# 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
|
||
$ virtualenv -p python3 python3_venv
|
||
$ . ./python3_venv/bin/activate
|
||
$ pip3 install -r requirements.txt
|
||
$ python3 example.py
|
||
```
|
||
|
||
## 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.
