# Gasmeter
|
||||||
|
|
||||||
|
Collect volume and power data of gas meter and store them in InfluxDB
|
||||||
|
|
||||||
|
## Installation
|
||||||
|
|
||||||
|
```shell
|
||||||
|
make install
|
||||||
|
```
|
||||||
|
|
||||||
|
Default install location for the executable is `/usr/bin`. This can be
|
||||||
|
modyfied by changing the `PREFIX` variable.
|
||||||
|
|
||||||
|
```shell
|
||||||
|
PREFIX=/usr/local/bin make install
|
||||||
|
```
|
||||||
|
|
||||||
|
## Uninstallation
|
||||||
|
|
||||||
|
```shell
|
||||||
|
make uninstall
|
||||||
|
```
|
||||||
|
|
||||||
|
When `PREFIX` was modyfied for installation it needs to be changed for
|
||||||
|
uninstalling as well.
|
||||||
|
|
||||||
|
```shell
|
||||||
|
PREFIX=/usr/local/bin make uninstall
|
||||||
|
```
|
||||||
|
|
||||||
|
## Configuration
|
||||||
|
|
||||||
|
Default configuration file is installed in `/etc/gasmeter/config.json`
|
||||||
|
|
||||||
|
## systemd service
|
||||||
|
|
||||||
|
```shell
|
||||||
|
systemctl enable gasmeter.service
|
||||||
|
systemctl start gasmeter.service
|
||||||

```
