Sonoff dimmer control with MQTT Shims

I feel embarrassed to ask but cannot see how to do it

Up to now I have implemented several devices but none with a variable like a dimmer.

Attached is the setup for Study Lamp.

From the main panel selecting turn on of off switches the lamp but the dimmer slider does nothing.
If on the device I set the dimmer action payload to a number between 1 and 100 this correctly sets when the lamp is switched so how do I get the slider to input the value to the device.

I am sure once explained once it will be obvious.

Sending commands directly to the broker works fine

Thanks in advance for your help


BTW the dimmer is a sonoff D1 flashed with Tasmota 9.2

From the main panel selecting turn on of off switches the lamp but the dimmer slider does nothing.
If on the device I set the dimmer action payload to a number between 1 and 100 this correctly sets when the lamp is switched so how do I get the slider to input the value to the device.

What do you mean by "If on the device I...."? What UI are you using?

What's the exact command you send to the broker to set the brightness value?

Thanks for the prompt reply
From the indigo device panel i naively assumed i could select, in my case study lamp, and toggle the power and dimmer settings from the option at the bottom of the device panel.
Switching the power works but not the dimmer.
Maybe an issue with my dimmer device settings?

I proved i can talk to the dimmer via the terminal window
Williams-Mac-mini:~ Smedia$ mosquitto_pub -h 192.168.2.151 -t cmnd/Study_Lamp/cmnd/Power -m on
Williams-Mac-mini:~ Smedia$ mosquitto_pub -h 192.168.2.151 -t cmnd/Study_Lamp/cmnd/Dimmer -m 10
Williams-Mac-mini:~ Smedia$ mosquitto_pub -h 192.168.2.151 -t cmnd/Study_Lamp/cmnd/Dimmer -m 100

Which work fine

Help with the indigo setup would be appreciated

The topics you show in the commands above do not match what you show in the screenshot. Check your settings for the "On/Off Action Topic" and the "Dimmer Action Topic".

Thanks very much
Cracked

I have a last issue i cannot crack.
How do i get the state to be correctly reflected?
I have a trigger component with STATE and RESULT but i am obviously missing something

Thanks in advance

The state value for the lamp is not in the topic, it's in the payload. The topic is going to be 'tele/Study_Lamp/STATE', but I can't see the entire payload to see what it's called there.

So at a minimum you need to change the "State Value Location" to "Payload", then put in a key value (which I can't see). You also need to make sure that you have a trigger for the 'tele/Study_Lamp/STATE' topic that matches the '##SONOFF##" message type.

Have you gone through all the steps in the basic guide? https://github.com/FlyingDiver/Indigo-S ... asic-Setup

Thanks for the update.
Yes i have looked at the basic guide
I still cant get my head around how to use the payload as from the device you get an array of all the parameters.
See attached a couple more pictures so you can hopefully point me in the right direction

Thanks again for your help so far

I can't read those screen shots at all.

Please copy and paste the status update topic and payload into this thread. Text, not image.

And use the "Write Device Template to Log" menu command to get the Shim device definition and then copy that to a reply as well.

Ah i assumed images were attachments.

Status update topic
tele/Study_Lamp/STATE

Payload i guessed
{{POWER,Dimmer}}


message_type: '##SONOFF##'
props:
SupportsSensorValue: true
SupportsStatusRequest: true
action_template: cmnd/{{uniqueID}}/cmnd/Power
brightness_scale: '100'
dimmer_action_payload: '{{brightness}} '
dimmer_action_template: cmnd/{{uniqueID}}/cmnd/Dimmer
off_action_payload: 'off'
on_action_payload: 'on'
state_location: payload
state_location_payload_key: POWER,Dimmer
state_location_payload_type: raw
state_location_topic_field: '1'
status_action_payload: '{{POWER,Dimmer}}'
status_action_template: tele/{{uniqueID}}/STATE
uid_location: topic
uid_location_payload_key: RESULT
uid_location_topic_field: '1'
value_location_payload_key: STATE.brightness
trigger:
match_list: '["Match: devices", "Match: tele", "Match: SENSOR", "Match: stat"]'
queueMessage: true
type: shimDimmer

The images were attached, I just can't read them well enough to see the actual text.

You can't guess at the payload. I need to see the actual payload for that topic, either from the MQTT Connector log or from something like MQTT Explorer.

Also, the Trigger definition doesn't match the topic you specified.

Using MQTT Explorer, if you click on an actual payload line in the left column, it'll show the complete payload on the right, with an icon above to copy it to your clipboard, Which you can then paste into a forum message reply.

Hopefully this

Code: Select all

{"Time":"2021-01-18T19:36:59","Uptime":"0T01:45:10","UptimeSec":6310,"Heap":26,"SleepMode":"Dynamic","Sleep":10,"LoadAvg":75,"MqttCount":2,"POWER":"ON","Dimmer":92,"Fade":"OFF","Speed":1,"LedTable":"ON","Wifi":{"AP":1,"SSId":"Wildone","BSSId":"4E:1B:86:C0:F2:53","Channel":8,"RSSI":100,"Signal":-48,"LinkCount":1,"Downtime":"0T00:00:04"}}

Ok, so the relevant part of that JSON payload is:

Code: Select all

"POWER":"ON","Dimmer":92,


Which means you need the Shim config to look like:

You also need to make sure the trigger is correct, as mentioned above.

Thanks
I will experiment with the trigger
