I want to control my curtains remotely. The hardware part is almost done. It consist out of a nodemcu, Hbridge motor controller, optical sensor (to count the motor rotations) and a geared down motor connected to the curtains. Hardware-wise it works. Now I need to create the software.

I want to access it on the devices tab, and adjust a percentage (just like controlling a light brightness) that correspond with the position of the blinds (0% fully open, 100% fully closed). Anyhow, playing a bit with the library, I think access to the attributes of the device is only available inside the flow charts? Am I correct?

Do I need to connect it through a virtual device which is linked through flows, or is there a direct way?

I would think that it should work if you give your device the class `curtain`, and use the `windowcoverings_set` [capability](https://github.com/athombv/homey-arduino-library/blob/master/docs/usage.md#capabilities) to set its position.

Something like this:

```auto
Homey.setClass("curtain");
Homey.addCapability("windowcoverings_set");
...
Homey.setCapabilityValue("windowcoverings_set", position);

```

However, I haven’t done anything with Homeyduino for a while, nor do I have controlled curtains, so not sure if those will be shown in the devices tab as you wish. If not, a (rather crude) fallback could be to use class `light` and capability `dim` (which also is a percentage).
