SHTC3 plus CCS811 on ESPHome fails to read temperature

by BatsIhor on Sun Jul 05, 2020 3:00 pm

Hi all,

I have two sensors (SHTC3 and CCS811) connected to NodeMCU and configured with ESPHome, and it sometimes works, in most cases I get this message in logs and don't get any temperature info on my Dashboard:

[E][shtcx:059]: Communication with SHTCx failed!

Restart helps sometimes but not always. I have two such a combos, for two of my rooms, and they both have the same issue.
Is there anything I can use to troubleshoot it?

Here is my config:
Code: Select all | TOGGLE FULL SIZE
sensor:
  - platform: ccs811
    eco2:
      name: "Master Bedroom eCO2 Value"
    tvoc:
      name: "Master Bedroom Total Volatile Organic Compound"
    address: 0x5A
    update_interval: 60s
   
  - platform: shtcx
    temperature:
      name: "Master Bedroom Temperature"
      unit_of_measurement: "°F"
    humidity:
      name: "Master Bedroom Humidity"
    address: 0x70
    update_interval: 60s

The SHTC3 does not handle re-starting well and will not reconnect via I2C unless you disconnect and then reconnect its power connections. This is obviously not ideal, however we are not aware of a better solution at this time
