Ignition Maker Edition Version: 8.1.2 (b2021020311)
MQTT Engine Module 4.0.6 (b2020111920)
I am having an issue reporting certain topics via MQTT Engine into Ignition. I am running a mosquitto broker and have 4 relays connected to it and reporting status, as well as commanding the relay ON/OFF (I am using SONOFF relays with Tasmota firmware - https://tasmota.github.io/docs/MQTT/)
I have configured the MQTT Engine module to connect to my broker, and I have a custom namespace that points to the “home/lab/#” topic – configured to parse as JSON. Here is the module configuration:
I can see most of the topics in the tag browser:
However, when I turn the relay ON or OFF (by publishing a value of “0”, “OFF”, “1”, or “ON” to the topic /home/lab/relays/relay1/cmnd/POWER”, the following error message appears in the log:
The relay triggers just fine, but the error message appears in the log, and the …/cmnd/POWER topic does not show on the tag browser.
Here’s a screenshot of a client directly against the broker:
