Domoticz

Guys,
I recently installed an OTGW in my domoticz system. I specifically bought a Remeha iSense thermostat since the original designer of the OTGW used one as well.

I can temporary override the setpoint from the domoticz interface, nice! This is done with the TT command (e.g. TT=19)

I want to be able to send a constant setpoint override to the thermostat as well (e.g. TC=19). I read somewhere that this is not implemented in the domoticz gui. So I am trying to do this from a script (e.g. bash or python). But I can not get it to send such a command. Can somebody tell me how to do this?

Thanks in advance!

What is the reason you have the OTGW in Domoticz?

You could also run the otmonitor-daemon on your system, this daemon also has a onboard webserver with a page that accepts serial commands.
Then setting the TC would be something like http://ip/command?TC=19

You could put that URL in the OnCommand of a virtual switch, or create a virtual thermostat and combine it with a Lua-script that sends the value of the virtual thermostat to that URL.

Hi ThinkPad,
I used domoticz because I only had to add the OTGW to get all the functionality without writing scripts, etc. If your solution works I can use that as well, no biggie.

I tried the otgwmonitor. It works without a problem on my Win7 notebook. However on my headless RPi I can not get it to connect with the gateway. I can start it up, connect to the webinterface, but do not know how to let it connect to my gateway (/dev/ttyUSB1).

This is my config file:
web {
enable true
port 8081
nopass true
}
connection {
device /dev/ttyUSB1
type serial
enable true
}
server {
enable true
port 7686
relay true
}

I start the otgwmonitor as:
./otmonitor-ahf -f otmonitor.config --daemon

Message log stays empty (if domoticz is running or not)

Can you tell me what I am doing wrong?

I noticed that since one of the recent Domoticz (beta) updates, you can send commands to the OTGW from the hardware configuration panel (Setup > Hardware > OpenTherm Gateway > Setup). Does anybody know if this can also be used in a (LUA) script or via the JSON interface?

Anyone? I have already tried a dummy device with a command, but can't get it to work.
It would be great if I could define a button with a OTGW command behind it!

1) create a dummy device in the hardware tab
2) create a virtual device of the type 'Switch'
3) find the switch (normally it is already at your switches tab) and click Edit
4) under 'On Action' you can now program e.g. a setpoint to be used by the OTGW: e.g. http://raspberrypi:8081/command?TC=19 and under the off action a command to revert back to the thermostat setpoint like http://raspberrypi:8081/command?TC=0 (replace the raspberrypi part with your ip address where the OTGW daemon is running, assuming you already have that sorted off course)

works like a charm, in the messages tab I do see the command being issued.

perhaps use the new setpoint in Blockley...
Works great.

Big Thanks.
Looked at several sites and probebly overlooked it completely.

Where did you spotted them?

Those url controlled commands are handy to create a selector switch with holiday/work-at-home/comfort etcetera.
