This product wouldn’t work, it is based on WiFi data transmission. To make it work with FH you need something that’s transmitting data on zigbee or z-wave networks.
I bought five IKEA “Inspelning” for use with Futurehome yesterday but will not be able to test in a while. I expect them to work out of the box as they are Zigbee. Jolly cheap and IKEA zigbee is known to be quite well behaved which makes me quite confident they do the job.
I have Aqara smart plugs running with energy metering now. Works well but cost about twice as much.
