Shelly relays for energy monitoring (forum.uncomfortable.business)

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?

I'm running six Shelly Plug S and all working well with Home Assistant, but I could definitely play a bit more with the data it's drawing from them. Only issue to date was that I bought a new clothes iron and it would trip the plug as it was over the 2.5 kW the plug is rated for, might just be something to keep in mind. The in-wall relays may go higher, I'm not sure.

Yeah the plan was for the in wall relays. I'm in the US and if I read the specs properly they'll do 16a at 120v, which is also where my breakers would trip anyways so probably shouldn't matter.
