IoT Powersensor #2
For the main power distribution in my house, I also build a powersensor. The basic idea is the same as for this sensor. But the electric meter is already build into the distribution cabinet, so this power meter uses the so-called S0 bus of the power meter inside the cabinet.

IoT Powersensor #1
This is my first power/voltage sensor I've build. It is based on an commercially available powermeter from B+G E-Tech. You can find them on eBay or their website. It provides a 90ms pulse for each Wh flown through it.
The line voltage is measured using a simple transformer and a circuit based on the schematic from OpenEnergyMonitor. The software to measure the line voltage is also from OpenEnergyMonitor embedded into my sensor framework.

Arduino Library for AD7887
Based on the code from Makis, SV1AFN I have created a small library to access the AD7887 ADC converter. The library is pretty simple to use.

IoT System management
My MQTT server also has some basic systems management capabilities - means the MQTT server can emit the following data to the MQTT broker:
- CPU temperature
- Power supply temperature
- Average CPU load
- Uptime of server

IoT MQTT Infrastructure
Since the beginning of my home automation project I made several tests to choose the right platform and right controller. I've done test with various sensor technologies etc. etc.
Most of the articels can be found in the Arduino category.
One decision was, that my webhost should be the main datastore for all data measured. With this decision, I've started to build a data collection and distribution infrastructure. The complete setup consists of two major components:
These components are detailed further down the page.
