Hello! I'm working on a project to make my "dumb" AC smarter by using a NodeMCU to transmit IR codes remotely. I'd love to hide the NodeMCU inside of the AC to keep things tidy, and realized there's a 5v and Ground easily accessible. This got me thinking, why not tap into that 5v and power the NodeMCU without needing a second power supply? I'm curious if there are any reasons this might be a bad idea. The 5v is to power the control panel for buttons, LEDs etc. The only problem I was thinking is if the AC compressor causes a power surge, but it seems to handle that part for the panel, but is there anything else to be concerned about? Thanks in advance!
