Hi all, I am new to to the forum having just set up my shiny new HC2 (running 4.049). Apologies in advance if I get the termonology wrong - it is all new to me! On my test bed I have a Secure SRT332 comprising "electronic room thermostat" and matching receiver (an SSR303) associated together and configured using the HC2 heating panel to control my central heating gas boiler. This all seems to work (on my test bed). I now want to use a separate SSR303 receiver to control the hot water heating (on the gas boiler) by programming a Lua scene to turn the SSR303 ON at a particular time and OFF at a later time. My problem is that I cannot find the appropriate Lua commands to turn the SSR303 either on or off. In the Lua program I have tried fibaro:call(16, "turnOn" fibaro:call(16, "Heat" and variations of these command words. But without success to turn the hot water on. I am assuming the SSR303 is the same as a Horstman HRT4 ASR-ZW (it looks the same . The HRT4 manual states: "Thermostat mode Command Class; Only "Off Mode' and "Heat Mode" are supported with in this class, which can either set or read. Can anyone explain what I need to code to turn the SSR303 on or off?? I would hope this is possible The Lua script I wrote to test the hot water heating works fine when controlling a Fibaro FGS212 (2.5KW relay switch) but when I modify the ID to the SSR303 - nothing happens with the SSR303. And.... I want to use the SSR303 as it will match the SSR303 controlling the central heating boiler AND it has the built in failsafe mode (to turn the boiler off after 60 mins if no instruction received), and the manual on/off buttons to over ride current switch state. Can anyone help?? Many thanks Ian

Hello, I want to add "Declared power consumption" parameter to Horstmann ASR-ZW receiver unit (a.k.a Secure SSR303). And then view it in Energy Consumption Panel Anybody an idea? Thanks
