Node-Red Tasmota Error: connect ECONNREFUSED 192.168.77.21:1883

Question

I installed the Node-Red addon: "node-red-contrib-tasmota". When I try to use the "sensor" node, I get the error "Error: connect ECONNREFUSED 192.168.77.21:1883".The ESP32 is connected locally to "http://192.168.77.21/" and uses port "1883"

I tried changing the ESP32 configs in Tasmota, but it didn't work.

Answer 1

The sensor will be connecting to a separate MQTT broker, it will not be running it's own MQTT broker on the device. You need to user the IP address of the broker, not the device.
