Default Light Temperature

ESPHome

Hey guys -

I am using a light flashed w/ ESPHome and I wanted to know if there was a way to set a default color temperature when i power it on as on the rare instances it loses power, it powers up to a super hash daylight white. Thanks

    # Ensure the light turns on by default if the physical switch is actuated.

on_boot: - see the esphome docs :slight_smile:

Hmm. Not sure I follow how this could solve my problem. If I understand how this works, I would have to have this trigger a light on event with the temperature set. That’s not what I want. I want the light to be off after a reboot (think power outage) but the next time it gets called to turn on have a specified temp. Part of the problem is that I call this light through the toggle service and using the hass UI.

Edit: feel free to tell me I don’t understand and that I should re-read the docs :wink: but my understanding of what I read is that it wouldn’t solve this.

I think I found the solution: “on_turn_on” from https://esphome.io/components/light/index.html#config-light. Somehow I missed this last time I checked as I was focussing on the cwww docs. Thanks

Here’s a blueprint I created to solve this for my Sengled zigbee bulbs. They only turn on to the previous state and don’t have a default turn-on value. If you need a default brightness/color (not color temperature then Default Turn-on Value is what you need.
