MySensors DST temperature in Fahrenheit

Petjepet

I’m struggling to have my Dallas Temperature node to report metric values (Celsius).
It now sends out imperial (Fahrenheit) values to my gateway.

I started a discussion on the MySensors forum and referred to the plugin builder.
Can someone help me out on this?

@Petjepet It is definitely something which should be implemented as part of pimatic-mysensor, similar to what we did for pimatic-homeduino and pimatic-openweather in the past. The process is to raise a feature request so that users can upvote on this. If you’re lucky the feature gets implemented some time soon!

~~I’ll move this topic to feature request now! So, no action is required from you side.~~

Having re-read that sketch I realize it may be an configuration problem or possibly some bug.

Do you use the function in the mysensors sketch to determine if the gateway is set to metric?
I’m using this for a DHT sensor, and that one does report back in Celcius.

Have you set the mysensors plugin to metric? https://github.com/DheerajKhajuria/pimatic-mysensors/blob/development/MySensors-config-schema.coffee#L28

the sensor should ask for the config if in metric or imperial. Pimatic will send the value set in the plugin. https://github.com/DheerajKhajuria/pimatic-mysensors/blob/development/MySensors.coffee#L316

Try to clean the eprom of the sensor and re-upload the sketch.

My plugin is like this:

  "plugin": "mysensors",
  "driver": "serialport",
  "protocols": "1.5.1",
  "startingNodeId": 1,
  "driverOptions": {
    "serialDevice": "/dev/ttyUSB1",
    "baudrate": 115200
  }

Do I need to add an entry here to set the sensors to Metric?

I also had a question about not seeing debug info in Pimatic for MySensors. Is this also related to a missing entry in the plugin definition?

sweebee

Its by default metric so you don’t have to add it.

I also see no debug log of mysensors, but for homeduino i do. Don’t know why. Can’t find anything different.

Trying to re-upload the sketch and I get an error now (multiple libraries):

Why does Arduino manage to hold 2 libraries?
When a library gets updated it will be set in a User folder I guess.
Clearly you have by default duplicate libraries since the initial library is installed in the Program Files folder.
