# SEM6000 Python Library
|
||||
|
||||
SEM6000 is a energy meter and power switch with Bluetooth 4.0.
|
||||
|
||||
This library provides a Python module for these devices
|
||||
|
||||
## Run the example code
|
||||
|
||||
```
|
||||
$ git clone … sem6000
|
||||
$ cd sem6000
|
||||
|

## Collectd Plugin
|
||||
|
||||
You can find a Plugin for [collectd](https://collectd.org) in the `collectd`
|
||||
subdirectory.
|
||||
|
||||
Installation procedure (the target directory may be changed of course):
|
||||
|
||||
```shell
|
||||
# mkdir -p /usr/local/lib/collectd/python
|
||||
# cp collectd/collectd_sem6000.py /usr/local/lib/collectd/python
|
||||
# cp sem6000.py /usr/local/lib/collectd/python
|
||||
```
|
||||
|
||||
Add or adjust the configuration for your collectd’s Python plugin as follows:
|
||||
|
||||
```
|
||||
<Plugin python>
|
||||
ModulePath "/usr/local/share/collectd/python"
|
||||
LogTraces true
|
||||
Interactive false
|
||||
Import "collectd_sem6000"
|
||||
|
||||
<Module collectd_sem6000>
|
||||
Address "12:34:56:78:90:ab"
|
||||
SocketName "FirstSocket"
|
||||
ReadTimeout 30
|
||||
SuspendTime 300
|
||||
</Module>
|
||||
<Module collectd_sem6000>
|
||||
Address "ab:cd:ef:13:37:42"
|
||||
SocketName "ASecondSocket"
|
||||
</Module>
|
||||
# ...
|
||||
</Plugin>
|
||||
```
|
||||
|
||||
`ReadTimeout` and `SuspendTime` control what’s happening when a device is
|
||||
unavailable. If no value could be retrieved for `ReadTimeout` seconds, the
|
||||
plugin does not retry for `SuspendTime` seconds. After that, normal operation
|
||||
is resumed. This procedure ensures that an unreachable device does not block
|
||||
other devices (too often) in the current single-threaded architecture.
|
||||
|
||||
If not specified, `ReadTimeout` is 30 seconds and `SuspendTime` is 5 minutes.
|
||||
|
||||
Make sure that everything listed in `requirements.txt` is available to the user
|
||||
running collectd.
|
||||
|
||||
