New plugin pimatic-mqtt

---

@Rene-Arts Hi.
Although I am now in the stage just before the laying of cables in Flat1
Yes, I watch it
I’m using now H801 in the kitchen with PIR.
I used MqttSwitch:

    {
      "topic": "mh/ff/kitchen/dimmer/cmd",
      "onMessage": "pwm,15,1023,2000",
      "offMessage": "pwm,15,0,2000",
      "id": "cabinet-light",
      "name": "Cabinet light",
      "class": "MqttSwitch"
    }

You can also use dummy dimmer:

    {
      "id": "test-dimmer-with-transition",
      "name": "Test-dimmer-with-transition",
      "class": "DummyDimmer"
    }

    {
      "id": "test-dimmer-rules",
      "name": "Test-dimmer-rules",
      "rule": "when $test-dimmer-with-transition.dimlevel changes then publish mqtt message \"pwm,15,$test-dimmer-with-transition.dimlevel,500\" on topic \"mh/gf/lab/dimmer2/cmd\"",
      "active": true,
      "logging": true
    }

Value need to be converted for dimmer resolution. $test-dimmer-with-transition*1023/100 in this example.

ESP Easy newly used status topic for changes.

mh/gf/lab/dimmer2/status {
"log": "GPIO 15 Set PWM to 23",
"plugin": 1,
"pin": 15,
"mode": "PWM",
"state": 23
}

I guess I’ll have to deploy something like msg template for all devices.

Thanks, that might give me a temporary solution. Also just got an idea to use the Rules in ESPEasy.

Hi I am getting more and more into the MQTT business and I am beginning to like it (a lot)

However maybe I am overlooking something simple but I do not see how I can do it in a simple way.

I want to control my thermostat by MQTT (OTGW). I can receive the setpoint from the thermostat by “events/central_heating/otmonitor/setpoint” this works OK.

I have added a variable input device for setting the temperature. No problem to create a rule and to send out the MQTT message to the OTGW with the new setpoint “actions/otmonitor/setpoint”.

But the “events/central_heating/otmonitor/setpoint” can be set outside pimatic as well. How do link this value to the parameter used in the variable input device? As the MQTT value is not a parameter and I do not see how I can use or monitor the value in a rule?

Could somebody give me a hint.

And I know there is a seperate plugin for the OTGW but I am not satisfied with that as I have some socket losses, etc…

I think this is not possible.
I plan to add input devices to MQTT module.
Unfortunately, I have little time.

@wutu Ok clear to me I will wait and see!

@fennsen Please do not create duplicate posts. I am sure @wutu or may be some other user can help you further.

I’m playing with the plugin, but I can’t get something to work, probably due to some inexperience with this plugin.

I have a ESP that is publishing to a MQTT broker running on my Pimatic server. The MQTT plugin is connected to the broker (“info [pimatic-mqtt]: Successfully connected to MQTT Broker mqttbroker”).

I have created a MQTTSensor device, according to the howto this should be able to grab data from a flat json object published to the topic.
Unfortunately, it doesn’t get any data and stays “Unknown”. I have played with changing the type from number to string, or adding quotes around the value in the json object, but all without any luck.

To rule out a issue with the json object the ESP publish to a second topic with just the value. Unfortunately this also stays “Unknown”.

Running a mosquitto client to make sure the data is pushed into the topic:

 mosquitto_sub -h 192.168.2.121 -p 1883 -v -t /#
/electra { "T1":"1904618","T2":"2226285","L1":350,"L2":279,"L3":27,"Total":676}
/t1 1904618

Config of both devices:

    {
      "brokerId": "mqttbroker",
      "attributes": [
        {
          "name": "T1",
          "topic": "electra",
          "type": "string",
          "messageMap": {
            "test": ""
          },
          "acronym": "T1 stroom"
        },
        {
          "name": "T2",
          "topic": "electra",
          "type": "number",
          "messageMap": {}
        },
        {
          "name": "Total",
          "topic": "electra",
          "type": "number",
          "messageMap": {}
        }
      ],
      "xAttributeOptions": [],
      "id": "electra",
      "name": "electra",
      "class": "MqttSensor"
    },

    {
      "brokerId": "mqttbroker",
      "attributes": [
        {
          "name": "electrat1",
          "topic": "t1",
          "type": "string",
          "messageMap": {}
        }
      ],
      "xAttributeOptions": [],
      "id": "electra-t1",
      "name": "electra-t1",
      "class": "MqttSensor"
    }

Can someone give me a hint in what corner to search for my error?

UPDATE: Got it working, I need to use the slash in the topic name : "/electra"
Works like a charm

@wutu great will test it soon!

Hello, is it possible to use the mqttdimmer- device with ws2812b led’s?

Hello. Not directly. But some WS2812 control softwares can be controlled using MQTT commands.
For example, I use ESP8266 with Melvanimate and I drive it from Pimatic using the mqtt protocol. Also, McLighting looks interesting.
You can find another one here: https://github.com/search?l=Arduino&q=ws2812+mqtt&type=Repositories&utf8=✓ or https://github.com/search?utf8=✓&q=neopixel+mqtt&type=Repositories

@wutu thanks for fast replay.
It was nice to conect pimatic over mqtt to sonoff with tasmota firmware, to control ws2812b led’s.
Is there also a example anywhere?

Something has been discussed here. I use ESPEasy for Sonoff products. It is much more versatile and I do not have to learn to use other software. ESPEasy can do much more than Tasmota.

@wutu said in New plugin pimatic-mqtt:
Sorry for next question. 😊
Can I send mqtt-commands to ws2812 control from pimatic to a ESPEasy-device?
