My Project—
Climate controller’s for my 2 heat pumps. Both are Trane, air-air with electric resistance aux heat. After much research, the ESPHome Thermostat Climate Controller seemed to be the best fit for my goals.
My full error message—
bmp280::BMP280Component doesn’t inherit from sensor::Sensor
My project had been working for a few days with no real problems. Although I would be making some modifications to the code for my personal situation, but only after I tested the basics thoroughly. I was using one of my existing Govee H5075 Hygrometers from Home Assistant for temperature readings. Being a battery powered, bluetooth device, the polling updates were not as often as I would like. I then decided to use a local hardwired sensor for faster response and so the controller would still function, should I lose connectivity to Home Assistant.
This is the working code that I tested for several days with the Govee sensor:

I had a few BMP280’s on hand so I tested one of those for a few hours using this code. I removed the existing sensor code, the climate component and added the BMP280 code:
captive_portal:
i2c:
sda: GPIO4
scl: GPIO2
scan: False
sensor:
- platform: bmp280
temperature:
name: "Upstairs_Temp_Sensor"
oversampling: 16x
id: upstairs_temp
address: 0x76
update_interval: 30s
# Use the blue LED in the device as a status LED, which will blink if there are warnings (slow) or errors (fast)
status_led:
pin:
number: GPIO5
inverted: True
# Four relay outputs, exposed as switches in Home Assistant so I can see their status
switch:
- platform: gpio
pin: GPIO16
name: R-Valve # Relay 1
id: r_valve
- platform: gpio
pin: GPIO14

id: compressor
- platform: gpio
pin: GPIO12
name: Aux-Heat # Relay 3
id: aux_heat
- platform: gpio
pin: GPIO13
name: Fan # Relay 4
id: fan
After testing this for a few hours, I added back the climate component and that is when I got the error message. Both in the ESPHome code editor and in the complier logs.
I substituted both BME280 and BME680 sensors but continued to receive the same error. I then tried using a Dallas sensor and did not receive an error with that code. I don’t have a Dallas sensor on hand to test and I had planned to use a BME280 in my final product. Here is the Dallas code that I used, without error:
dallas:
- pin: GPIO2
sensor:
- platform: dallas

This is the full code with the BMP280 sensor that resulted in the error code:

I have done quite a bit of researching, and if I did find a solution, I certainly didn’t recognize it… 
Best regards to all…
