#79445 I think I want to do a fairly straight-forward project which I think I can pretty much just copy from here:

I just want some lights to flash in certain ways/colours whenever my Pi sends a signal via Wi-Fi.

Can anyone advise how to determine whether I want ESP-01 or 02 or 03 etc? I only need three GPIO pins but I care about a) signal strength and b) power consumption (a is more important to me than b).

#79449 You're new? Get a NodeMCU or Wemos (b is much more important than a, believe me). :idea:

You've got everything running and know your way around the ESP: go for the ESP that fulfils your requirements (i.e.. you wouldn't be asking here). ;)
