@anand There was vastly more time wasted trying to get the original concept to work, than it look to learn basics of Domoticz scripting after finding a solution used by others.
The sketch complexity and size is dramarically reduced for the Node, it still responds to changes in boiler or PSU condition within a second, and reports temperatures and power condition regularly.
Domoticz reconciles everything to default 5 minute time slots, this method provides boiler run times to an accuracy of a minute which is quite adequate.
I have found a workaround by sending the heartbeat message as a separate V_MULTIMETER child. This then gives me a voltage reading of 0V every 30 seconds that I can use with the Domoticz last update feature
Would like to hear any better ways of doing this.
MySensors is built around nodes that collect data and send it over radio to a gateway connected to the controller.
For your application, it sounds like you would create a node that collects information from your controller. Then you would need to add a MySensors gateway to your Domoticz setup.
I'm not sure what you mean when you say your controller can transmit the information. If your controller and Domoticz are on the same network, you could have your controller send data directly to Domoticz using http. There is info about that in the Domoticz Wiki. Or, if your controller and Domotics are on the same network, you could add a MySensors MQTT gateway to the network and have your controller sent data using MQTT messages.
Take a look at the Getting Started and Build pages on this site and you will get a good idea of how MySensors could fit in.
Couldnt get it to work, so the gas and powermeters where replaced after a call to the Energy company. The new P1 smartmeters is connected with usb to Domoticz and works like a charm!
