Looking for a reliable comms link inside theatre space. Theatres often have a lot of WiFi traffic from nearby hotspots and audience mobile phones.
Just want to send the status of one to five buttons.
Is ESPNow a good choice?
Any examples welcome

Hi Anthony,
Welcome to the forum!!
I cant speak from a reliability standpoint but ESP-NOW is very easy and (I presume) has worked for over 300 clients at the same time:
I have some example code I can send through (micropython) if this looks good.
If reliability is key why not go for a cable?
Hey Anthony,
There may be a better choice than ESPnow depending on what you are looking to set up here. Does the project need to be portable, or is it a stationary device? Is there any reason that it has to be a Wifi based signal rather than another method of activation?
If we could get a bit more info on this one, I am sure that we could figure out the best way to get this fixed up.
Cheers,
Blayden
