Value not writeable via MQTT

[ulrichsc]

Description

I have a message defined as:

b,energymgr,z1_heat_mode,Z1 Heating Mode,,fe,2020,c679,,,UCH
w,energymgr,z1_heat_mode,Z1 Heating Mode,,fe,2020,c679,,,UCH

When the message is broadcasted on the bus, it is parsed and published via MQTT (I can see it passing with mosquitto_sub as ebusd/energymgr/z1_heat_mode).
Setting the value via ebusd works,e.g. ebusctl write -c energymgr z1_heat_mode 2

Setting the value via MQTT (e.g. mosquitto_sub) is ignored.
mosquitto_pub -h 172.20.20.155 -p 1883 -u "ebusd" -P "<secret>" -t "ebusd/energymgr/z1_heat_mode" -m 3

Is setting values via MQTT not supported or am I missing something?

Actual behavior

Setting the value via MQTT (e.g. mosquitto_sub) is ignored.

Expected behavior

When setting the value via MQTT it is passed to the bus.

Jumping in here because I made the same mistake: for writing to a topic you should use the /set sub-topic

In your case you should publish to the topic ebusd/energymgr/z1_heat_mode/set
