I’m looking for a simple plug and play CO2 sensor that will work with Openhab. It must be able to be used in a high humidity condition. I have been looking at using a MH-Z19 CO2 Sensor with an Arduino and ESP8266, communicating data back to Openhab to control a relay and fan (possibly via MQTT). …

I have put some examples for the MICS-VZ-89TE here: GitHub - iot6466/CO2-Sensors: Code for accessing different CO2 sensors Here the things: Thing topic rbpt2 "mqtt-rbpt-2" { Type number : CO2 "CO2" [ stateTopic="/rbpt-2/VZ89/CO2" ] Type number : VOC …

Awesome find!! Thanks so much for sharing! That’s why I love the Openhab Community!

To be frank it isn’t CO2 but VOC. Then again, that’s usually a better measure for air quality to look after.

I’m looking at their products right now. It looks like they have some eCO2 sensors. I"m going to reach out to them and see what they offer. I believe this should work. I need CO2 or equivalent CO2 levels. This sensor should work. Either way, this is a great find and I think it should help out …

I have tested several sensors, the CCS801, the MICS-VZ-89TE and the MH-Z19, connected to an ESP8286 module running ESPEasy. All are working fine, I just had problem with the CCS801 because I did not proceed with the burn-in procedure properly. I prefer the MICS-VZ-89TE as it is working with the I2C…

I have code example for the Raspberry Pi and for the ESP8266/32 as module for the ESP Easy framework I can send you directly.

ehm, or you post it here for others to see. :stuck_out_tongue:

I am working since nearly 1y successfully with OH and am also interested in such CO2 sensors to extend my possibilities. This connection RPI/ESP8266/MICS-VZ-89TE needs advanced knowledge with soldering and programming as far as I understood, right? So this USB-stick seems to be the better out-of-the…

I am using this one: Amazon.de It is connected to a RPI, running a Python script that queries the sensor every X seconds and uses the openHAB REST API to report the values. Script: openhab-config/co2mon at master · KristofRobot/openhab-config Various OpenHAB configuration files. Contri…

Thank you for the reply! I’ll check the MICS-VZ-89TE out as well.

Do you have any code examples?
