MQTT switch on rpi1 and light on rpi2

[goblin]

hello experts,
i have two Rpi's with Domoticz and want to use a switch button on the client to switch a light on the server and v.v. via MQTT
Sounds simple but can't get it work.
assume i have a situation like mentioned in "https://www.domoticz.com/wiki/MQTT#Architecture" where "other" is my second Rpi.
Can i use "on Action/Off Action" at edit light-switch ?

Thanks,

RPI 3

Why MQTT and not device sharing? https://www.domoticz.com/wiki/Setting_up_Device_sharing

Can i use "on Action/Off Action" at edit light-switch ?

If there is no specific need to use MQTT you could simply use

Code: Select all

http://<target domoticz ip: target domoticz port>/json.htm?type=command&param=switchlight&idx=<target device idx>&switchcmd=On
http://<target domoticz ip: target domoticz port>/json.htm?type=command&param=switchlight&idx=<target device idx>&switchcmd=Off  

in the On Action / Off Action fields of the edit switch screen of the source system.

You will have to allow password-less access for your home LAN (Settings: LOcal Networks (no username / password) or include passwords in the JSON API for this to work.
Using this method you are not limited by the requirements of the shared devices setup (same endian / same version)

I've done a Node-Red flow named Domoticz to Domoticz. You can adapt it to you. Is available on the node Red site.
With kind of switch device you use?
