I want to experiment how MQTT works. But it is a big black box for me. I know that mqtt is a protocol. You need a broker(server) to use this protocol. I thought that a device is a MQTT client. But when I search the store I find different apps. Which do i need and what can I do with it.
So i can install f.i mosquitto broker on my NAS
Install, mosquitto MQTT client on Homey. How can my NAS communicate back to Homey. Must you install a Mosquitto client on your NAS, and which one?
I have quite some experience in working with MQTT and have a broker running on my NAS. In this way I can exchange information of a bunch of devices with Nodered flows that also run on my NAS.
I just managed to install the MQTT client (by Menno van Grinsven) on my Homey Pro (2023). I try to use it in a flow, but I don’t see any flowcards that return the contents (payload) of a received message! Without access to the payload MQTT becomes less useful.
Anyone knows how to get hold on the message payload?
Success! Once I convert the message text (using a logic flowcard) to a numeric value (#Result) an entry Logic Tvalue appears in the Insights menu. Great!
