Confirm. Works! Thanks.
So ~0 is third item of svalue in DZ?
As expected by this device in DZ?

Yep, device needs sValue=temperature;humidity;status
Status could be one of: 0=Normal, 1=Comfortable, 2=Dry, 3=Wet

I'am trying to get a switch in a remote domoticz install to function via MQTT in an other domoticz install.
So listening to the remote MQTT-messages I get these 2 json's when I switch off and on in the remote ....

============================================
{
"Battery": 255,
"LastUpdate": "2023-08-11 13:59:59",
"RSSI": 12,
"description": "",
"dtype": "Light/Switch",
"hwid": "24",
"id": "shellyplug-s-EF6165-0",
"idx": 1152,
"name": "5.2 TestShellyPlug",
"nvalue": 0,
"stype": "Switch",
"svalue1": "Off",
"switchType": "On/Off",
"unit": 5
}
============================================
{
"Battery": 255,
"LastUpdate": "2023-08-11 14:01:17",
"RSSI": 12,
"description": "",
"dtype": "Light/Switch",
"hwid": "24",
"id": "shellyplug-s-EF6165-0",
"idx": 1152,
"name": "5.2 TestShellyPlug",
"nvalue": 1,
"stype": "Switch",
"svalue1": "On",
"switchType": "On/Off",
"unit": 5
}
============================================

So it's both "nvalue" and "svalue1" changing in the json when switch is operated.

What would be the correct part in MqttMapper.json to make the new created device/switch function as wanted (as a switch)?
Part below doesn't work and throws erors ......

"5.2 TestShellyPlug": {
"topic": "domoticz/out/5.2 TestShellyPlug",
"type": "244", "subtype": "62", "switchtype": "0",
"set": {"payload": {"nvalue": "#"}},
"mapping": {"item": "nvalue", "default": "0", "values": {"Off": "0", "On": "1"}}
},

For an on/off switch, nValue is sufficient.

The wrong assumption is about the set part. You can't set domoticz/out to set a (remote) value. You should make a (more or less) complete message on domoticz/in topic, or use http API.

So, in any case, you have to remove the set part.

Next step depends on your need to set the remote switch from the local Domoticz. If you only need to get the (remote) state, that's over.

If you also want to set it from the local Domoticz, then you have to create a local push button to turn the remote switch on, probably using Domoticz http API, and another (local) one to turn it off.

It's a good idea to separate "state" device and "command" device, to avoid endless loop (you change state from local, which is sent to remote, remote sends a change on domoticz/out, which changes the local state, which is sent to remote ...)

Thanks for your explanation.
I understand the misconcept I tried to build (sending to domoticz/out).
So I have to build something else.

But still .... if I only want to read (and see) the status of the remote switch .....

"5.2 TestShellyPlug": {
"topic": "domoticz/out/5.2 TestShellyPlug",
"type": "244", "subtype": "62", "switchtype": "0",
"mapping": {"item": "nvalue", "default": "0", "values": {"Off": "0", "On": "1"}}
},

doesn't work.
New mistakes made?

If you want to switch a switch on another domoticz server you can use action scripts. Instead of the bash script as example below use the http json API command eg for the On Action use (change IP, Port and IDX to real values)

Code: Select all

Thanks again for this part.
Will add it to my knowledge base.

For the part of switch (above) I decided to talk MQTT directly (because it's also MQTT-enabled) to it.
And not in the strange way via domoticz/out of my other Domoticz.

So now I have functioning:

"TestShellyPlug": {
"topic": "shellies/shellyplug-s-EF6165/relay/0",
"type": "244", "subtype": "73", "switchtype": "0",
"set": {"topic": "shellies/shellyplug-s-EF6165/relay/0/command", "payload": "#"},
"mapping": {"item": "", "default": "", "values": {"on": "100", "off": "0"}}
},
MQTT-mapper is connected to the other broker as you understand.

Why this?
I want to keep my Thermostat-RPi-Domoticz clean.
And keep all power-metering on my Energy-RPi-Domoticz.
Now I can switch things off/on from the first while keeping the switch and power meters itself talking to the second.
So my shelly-plugin is only needed on the last one.

And more ...
It's interesting to experiment with your mapper-plugin!
Well done!

Willem

A little bit off topic (and perhaps I asked this before): why all these seperate Domoticz instances? You can relay the energy data directly to your main RPi,....

What do you mean by "doesn't work"? Any error messages (which ones?), just do nothing, ...?

I'm trying to add a dimmer, but though I'm able to set de dim level of the device, MqttMapper can't map a received level.
Here's my json entry:
"set-speed": {"topic": "fan/cv_booster/speed_level/state",
"type": "244", "subtype": "73", "switchtype": "7",
"set": {"topic": "fan/cv_booster/speed_level/command", "payload": "#"},
"mapping": {"item": ""}
}

setting the level manual trough a mqqt sub command, will also send a new message in de ../state topic with a value from 0 to 100. But this value can't be mapped to de domoticz device:
Bad mapping for ...

Setting the level on de domoticz device towards de mqtt device on the ../command topic works very well.

I solved this Quick 'n Dirty for now by adding "valueToSet = readValue" right within the "else" of the "Bad mapping" error exception.

Maybe someone can point me in right direction to solve it correctly.

Code was not able to support dimmer. This just changed with last version, available since few minutes.
Could you update and try it?
TIA.

Let's try with last version.

Note: you're not a programmer, but you found where the problem was ;-) In fact, nValueToSet was effectively not set if switch was not an on/off one.

Thanks FlyingDomotic,

This works!

BTW. I'm more of a wannabe programmer, I do know my way around in making small shell scripts. But if it gets any bigger, every little change or added code is build upon trial an error (and based upon code from others).

I made a device with a setpoint and I can change the setpoint manually

Code: Select all

   "HBVK - Ventilator snelheid ref": {
        "topic": "Voorkamer/fan-speed-ref",
        "options": {"ValueMin":"0","ValueMax":"100", "ValueUnit":"%"},
        "type": "242", "subtype": "1", "switchtype": "0",
        "set": {"topic": "Voorkamer/fan-speed-ref"},
        "mapping": {"item": ""}
    },
But if I change the setpoint (50) in a dzvents script the ondevicemodified is triggered and the old value (79) is send
2024-02-02 22:15:00.237 HeatBooster: 004/HBVK - Ventilator snelheid ref, Voorkamer/fan-speed-ref: Command: 'Set Level', Level: 50.0, Color:

2024-02-02 22:15:00.237 HeatBooster: MqttClient::Publish Voorkamer/fan-speed-ref (50.0)
2024-02-02 22:15:00.240 HeatBooster: onDeviceModified 004/HBVK - Ventilator snelheid ref, Voorkamer/fan-speed-ref, sValue=79.0

2024-02-02 22:15:00.240 HeatBooster: MqttClient::Publish Voorkamer/fan-speed-ref (79.0)
How can I prevent that the old value is send?

Hello!

I just copied/pasted your definition in a json file, and tried it.

I tested by changing target temp from 3.0 to 4.0 with GUI, and then to 19.0 by a LUA script. Here's the log:

AS you can see, I don't have the "onDeviceModified" you got. How do you set the target temperature?

I see that you use LUA script, so I tried that also and that is indeed working fine.
The dzvents script I use:

Code: Select all

return {
	on = {
		timer = {
			'every minute',
		}
	},
	execute = function(domoticz, timer)
		domoticz.devices(183).updateSetPoint(25)
	end
}
May be a Domoticz issue?

However when I use it with another setpoint device not related to MqttMapper the dzvents script is working fine
