Here is the community conversation I had when setting up Heimdall. You can see all the mistakes I made.
To set up the Sensor Virtual Device:
- Add a device, virtual device
- Give the device a name nd select an icon, I use the open door icon
- Select the device class, select Sensor class
- Select a capability, select Door/Window Open
That’s it. Then follow the thread above and you should be all good to go.
I have a gate and a garage door, and the garage has a side door as well. So even though I only need one output to open the garage door, I use both inputs to monitor the state of both doors. You can see here my garage door is open.
