Are these devices 220 VAC and less than 30 Amps? If so you may want to consider using the ELK 9200 Heavy Duty Contractor https://www.elkproducts.com/product/heavy-duty-relay-contactor-9200/ to control these devices. The ELK 9200 operates on 120 VAC but can switch up to 220 VAC @30 Amps using an Appliance Module or any other means to switch the 120 VAC.
Universal Devices has an app to control the M1 using a Voice Assistant Platform https://www.elkproducts.com/m1-integration-partn/universal-devices/
Or may want to review the Ness Automation Bridge (ELK p/n 101296) https://www.elkproducts.com/product/m1-automation-bridge-101296/
