Template syntax for selecting entity of domain type switch from list?

[metawops (Stefan Wolfrum)]

I’m trying to get the name of the single one switch entity of a device and I’ve gotten this far:

So – for later automation ideas – I have the device name in a text helper, I can get the device ID I need for an automation but I need the one switch entity id from that device to be able to toggle it in the automation. I have currently three of these cool Ulanzi clocks, flshed with the Awtrix firmware and I’m trying to use one IKEA Symfonisk gen2 remote to control all three of these watches/matrix display.

But I’m a noob at templating and Jinja2 and don’t quite understand the link between the Jinja2 select/reject/selectattr/map/… commands and the HA specific attributes.
So the last line doesn’t work yet.
Maybe someone has an idea? Maybe @petro, the templating Ninja?!

UPDATE:
Ohhh nooo, I’m afraid, my whole idea of using a text helper that contains the current Ulanzi clock’s device id and use that in an automation goes bunkers:

Please don’t say I can’t use templates in an automation?

Device actions, triggers and conditions do not support templating.

Use the switch.toggle service. It will be a whole bunch easier too.

And stop using device automations.

Disappearing automations

I’m guessing you are using either device triggers, conditions or actions. This is one of the problems with using this simple method. Automations are only visible if all the devices they depend upon are available. It’s a big problem that you can avoid by not using device triggers, conditions or actions. There are always other triggers conditions and actions you can use instead. e.g. instead of a device turn on trigger use a state trigger. See: and For the actions, refer to the documentat…

Ahhh, thanks so much, @tom_l, I’ll rethink everything and try my best to be not dependant on device IDs!
