Python Plugin: MqttMapper

[hjzwiers]

It is working now.

"MQTTsignal": {
"topic": "homeassistant/easee/power",
"type": "243", "EnergyMeterMode": "1", "subtype": "29", "switchtype": "0",
"mapping": {"item": "~*;~0","multiplier": 1000}

Thanks a lot!

[FlyingDomotic]

Happy to heard that!

However, syntax is not the right one (so "EnergyMeterMode": "1" is ignored and may be missing in device). This don't make plugin to crash, but is just ignored.

Right syntax is:

Code: Select all

"MQTTsignal": {
	"topic": "homeassistant/easee/power",
	"type": "243", "subtype": "29", "switchtype": "0",
	"options": {"EnergyMeterMode": "1" },
	"mapping": {"item": "~*;~0","multiplier": 1000}
}

Strange that is had a positive effect.

I updated the file and its still fine, again, thanks for the help!

[hjzwiers]

Sorry to bother you again, but I have a MQTT value that is not updating:

value in MQTT Explorer:
RunDataCompressorSpeed = {"value": {"value": 30}}

and a Mqtt file:
"RunDataCompressorSpeed": {
"topic": "ebusd/hmu/RunDataCompressorSpeed",
"type": "243", "subtype": "6", "switchtype": "0",
"mapping": {"item": "value/value"}
}

It just updated now, but it seems the frequency is not in line with the MQTT Explorer output. I did change the name, is that of influence?

[FlyingDomotic]

For type 243, sub-type 6 is percent, so value should be in range 0-100. Sub-type 7 (fan) should be better.

Hier I am again ... i just cant get it right.
I've used Zigbee2mqtt and I need the value of a lux sensor (and more late on). I've tried, but no succes. Hier my mqtt file and the file i used in mapper.

I need the values of the sensor and the water in Ulta-Dongle. Ive tried this but no succes:

}

}

I'm horrible with this .....

[waltervl]

@hjzwiers you are not using the standard MQTT auto Discovery for zigbee2mqtt? As for that value should be a lux sensor be created.

[hjzwiers]

I have auto discovery installed, but its not downloading?

I see the results in the separate website, is it a setting somewhere?

I changed the setting to force homeassistant, then auto discovery sees them. The last one is done (still leaves the other...)

Thanks!

Better discuss this in a new topic in the MQTT AD subforum, not here

MQTT AD subforum: viewforum.php?f=82

[hjzwiers]

I have solved the water sensor and light sensor!

I have one question remaining. I use the sensors in ebusd as sensors to contol that I still have a connection. These are booleans, which I cant read very well in domotics. I've tried nearly everthing but I can't work it out.

Try this:

Code: Select all

{
	"T_Outside": {
		"topic": "ebusd/Broadcast/Outsidetemp",
		"type": "80", "subtype": "5", "switchtype": "0",
		"mapping": {"item": ""}

	},

	"MQTTrunning": {
		"topic": "ebusd/global/running",
		"type": "244", "subtype": "73", "switchtype": "0",
		"mapping": {"item": "", "default": "0", "values": {"False": "0", "True" : "100"}}
	},

	"MQTTsignal": {
		"topic": "ebusd/global/signal",
		"type": "244", "subtype": "73", "switchtype": "0",
		"mapping": {"item": "", "default": "0", "values": {"False": "0", "True": "100"}}
	},

	"MQTT_Compressor": {
		"topic": "ebusd/hmu/RunDataCompressorSpeed",
		"type": "243", "subtype": "6", "switchtype": "0",
		"mapping": {"item": ""}
	}

}

[hjzwiers]

Now what do I use in domoticz to read out that signal?

Further with the temperature readout i have a mqtt server that "switches" between:

Outsidetemp = {"value":{"value":30.125}}
and
Outsidetemp = 30.125

which needs "mapping" : {"item": {"value"/"value"}}
or "mapping" : {"item": ""}

I keep changing it .....

[FlyingDomotic]

As of now, there's no direct way to do it.

But, as general workaround, you may store data into a string, analyze it, and store value with a script into a virtual device.

Code: Select all

"T_OutsideText": {
	"topic": "ebusd/Broadcast/Outsidetemp",
	"type": "243", "subtype": "19", "switchtype": "0",
	"mapping": {"item": "value"}
}

Content of "T_OutsideText" could either be something like:

Code: Select all

xxx.xx

or

Code: Select all

"value": xxx.xx`

You may write a small script that analyze "T_OutsideText" device content, and load another virtual temperature device depending on content (with or without "value":

Both values are true, so I would expect them to be 100?
also have the two temperatures that need to be scripted to the readout temperatures ... I don't really have a clue how to start, I have programming skills, but they are very limited. I thought that MqttMapper made the output blocks in domoticz, but for instance I deleted the charger output thinking it would be created, but it wasn't

[FlyingDomotic]

This is a strange thing about Domoticz.

It has nValue to set state, the first part of settings, and a sValue to set other things (including Level, which is from '0' to '100').

Here, on/off switches use only nValue (0=Off, 1=fully On, 2=between 1 and 99, included), but 1 in nValue means '100' in sValue.

I'm trying to make things simpler in next version (or the following) of MqttMapper, replacing 0 by "Off" and 1 (or 100) by "On", to make it clearer for users.

Outside this, does switches work as expected?

[hjzwiers]

I have some stuf to thing about. I get all the values from the ebusd, so an alternatieve is present.
I think the sensors work, don't know why, but I switched off the sensor and they went down, pretty amazing.
I think I will clean everything up, now every thing in docker files with dockge. I changed a lot lol

[FlyingDomotic]

Just a tip:

If you're making a change in Domoticz device definition (changing type/subtype or options), it could be a good idea to delete corresponding device, and restart MqttMapper (or Domoticz) as changing these characteristics on an existing device may sometimes fail...

[hjzwiers]

I was just wondering how to get the values. The script must run within MqttMapper.

This is the current logging:
2025-06-21 17:22:10.925 MQTT mapper: Pushing 'onMessageCallback' on to queue
2025-06-21 17:22:10.925 MQTT mapper: Processing 'onMessageCallback' message
2025-06-21 17:22:10.925 MQTT mapper: Calling message handler 'onMessage' on 'module' type object.
2025-06-21 17:22:10.925 MQTT mapper: onMQTTPublish found ebusd/Broadcast/Outsidetemp, Device 'MQTT mapper - T_Outside', message '{'value': {'value': 30.375}}'
2025-06-21 17:22:10.926 MQTT mapper: Setting MQTT mapper - T_Outside to >{
2025-06-21 17:22:10.926 "value": {"value": 30.375}}<
2025-06-21 17:22:10.926 (MQTT mapper - T_Outside) Updating device from 0:'{
2025-06-21 17:22:10.926 "value": {"value": 30.375}}' to have values 0:'{
2025-06-21 17:22:10.926 "value": {"value": 30.375}}'.

so the value is 30.375, but it is set to 0, also within devices it is set to 0. So where do I make the script?

[FlyingDomotic]

Are you sure device has been set to text ("type": "243", "subtype": "19", "switchtype": "0"), and device recreated ?
Could you check that "T_OutsideText" device is properly displayed into "Utility" tab?

[hjzwiers]

I know have {"value": {"value": 30.375}} as an item in my list: thanks a lot.

Now the conversion never done that before
