That's interesting. I am using an ESP32 dev kit too which monitors light level, temperature, humidity and soil moisture. That runs fine without any boosting but is quite sensitive to orientation. Another parameter I monitor is the RSSI signal. I then output that as a PWM signal to one of the outputs. I monitor it with a moving coil meter and series resistor. That signal is updated once a second internally and allows me to get a reading of signal strength as I change orientation. With the dev kit, orientation doesn't matter. Thanks for your input.
We have a lot of ESP32 devices deployed with a similar configuration.
Our biggest issue is when WIFI isn't serving the 2.4gHz nicely and the devices don't connect. And it's hard to troubleshoot over the phone. (Anyone have ideas for this let me know. We have user try personal hotspot which is an end-to-end indicator.)
Anyway check your extended that it's using 2.4.
