How do you restart the device manually?

I have two devices from Athom with ESPHome installed.

3 gang switch
Switch relay

Both go offline for no reason, maybe due to EMI from a hairdryer.

Only the second one returns in a few minutes, while the "3 gang switch" remains offline.

I cannot restart it in any way other than power down my whole light section of the apartment at the breaker box. How can I restart the switch without going into a full blackout? Or can you please add a fallback option for this into: https://github.com/athom-tech/athom-configs/blob/main/athom-sw03.yaml
