after some trial and error i was able to track down the issue i mentioned in my last video and the sensors are now working as intended.

  1. Are you using Deep Sleep on the ESP32? The sleeping current seems a little high. If it's the sensors, have you considered powering them from the ESP32? If they have a low enough current draw, you can power them with an I/O pin and toggle the output to turn off the sensors just before sleep. They may take some time to start back up, which will increase the on-time of the ESP32, so you'd probably want to balance the longer on-time against the savings. You could also just turn off the sensors that don't take long to start up (if any) if you're looking to save every little bit of power. Of course, with a year plus runtime already, the only real benefit at this point would be the ability to use a smaller battery.
