Measuring air quality using Bosch BME680 and AMS CCS811 – IAQ, TVOC, eCO2

BME680 on Raspberry Pi 3

Measurement of basic environmental data in our apartment – temperature and humidity is one of the most popular applications of commonly available sensors for Raspberry Pi (RPi), Orange Pi (OPi) and ESP8266.

Then we added ability to measure the SMOG otuside and inside and today we will deal with two new and very interesting air quality sensors.

Domoticz part 8 – Stable instance of Domoticz, 24/7/365 mode – high availability at home

As a result, a both fresh and advanced user finds himself in a situation where the system – ceases to work at all, or requires frequent restarts, or worse causes quick degradation of the main storage device – which is often (micro) SD card.

Is there a simple and effective solution to increase Domoticz’s availability on Raspberry Pi / Orange Pi?

Sure there is! But first – before you begin – make a copy of your (micro)SD working used in domoticz instance on your Raspberry Pi/Orange Pi.
CAUTION: We will perform operations that may lead to the loss of all data – so make sure you have a copy!

What will you need?

Software:

  • monit
  • rsync

Hardware:

  • harddrive either classic HDD or better SSD, small is OK from 32GB up to 128GB
  • heatsinks for Raspberry Pi/Orange Pi
  • USB 2.0 or 3.0 to SATA adapter – so we can connect the harddrive via USB port
