Yeah there are lots of multi sensor projects on internet; this one also had bits, pieces etc. from other projects. Was looking a way to implement ESPHome on my HA installation and i needed a light sensor. You can find much better designs and circuits online, however i wanted to share this here for the desperate…
What you need:
- Nodemcu v1.0
- AM2302 or DHT22 Temperature/Humidity Sensor
- TSL2561 Light Sensor
- RGB Led
- 128x64 OLED Display

Box work (Tried to do it cutting acyrlic, failed miserably):
ESPHome Code:
esphome:

platform: ESP8266

wifi:
ssid: "XXXXXXX"
password: "XXXXXXX"
# Enable fallback hotspot (captive portal) in case wifi connection fails
ap:
ssid: "Esp Multi1 Fallback Hotspot"
password: "XXXXXX"
captive_portal:
# Enable logging
logger:
# Enable Home Assistant API

3D Box:

Couldn’t print the 3D box, neither have 3D printer, nor an online print facility. So burning and making holes on a plastic box, it came out horrible; but hey it’s working for my first project
