I’ve got two plugs in my eaves that connect back to 2 Intermatic dial timers located back in the garage, both wired with 12awg wiring. The circuit is for custom Christmas lighting which should draw around 1550 watts (not LED). Shelly relays are too small for the load and will not accept 12awg wiring anyway.

Would prefer something wifi and not z-wave or zigbee as everything I’m running in the home is wifi based except for a Lutron Hub for our interior switches.
