[57north-discuss] ESP32 poor wifi, likely due shielding by a nearby ESP8266

[Wouter Piessens]

Good morning folks,

Yesterday I managed to move my weather station to the back of the garden
and at same time install Kevin's air quality sensor on the same mount.
Unfortunately, due to the design of the mount, the ESP32 in the weather
station is shielded in the direction of the router by the ESP8266 in the
air quality box.  Hence, the router is only seeing the air quality ESP8266.

Unless there are no other options, I will not rebuild the mount.  I wonder
if any of you know of any tricks to boost the wifi signal through hardware
or via software (micropython) for the onboard wifi antenna.  Moving the
wifi router does not seem to help.    Except for the ESP's, all my internet
connections at home use the 5 GHz bands or are wired.  But obviously the
tens of neighbours have likely hundreds of 2.4 GHz wifi appliances
disturbing the spectrum nonetheless.
Distance between ESP's and router: 20m horizontal, 2m vertical, with only a
window between them.

Any ideas?

Cheerio,
Wouter
