Yes it works perfectly, you rock !

THANKS

Waterpressure is reported in PS:1 reports:

00:39:57.617781 00000000/00000000,10.00,00000000/00000000,100.00,0/0,15.00,0.00,1.30,19.76,51.20,48.30,10.90,41.70,0/0,0/0,0.00,70.00,8869,0,0,59136,14684,0,0,0

Could you add this water pressure value to Domoticz as a sensor?

OTGW firmware 4 supports thermostat-less operation. Domoticz would be able to send Control SetPoint (desired DH water temp) to the boiler based on some simple calculations on room temperature (from any temp sensor connected to domoticz) and the desired room temperature (maybe some thermostat-sensor ...

The OTGW does report the much wanted sensor values when in default reporting mode:

23:25:46.115610 BC0110000 Read-Ack Relative modulation level: 0.00
23:25:49.834102 BC01201B3 Read-Ack CH water pressure: 1.70

I was looking at a log-window which shows the serial data going back and forth between domoticz and the OTGW, that is how i concluded that domoticz doesn't sent TT command the first time i change the Room Setpoint in the webinterface... However i must admit that i was only actually seeing the data ...

When using PS:1 to get details from the OTGW like domoticz does, it seems the otgw doesn't report system water pressure, and doesn't report relative modulation level. When the OTGW is in it's default reporting mode (direct reporting of all OT messages) then these values are reported correctly. Maybe ...

I noticed another little something: Changing the Room SetPoint always has to be done twice in a row to make domoticz send TT:<new value> to the OTGW only in the second try. Also it takes about 2.5 minutes for the thermostat to actually change the setpoint value in its display to the new value.

When using Opentherm Gateway with firmware 4.0 beta 3 -> the DHW Setpoint is always 0 in Domoticz. This is the data from the gateway: 00000011/00000010,43.00,00000000/00000000,100.00,0/0,20.00,0.00,1.60,19.90,35.40,54.50,12.20,34.80,0/0,0/0,0.00,70.00,72990,0,0,58340,146460,0,0,0 The sixteenth value ...

Using the opentherm nefit converter on the smartline HRC24 with Honeywell chronotherm vision modulation thermostat the system is not working ok as the Control Setpoint switches between the normal temperature for heating the house and a fixed 10 degrees every 5 minutes. Example: 3/27/2014 13:45 60 3 ...

I have a Nefit Smartline with Opentherm converter module, and the Honeywell Chronotherm Vision Modulation (TH8110M1003) Thermostat. Both are connected to the Opentherm Gateway running the latest stable version 3 firmware on it. In domoticz it all is working just fine! There is one little detail i ...
