Automation to turn on a device for 1 hr

[mrrcomp]

hi
Looking for how to create an automation that will turn on a device for one hour if triggered .

For example if i turn on a plug A it should also turn on deviceB for 1 hour

what type of plug you are using?

what you are looking for is called inching

Adding "Inching" to ex-Sonoff ESPHome smart plug

Hi all! Recently I flashed one of my (many) Sonoff S26 smart plugs with ESPHome. Great fun - managed to do it by holding probes on the 4 contact points by hand One thing I missed from the Sonoff functionality was the idea of “inching” - where you can set a delay on the plug itself to turn off automatically. Yes, easy enough to do in HA itself, but having it built into the plug gives you confidence in case of network outage etc that it’ll definitely get turned off. Anyway after some…

How about an automation which will turn off deviceB when it has been on for an hour?

When the AC turns on, start a timer and make a second automation that turns the AC off when the timer has finished.

Or, less robust, make an automation with a for condition to check if the AC has been on (or “not off” for 1 hour, since the AC can be in fan, cooling or heating modes).

Two ways to achieve it:

1. within the automation action itself, using a Delay under “add building blocks”…and set it for an hour, and then add your ac turn off action

2. Using a timer helper. Then in the automation actions you can utilize a series of actions where: starts the Timer > use the “wait for trigger” building block and use the condition of the Timer state turning to idle > turn off ac

Advantage of 1) is its just simply easier with no helpers; but if HA is restarted during this delay action countdown, it does not continue. Option 2), as I’ve been told, if your HA restarts while the timer is running, it will continue once its restarted.
