# HS110-Grafana
|
||||
Power monitoring of the HS100/110 smart plugs via Grafana
|
||||
|
||||
Library used for the control of the smartplug - https://github.com/GadgetReactor/pyHS100
|
||||
|
||||
How to install:
|
||||
|
||||
Clone the repo to /opt/pyHS100 and run install.sh
|
||||
|
||||
git clone https://github.com/Amadeaus-dll/HS110-Grafana.git /opt/pyHS100
|
||||
|
||||
chmod u+x /opt/pyHS100/install.sh
|
||||
|
||||
The script automatically (if requested) installs InfluxDB and Grafana and starts the export script for the smart plug. The only thing that needs to be created is the graph in grafana.
|
||||
|
||||
Script is tested on Debian 9
