Question: Using power button for HA calls

[Xitro01]

So this time not a bug, also not really a feature request. Just a question if something is possible.

Would it be possible to light the power LED when an entity in HA has a certain state? Also would it be possible to long press the power button when it has this state to change an entity in HA?

I have a cool idea with the lamp, but not sure if it is possible to pull off.

Thanks!

The LEDs of the front panel can be controlled individually, so it is possible to give the power button light its own functionality. For example, on my bedroom lamp, I installed a microwave presence sensor, and I power up the power button LED for 3 seconds when the sensor is triggered. This allows me to see the button in the dark.

Long press and a HA call are possible too. That's something I use too. Long press triggers a power off script, so I can turn off everything in the house when going to sleep.

[Xitro01]

That sounds quite like what I would like to achieve. After a certain time (9PM) I would like to have the power button lid if my "House mode" is "Default". If I long press the button "House mode" should go to "Night mode" (which turns everything off in my home) and that should turn the power LED off.

Do you have some configuration examples for me, to achieve this? Would be great, thanks in advance.

Sure thing, I'll share some stuff when I'm behind my pc. I will put my config in a config package on the GitHub repo, so anybody can use it for inspiration.

I have just gone through the upgrade procedure for the lamp configuration, so the config is now compatible with the latest releases of ESPHome and the bslamp2 external component. I have not yet created a configuration package yet. However, here's the configuration of my bedroom lamp for some inspiration. Note that I've got some local configuration packages for setting up WiFi for example, but I think you'll find what you need in here.

Can this issue be closed @Xitro01 ? Or do you need more help with this?

[Xitro01]

@mmakaay Sure, you may close the issue. Haven't been able to get this to work yet, but don't have a lot of time to fiddle around. I also found a completely other route to achieve what I would like.

[mmakaay]

Okay, feel free to come back to this issue if and when you get back to this idea.
