Why switchOn sends brightness:254 instead of state:on?

[dariann]

Hi All,

I have a power supply driven by zigbee2mqtt which is activated by sending data to the "zigbee2mqtt/pwr_bookshelf1/set" topic. I am toggling its state by "switchOn" and "switchOff" like in this script:

Code: Select all

return {
	on = {
		devices = {
			'btn_square1_action_on',
			'btn_square1_action_off'
		}
	},
	logging = {
		level = domoticz .LOG_INFO,
		marker = 'btsqonoff',
	},
	execute = function(dz, dev)
		dz. log('Device ' .. dev .name .. ' was changed with value: ' .. dev .state, dz .LOG_INFO)
		if (dev .state == 'On') then
		    dz. devices('pwr_bookshelf1').switchOn()
		else
		    dz. devices('pwr_bookshelf1').switchOff()
	    end
	end
}

On "switchOff()" call I see {"state": "OFF"} in the topic payload, but on "switchOn" call see {"brightness": 254}. Does anyone know why? I expected {"state": "ON"}, but I don't know how to change it. With "brightness" set directly, my led light is turning on instantly, while with "state" it does smoothly.

I suppose that it may be somehow connected with device type, but I am not sure. Anyway, at Domoticz devices list, the "pwr_bookshelf1" device type is "Light/Switch" and subtype is "Switch".

Thanks!

After some digging, I have noticed that on "Switches" dashboard I have a switch "pwr_bookshelf1" with description "Light/Switch, Switch, Dimmer", so I clicked "edit" and changed "Switch Type" from "Dimmer" to "On/Off". As a result, I started getting payload {"state": "ON"} as expected, but dimmer functionality was gone.
Does anyone know how to preserve expected payload with dimmer functionality?

Why do you want to know this? Do you want to interfere with the Domoticz/Zigbee2MQtt interface?
You can go the the MQTT AUtodiscover hardware source code to find the logic: https://github.com/domoticz/domoticz/bl ... scover.cpp

Also check the MQTT AD documentation for switch/light: https://www.home-assistant.io/integrati ... son-schema

[dariann]

Because of the behavior "pwr_bookshelf1" which is different depending on the payload. In case it is:

• {"state": "ON"}, the LED light is turning on smoothly

• {"brightness": 254"}, the LED light is turning on instantly

I would like to turn it on smoothly instead of instantly, thus my question. Is it feasible? Or, maybe there is an other way?

What is the discovery mqtt message content for this device as that is used to determine what to send for On?

[dariann]

Could you tell me which topic of zegbee2mqtt says that?

For instance, using MQTT Explorer I found this one:

* homeassistant/select/0x84fd27fffe47d363/power_on_behavior/config

and this one:

I haven't found solution, so I used Node-RED for this and it works very well, so maybe this message thread should be placed in different topic? Maybe which is about Zigbee integration with Domoticz, but I am not sue.

Anyway, below is a screenshot of Node-RED nodes which I used. Unfortunately, my Ikea button states:
https://www.zigbee2mqtt.io/devices/E1743.html
are recognized in different topics by zigbee2mqtt, but not JSON payload. However, using change nodes I replaced payload with required by power driver:
https://www.zigbee2mqtt.io/devices/ICPS ... -IL-1.html
and it works as I wanted.
