Hi,
maybe someone with more experience of this sensor could help me out here. I have been running a CCS811 sensor on a Wemos D1 board for a couple of months now. Twice in the last weeks I’ve seen spikes like this in the readings (the jump in the graph is from a reboot when trying to fix the issue).
It takes a couple of hours to settle but eventually the levels are stable again.
I use temp and humidity from HA to compensate and I see the values getting updated in HA and in the logs from the AQ esphome.
The baseline is from a couple of months ago - maybe time for a re-calibration?
This is my relevant esphome config:
i2c:
sda: GPIO4
scl: GPIO5
sensor:
- platform: ccs811
eco2:
name: "CCS811 eCO2 Value"
tvoc:
name: "CCS811 Total Volatile Organic Compound"
address: 0x5B
update_interval: 60s
baseline: 0x99C4
temperature: temp
humidity: hum
- platform: homeassistant
id: temp
entity_id: sensor.arbetsrum_temp
- platform: homeassistant
id: hum
entity_id: sensor.arbetsrum_fukt
Any ideas greatly appreciated!
