What do these errors mean and how to fix?

what I don’t understand is why you are using a different logic for your command and status topics:

command: diana/cord1/cmnd/POWER (order: name/item/type/POWER)
status: stat/diana/cord1/POWER (order: type/name/item/POWER)

maybe this is how Sonoff works… not sure cause I don’t have one

I would use the same order (if possible) to avoid confusion in my topics (both inbound and outbound)


example: diana/cord1/cmnd/POWER for commands and diana/cord1/stat/POWER for status
I need to read the Sonoff stuff to be sure :slight_smile:

so, clearly, your command topic is: diana/cord1/cmnd/POWER

so in your item config, you should use:

... mqtt=">[mosquitto:diana/cord1/cmnd/POWER:command:*:default] ...

for the outbound part

Tasmota Wiki

Sonoff responds to the following MQTT commands using MQTT Topic for cmnd/sonoff/<command> and MQTT Message/Payload for <parameter>:

The relay can be controlled with cmnd/sonoff/power on, cmnd/sonoff/power off or cmnd/sonoff/power toggle. Sonoff will send a MQTT status message like stat/sonoff/POWER ON.

where as his “sonoff” is his topic.
So my topic is cord1

forget the wiki defaults :slight_smile:
I believe that you can customize the topics in your Sonoff device
did you change the defaults by any chance on the Sonoff? (I would)


Sonoff Basic Module


 MQTT parameters 

Host (domus1)

Port (1883)


Client Id (DVES_970D9F)






Topic = %topic% (sonoff)


Full Topic (%prefix%/%topic%/)



looking at the example from the master thread:

try to use:

Switch		cord1		"Cord-1"		<poweroutlet>		(Cords, Lights, Power)

topic structure:

for outbound commands: cmnd/%prefix%/%topic%/power
for status reports: stat/%prefix%/%topic%/power

just switched it to that

making progress I think. rebooting.

not sure if the last part of the topic should be power (with small letters) or POWER with capital letters…
try both :stuck_out_tongue:

looks nice & clean :sunny:

Well… somethings different. when I toggle through Habpanel,

2017-08-29 00:28:41.131 [ItemCommandEvent          ] - Item 'cord1' received command ON
2017-08-29 00:28:41.238 [ItemStateChangedEvent     ] - cord1 changed from NULL to ON
2017-08-29 00:28:41.238 [GroupItemStateChangedEvent] - Power changed from NULL to ON through cord1
2017-08-29 00:28:43.502 [ItemCommandEvent          ] - Item 'cord1' received command ON
2017-08-29 00:28:46.469 [ItemCommandEvent          ] - Item 'cord1' received command ON

but the icon reverts back to the off state.
going to try a lowercase :power"

post your current item config

maybe the command part is not working (the mqtt message is not being delivered) and your status part is working, so OH2 reads that the Sonoff is off and it changes the switch state to OFF

what is the real state of the Sonoff module? (on or off)

just changed it a bit. testing.

scroll down a bit.

open up a subscription to all topics using a shell command to check if the mqtt messages reach the broker at the correct topics when you toggle the switch from your OH2 sitemap:

mosquitto_sub -u openhabian -P Dxxxxxx -t '#'

(or use a tool like MQTT.fx etc to monitor the payload traffic to the broker)

looks ok
in theory, you don’t need to separate the on/off commands
cmnd/diana/cord1/power:command:*:default should cover both on and off

mosquitto_sub -u openhabian -P Dxxxxxx -t diana/cord1/cmnd/power

[00:36:33] openhabian@DianaHAB:~$ mosquitto_sub -u openhabian -P Dxxxx -t diana/cord1/cmnd/POWER
[00:38:20] openhabian@DianaHAB:~$ mosquitto_sub -u openhabian -P Dxxxxx -t diana/cord1/cmnd/power
[00:39:14] openhabian@DianaHAB:~$ mosquitto_sub -u openhabian -P Dxxxxxx -t diana/cord1/cmnd/power/"#"
[00:39:57] openhabian@DianaHAB:~$ mosquitto_sub -u openhabian -P Dxxxxxxx -t cmnd/diana/cord1/cmnd/power/"#"

not receiving from Habpanel

I really wish that I had a Sonoff to be able to help more :slight_smile:
I am not 100% clear on the correct structure of the topics… you need to play around with config options to find the correct method

by the way: if you want to use a trigger and a transformation, it should be the other way around (I think):

the trigger should be ON and the transformation should be 1

{ mqtt=">[mosquitto:cmnd/diana/cord1/power:command:ON:1], >[mosquitto:cmnd/diana/cord1/power:command:OFF:0],

(ON and OFF triggers with capital letters)

keep the subscription command open at the top level topic (#) (means all) at the shell and then toggle the switch from your UI and check what shows up in the shell while leaving the subscription connected continuously
