Control OTGW over Wifi by MQTT and Domoticz

[Bluebird]

Hi all,

I have connected the OTGW by Wifi and MQTT to Domoticz.
I see all the OTWG parrameters in Domoticz in the form of devices.

But what is the way to change these parrameters?
Ik MQTT explorer is see changing the domoticz/out items, but how to control the OTGW?

Thanks in advance
Henk

I have OTGW connected via USB and then I can use the following dzvents command for example to switch the setpoint to 16 degrees.

Code: Select all

domoticz.openURL('http://127.0.0.1:8080/json.htm?type=command&param=sendopenthermcommand&idx=8&cmnd=TC=16')

where 8 is the hardware idx of the OTGW (menu "setup", "hardware")

Don't know whether it is different in your setup.

Why over MQTT and not the build in OTGW gateway? See wiki https://www.domoticz.com/wiki/Opentherm_Gateway_OTGW

Thanks for the replies!

Problem solved!

But the documentation is not very clear en spread over several places.

Tell us more, how did you solve it and what documentation did you use? This for the next user that runs into this issue. If needed I can update the Domoticz wiki. I do not have a OTGW so for me I am relying on the info from you users.
