Hello HA community,
I've recently gotten more into ESPs and electronics in general and just wrapped up my first little project: An indoor environment sensor using an ESP32 WROOM 32D and a BME280 temperature/humidity/pressure sensor and a BH1750 light sensor. After testing and validating the correct readings and connections on a breadboard I soldered the components together and designed a small enclosure to 3D print and house all the electronics. Here comes the dilemma: the temperature is considerably wrong (by about 2°C at times), which is something I was aware might happen.
The ESP wakes every 50 seconds to take a measurement, send it to MQTT and then goes to sleep after 10 seconds.
I have included some air vents in the box to at least get some fresh air into there, but I guess it is not enough. What is something that I could change (either about my box's design, or something on the electronics end (more efficient / less power hungry ESP?).
