# 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
|
||||
```
