Hi,
I built a letterbox sensor based around a nodemcu and 3 laser beams to detect if anything is in my letterbox, system works well indoors but when I take it out to the letterbox it stops triggering. I’m assuming the wifi signal is too weak to convey data, its a little weird as HA can still maintain a connection and can see the sensors, they just dont toggle anymore…
The other weird thing is when I first installed it in my letterbox it worked perfectly for a couple of days.
So question is, assuming this is a wifi issue, is there a way to extend the range of a nodemcu wifi?
