This plugin for Indigo extends the Indigo Home Automation system with an interface to the Dutch Smart Meters which comply to DSMR (Dutch Smart Meter Requirements). The smart meter P1 interface must be connected to Indigo via a serial to usb cable. The plugin will parse both electricity and gas usage. This information is stored in an Indigo device and can be used from there. You can show it on a GUI or e.g. write smart decisions to max power usage only when the low tariff is valid.

The plugin can be found in the Indigo plugin store. Full documentation of this plugin can be found on my website.

Changes in this release

On newer macOS versions the handling of the serial port configuration seems to work a bit different than on my test machine. To understnd this I added more information on the dict received to the Indigo log. Next to that implemented validateSerialPortUI helper function. Needed to change the warning for not configured device to newly used field as well. The main loop is not changed; it is only the validatePrefsConfigUi function which needed a small change. Thanks to John Steenhuis for helping me testing! Thanks to the Indigo team for their excellent documentation.

First public release of this plugin


The plugin is tested with Indigo version 7.4.

Buy a cable which connects the Smart Meter RJ11 port to the USB port of your Indigo server. Note: not all cables seem to work with all Dutch Smart Meters. This cable can be found on the internet. A FTDI cable and an old RJ11 phone cable might work as well.

Optional if you want to make nice graphs you could install two other plugins: Tthe SQL Logger and [Karl's Plot Deamon[(http://www.indigodomo.com/pluginstore/71/)
