I am attempting to connect a Sensair co2 sensor, a Sen55, and a Mics 4514 to a wesp32, the later revision. I have multiples of all components here and have swapped all out, one at a time to no change. I have tried one sensor at a time. The I2C devices are “not found” on either bus or on multiple dif…

The code I am using: esphome: name: wesp32-1-test friendly_name: wesp32-1 test esp32: board: wesp32 framework: type: arduino # Enable logging logger: level: VERY_VERBOSE # Enable Home Assistant API api: encryption: key: (key) ota: password: (pw) # Example configuration e…

I was in the middle of editing it. It should be fixed now

Both the I2C scans doesn’t find any devices, so I would start checking the wiring. I don’t have a wESP32 myself, but if I look at the pinout scheme at Hardware - wESP32 — Wired ESP32 with PoE I get the feeling that you are mixing up pinnumbers and IO definitions. In that scheme pin15 is the SCL and …

Changed code to, following the link you posted, which I hadn’t seen as all other things, and that page on the site, point to the product brief “for more details” which doesn’t include that table: esphome: name: wesp32-2 friendly_name: wesp32-2 esp32: board: wesp32 framework: type: ardu…

The Mics is now functional and is reporting, but the sen55 and the sensair is still not

So one off the problems is solved, now the next one. If I look at your YAML, you are using GPI033 twice, (for I2C and UART) and you suppress the message that can help you to identify this problem by using by the “allow_other_uses: true” statement. You should only use that statement if you are really…
