All,
for establishing a MQTT based solution for a power reducer box I am step by step getting there.
Sending an R/<ID>/keepalive even with filtering for example to ["settings/#"] works from scratch via MQTT broker, but I am not getting it up with NodeRed. As I want to shoot every 60 seconds, Node-Red would be the perfect solution.
It can only be a "JSON Format" issue, but whatever data format I chose (string, JSON, ..) it does not work.
Can anybody please educate me, what I am doing wrong? I have literally tried everything (with brackets {[]}, w/o, etc.
