A Python plugin for Domoticz that creates several devices for the HomeWizard Wifi Watermeter.

The HomeWizard Wi-Fi Watermeter is a device that can be placed onto your watermeter. By default it sends all of its data to the HomeWizard servers but thanks to its local API you can read the device locally too. With this plugin you can use Domoticz to read the meter and store the data without using your internet connection.

Domoticz uses Python to run plugins. Use the installation instructions on the Domoticz wiki page to install Python. When Python is installed use these instructions to install this plugin.

To access the data from the Wifi p1 meter, you have to enable the API. You can do this in the HomeWizard Energy app (version 1.5.0 or higher). Go to Settings > Meters > Your meter, and turn on Local API.

The plugin creates a total of 3 devices.

1. An watermeter that shows your daily water usage in liters and totals in cubical meters.
2. An watermeter that shows your current water usage in liters.
3. A Wi-Fi signal strength meter that shows the current signal strength from the Wi-Fi Watermeter.

The configuration is pretty self explaining. You just need the IP address of your Wi-Fi P1 meter. Make sure the IP address is static DHCP so it won't change over time. Also don't forget to turn on the local API in the Homewizard Energy app.
