very usefull but MQTT or JSON return

[kunux]

hello i'm not a programmer but your code looks very clean but to difficult for my understanding ans update it.
it 's working like a charm but i want to publishy the state state of the garage door to my domoticz application. so i van use my remotes and also have have status of the doors.
is it possible tu update a json status lire a new url.
-- when it 's closed send MQQTT or JSON url on another pi server running domoticz
-- when it's open sen MQTT or JSON as well

for exemple my domoticz accept this to update status of MQTT switch
mosquitto_pub -h 192.168.1.240 -t "domoticz/in" -m '{"idx" : 13, "nvalue" : 0}'
or "nvalue" : 1
sorry for my poor english.
