you must use MQTT and use the message persistance features in order to do this (I have this feature in some of my modules even thou I don't use Domoticz)

To clarify, papperone says you must activate the "MQTT retain" feature on the advanced tab.
Domoticz on Raspi 2 -- 14 ESP units (hacked Sonoff,NodeMCUs, Wemos, self-built units) running with RC140- Mega 2.0.0 dev8

yes indeed, thanks for clarification, and as well in all devices that can send that message!
(in my case I can toggle a switch from the GUI which runs on a RaspberryPi and those message must be sent as well with the retain activated else the setup will not work properly!)
