misreadings?

Could also be an issue in the thermostat, instead of Opentherm gateway.
Striking that it is a very regular pattern, every hour, but then some periods during the day no issue.
Every day the same pattern?
