It kind of amazes me that, in this day and age, email has turned out to be the lynchpin of security. Email as a 2FA endpoint. Email password reset systems. If email is compromised, everything else falls. They used to tell us not to put anything in email that you wouldn’t put on a postcard…how did this happen?
Also check that the switch is rated for motors. A lot of the switches I’ve seen have separate power ratings for resistive (lights) and inductive (motors) load, because of the power-factor or inrush spikes. https://www.getzooz.com/zooz-zen15-power-switch/ is Z-wave, but specifically for high-current motors.
