Internal Sensors for Domoticz
Step-by-step how-to guide install the Internal Sensors on Raspberry Pi with the latest Raspbian Buster image and Domoticz.
This how-to is part of a bigger series of Domoticz how-to’s on sancla.com!
As most know by now, the Raspberry Pi 4 has the reputation to run hot. Perhaps hotter then we want, even with an idle CPU with Domoticz… One way to resolve this problem is cooling this beast.
In my humble opinion, the Flirc passive cooling case has been the best accessory for the the Raspberry Pi 4 one could buy (and for only € 20,- it’s a bargin): https://www.tinytronics.nl/shop/nl/raspberry-pi/behuizingen/flirc-raspberry-pi-4-behuizing-aluminium-zwart
In this how-to we utilize this case and it has been running for over an hour at approx 40° Celsius with Domoticz, i-love-this-case!!
However, besides making sure your Raspberry Pi 4 gets proper cooling, it doesn’t hurt to monitor the temperature in Domoticz. Doing so also enables you to configure alerting if the temperature gets to high and cool down your Raspberry Pi with a big bucket of conductive water…..
This tutorial has been verified with:
- Running Domoticz installation with stable Raspbian Buster release and SSH access. See my previous post for a how-to:
- Domoticz Python Plugin Manager installed:
- Raspberry Pi 4 (MEM 2GB with 16GB sd-card)
- Raspbian Buster Lite 4.19, Februari 2020
- Domoticz Stable 2020.1 (compile date 22-3-2020)
Configuring internal sensors in Domoticz
In Domoticz, go to hardware and add a new device:
- Name: Raspberry
- Type: Motherboard sensors
- Data Timeout: 10 minutes
After a couple of minutes, the internal devices are starting to appear under devices. Click on the green button to enable the monitoring of the device. You can give it a any name you want, such as “Internal Temperature” for example:
The temperature of your Raspberry Pi is now visible in Domoticz under temperature. You can take the same steps for the other sensors should you wish to monitor them.
As shown in above image, you can configure “Notifications” for each enabled device. So you receive a notification if your Raspberry Pi is starting to run to hot:
