Plugin flowmeter¶
Purpose¶
This plugin allows to manage the consumption or flow rates by calculating the hourly, daily, monthly and annual flow for some counters like water or electic meter, rain gauge. Some counters can be reset to 0 during their operation, this plugin will allow to take account of this case.
To work the plugin will listen to the device counter already existing in other plugin and update flow rates at each counter increment.
Plugin configuration¶
No specific configuration
Create the devices¶
There is only one type of device: flowmeter.
It is possible to create the devices in the “Advanced” tab.
A list of choices will offer you to search the counter sensor in the devices already present in Domogik.
This list will only show the sensor type:
["DT_Number", "DT_Counter", "DT_ActiveEnergy", "DT_kActiveEnergy", "DT_kMeter", "DT_VolumeLiter", "DT_VolumeM3"]
Warning
After adding a device, it will be necessary to restart the plugin. For some unknown reason, the “update.device” self.register_cb_update_devices() callback does not work with self.add_mq_sub() function.
Device parameters configuration¶
3 parameters are needed for a domogik device creation …
| Key | Type | Description |
|---|---|---|
| counter | Number | Counter Domogik sensor ID |
| formula | String | Formula applied to the difference, Example: VALUE * 0.2794 |
| periodic | Boolean | Set to false if counter does not have a periodic update |
Sensors details¶
Each device has 4 sensors:
- flow type: Update every counter change
- hourflow type: Update withe the sum of flow sensor every 5mn for a last hour period
- dayflow type: Update withe the sum of flow sensor every 5mn for a last day period
- monthflow type: Update withe the sum of flow sensor every 5mn for a last month period
- yearflow type: Update withe the sum of flow sensor every 5mn for a last year period
All sensors have a DT_Number datatype by default, You can change this type in the Sensor Configure page to see this information in the graphs.
Start the plugin¶
You can now start the plugin (start button) and use the created devices.
After a few run time of the plugin, you will see the result in the Advanced tab.You can see a summary for each flow sensor by period:
The View all button will display all hour,day,month and year histogram. it can take some time that while there is a glyphicon link for each pariod.
- Hour flow histogram
- Day flow histogram
- Month flow histogram
