Title: MQTT Subscribe For Idiots
Post by: Ssweber on December 29, 2020, 03:54:23 PM

For future people, who like me do not understand MQTT at all.

MQTTSUB seems totally non-blocking. You literally subscribe to a topic and when the topic changes remotely, it updates the payload. BRX handles the rest.

I had it setup where I turned off the rung on an "On Success" (like you would with an email), and couldn't understand why it wasn't updating my payload. Duh  :o
