Domoticz

Does anyone know of a cheap hardware push button that can communicate with Domoticz. My setup has a RFXtrx433 antenna for 433mhz devices and also a Philips hue is connected. I am looking for a small hardware push button to trigger a domoticz (virtual) button so it can start a script.

Try this:

It uses the PT2262 protocol - I've set this up in NodeRed, using the rfx-PT2262-in node, to publish a message to domoticz/in.
