Hi!

I'm thinking of pairing two S210/220 switches to make a room with two separate lighting circuits work together to light as one unit. 

Presumably I could use the trigger of switching on the light to trigger the other light switch to switch on? 

If this was a local routine with a good connection, what is the likely latency? 

Also, I was going to pair this with a movement sensor, but I'd only want the lights to come on in the dark obviously... How could I do this? 

Thoughts were either pairing with a lux sensor or time based triggers... Tried searching on this but it's not clear what's possible. On the tapo app playing with two old smart plugs I can only seem to create really simple routines - is there a way of writing more detailed routines manually?

Thanks for any advice!
