Fan MQTT Switch with value_template

MoiZie · August 31, 2020, 8:33pm

I’m trying to use a MQTT controlled ventilator, which has different state and payload topics. The payload is a ‘cmd’ topic that must be called using ‘VENTMODE,LOW,0’ to set the ventilator to low. The state topic reports ‘1’ in the above case, 2 for middle speed, 3 for high, 11 for permanent low, 12 for permanent middle, 13 for permanent high and 0 for auto.

Now I’m trying to create a switch, which basically allows for toggling (for example) the middle speed, retains that state and changes the speed.
So far I have this:

- platform: mqtt
  name: "Ventilation 15 min middle"
  state_topic: "VENTILATION_GATEWAY/duco/Ventilationmode"
  command_topic: "VENTILATION_GATEWAY/cmd"
  payload_on: "VENTMODE,MIDDLE,0"
  payload_off: "VENTMODE,AUTO,0"
  value_template: >
    {% if value == 2 %}
      on
    {% else %}
      off
    {% endif %}
  state_on: "2"
  state_off: "0"
  optimistic: false
  qos: 0
  retain: true

Now, if I enable the switch, the speed of the fan goes to middle. But the switch immediately toggles off again. It appears it does not read the state topic correctly. I’ve tried other variations such as

  value_template: >
    {% if value == "2" %}
      on
    {% else %}
      off
    {% endif %}

But the switch will not retain the correct status. I’m doing something wrong, but not sure what exactly.

It’s unfortunate that mqtt.fan doesn’t allow more than ‘off, low, medium or high’ states or I would have been able to use that.

Hi,

I see your post is already a bit older, but I had some sort of the same issue and I solved it with making it all buttons.
See image below:

My dashboard code:

  - cards:
      - entity: null

        type: 'custom:button-card'
    type: horizontal-stack
type: vertical-stack

The top image is a button without function except showing the current state.
I’m using the custom Button Card to change icons into images.
My images are located in the folders as is described in the code.
If interested I can send them too.

Yeah if you would be so kind to send those?

Joost73 · March 31, 2021, 11:39am

Hi,

Can you also show me the config from the gateway where you configured the MQTT? And how you made the config in HA? i am struggling to get my DUCO running with the software from Arnemauer. I can control it from the Nodemcu but not via HA. https://github.com/arnemauer/Ducobox-ESPEasy-Plugin

Jozziej · April 5, 2021, 2:14pm

This is my config from the esp8266 gateway, just check that you also have the “Send to Controller” checked on the Devices Tab per device. This means that the data is being send over MQTT if configured correctly.

A nice tool to check your MQTT messages from your gateway or any other devices is MQTTfx
https://mqttfx.jensd.de/

Joost73 · April 6, 2021, 12:33pm

Thanks Jos, i missed that check box on " Send to controller" That did the trick!

Joost73 · April 6, 2021, 3:35pm

Hey Jos,

I have MQTT data now, but i still can not make it work in HA. Can you share me the sensor or mqtt related data how you configured it in HA?

Thanks in advance.

For the images I need to send them to your email if needed

Jozziej · April 18, 2021, 6:56am

I also have a gauge card to see the CO2 measured by the wired switch in the living room

type: gauge
entity: sensor.duco_co2_ppm_meter
min: 0
max: 1200
severity:
  green: 0
  yellow: 800
  red: 1000

To see any values in ESPEasy you need to put in the CO2 plugin and device id at 3, that’s my wired switch at least

TheCosmicGate · June 1, 2021, 7:33am

Hello @Jozziej could you send me those pictures ? And did you maybe DIY-ed the Duco USB cable ( to use together with the Duco software ) So i can read / use the software and try to look for the correct external sensor node ( now just tried the - trial and error- method, without any result)

Jozziej · June 1, 2021, 7:53am

Hi Pim,

Sure!
Send me a PM with your email.

You have to use a CP2102 instead of FT232 which I you used.
The Duco software looks for the CP2102 chip, I just changed the hardware name.
If you want access for Service use the password “Stella”

leeyuentuen · July 26, 2021, 10:51am

Hi Jozziej,
is it possible to share the images?

Jozziej · July 26, 2021, 4:17pm

Sure!

Send me a PM with your email

arjan-io · June 5, 2022, 3:33pm

Het is een oud topic maar zou je deze icons ook aan mij kunnen sturen @Jozziej ?

Ik probeerde je al te PMen maar dat lukte niet…
