Troubleshooting

With the Visual Micro Serial Debugger, you can now connect the debugger to your ESP32 or ESP8266 over WiFi for a completely wireless debugging experience.

Combined with OTA Uploads you can work completely remotely from your project, allowing you more flexibility, and faster development as you can develop and debug your project in the environment it is meant for, instead of on your desk!

I've been working on a device that I can add to a car which will connect to Home Assistant / MQTT and allow me to determine whether a vehicle is at home/away as well as allow me to monitor the charge level of the battery.  Since we have a few cars, some are not driven frequently and if the battery levels drop too low, they won't start and if low enough, the battery can be damaged or even completely ruined.  I decided to try to design the circuit and have it created as an arduino D1 Mini 'hat' using EasyEDA to design the circuit and JLCBCB to create it.  Here is all the relevant information I've gathered for the project:

I've been looking for a reliable way to get outdoor temperature into Home Assistant for automation purposes.  I've been using openweather which gets the weather at San Martin airport, but the reported temperatures versus what the temperature actually is here can sometimes be off by more than 5 degrees.  This is a solution that I can mount outside and doesn't require any electricity to run.  I did end up moving to a remote mounted solar panel which was twice the size (and output wattage) as the original.  This allowed me to put the sensor in the gazebo in an always shaded, yet open to air location which is unlikely to be impacted by sun impacting the actual temperature readings.
