Its probably a bit messy but what about; commandArray = {} if (devicechanged['WiFi'] == 'On') then print('Switched LightwaveRF On') os.execute("nc -u -w1 192.168.1.100 9760 < /usr/local/path/to/file/on") for i, v in pairs(otherdevices) do print(i, v) end elseif (devicechanged['WiFi'] == 'Off') then ...

Thanks for the code and the reply, that explains it all very nicely. The RFXCOM has arrived, and as expected works with LightwaveRF and Domoticz straight out of the box. However, since I've started looking at the wifi link I'd like to see if that can be made to work as well - just for the sake of it ...

Whilst waiting for a RFXCOM transceiver to arrive I've been wondering if I can get Domoticz to work with a Lightwave RF Wifi Link. The Wifi Link receives a UDP datagram which it converts to a suitable 433MHz signal and turns On/Off the LightwaveRF device. So on my Pi I've added lua-socket via apt ...
