Open / Close workplace with MQTT message
At hackerspace TkkrLab we use MQTT for all our domotica appliences such as status if we are open or closed. We already had this automated for our main/social room. We would also like to have the same function in our workplace.
I used a M5StickC as button and display. On the display you can see if the workspace and main room is open / closed.
If you want to use this code, copy the 'config_sample.h' to 'config.h' and change the value acording to your situation.
