Prevent ESPHome to automatically start after power outage/upgrade?

ESPHome

I have a oil difusser that have ESPHome installed to control it.
My question is, everytime I upgrade or have a power outage the oil diffuser turns on and start to blow out the “steam”.

Is there a way so that it doesn’t turn on at upgrades or power outage and so on?

Most likely.
Post your yaml.

Just plain template switch, interesting…
I don’t know why it’s switching on boot, default restore should be off.
Try to add this to switch:
restore_mode: disabled

Yes, that did the trick.

Works now, It doesn’t start after I pull the power cable or after I do an update of the code.

Thank you so much.

You are welcome!
I wonder why Esphome toggles template switch on boot with default restore though…
