I'm wanting to add a bunch of energy monitoring stuff so I can both track costs, and maybe implement automation to turn stuff on and off based on power costs and timing.

I'm using some TPlink based plugs right now which are like, fine, but I'm wanting to add something like 6 to 10 more monitoring devices/relays.

Anyone have experience with a bunch of shelly devices and if there's any weird behavior I should be aware of?

Assume I have good enough wifi to handle adding another 10 devices to it, but beyond that any gotchas?
