ESP32 DIY Weather Station MQTT Discovery Problems

Configuration
1

This is my first post, so I apologize in advance if it’s in the wrong place.

I couldn’t find a weather station, which handled APRS and Home Assistant, so I started this project. Plus it gives me an excuse to learn circuits and C++.

Home Assistant works great when I manually put the mqtt entries in configuration.yaml. (Except the time, but that’s another issue). I would like it to be discovered, so if I send a board to someone less technologically inclined it automagically works. Plus it’s the principle of figuring it out and learning something new.

MQTT Discovery - Home Assistant has gotten me most of the way. I’m probably overlooking something obvious that’s documented.

The original code can be found in the following link. I apologize for the code, it’s my first C++ program. (yeah I haven’t even done hello world). The config json is at the bottom of example_settings.h

I am getting timeouts from Mosquitto. I’ve tried increasing the keepalive to a bit over 5 minutes and still get it. I only need it to report every 5 minutes. I plan on eventually turning the wifi off between broadcasts to save on battery.
Client WeatherStation has exceeded timeout, disconnecting.
