homebridge-tibber-price v1.1.0

Homebridge Tibber Price

A simple homebridge plugin that will display prices from your Tibber account, in various forms. (See screenshot further down)

Accessory: Actual price

Shows the price, in the smallest denominator of the currency (öre, cents, etc). This accessory will manifest itself as a light sensor, since there is no "energy meter" accessory type in Apple Home.

The accessory will display cents as lux. Can be hooked up to automation rules.

Accessory: Relative price

Shows the relative price, in percentage across the day. Compares the current price with the highest point of the day. This accessory will manifest itself as a humidity sensor, since there is no "energy meter" accessory type in Apple Home.

The accessory will display %. Can be hooked up to automation rules.

Price graphing

The plugin can also generate a .png image, graphing todays prices (and tomorrows, if available). The image will be rendered at 1280x720 pixels. Rendering will be done by an https call to Quickchart.io

In order for this to show up in Apple Home in any meaningful way, you can utilise Homebridge Camera FFmpeg plugin to "stream" the image, as a camera accessory.

Configuring

Configure via the Homebridge Config UI.

But if you need to do it manually, here's a short description of the configuration properties: | Property | Type | Required | Description | |-----------------------------|---------|----------|-------------------------------------------------------------------------------------------------------------------------------------------------------------------------| | platform | string | YES | Should be HomebridgeTibberPrice | | accessToken | string | YES | Should be your Tibber API key | | homeId | string | no | If you only have one house/home in Tibber, you can ignore this. However, if you have multiple, you should enter your HomeId here, to get the correct price information. | | priceIncTax | boolean | no | Show prices with tax/vat included | | activatePriceGraphing | boolean | no | Enable price graphing (Saved as a PNG every hour) | | activatePriceSensor | boolean | no | Enable the "light sensor" used for current electricty price | | activateRelativePriceSensor | boolean | no | Enable the "humidity sensor" used for current relative electricty price |

Configuring ffmpeg camera plugin

Configure the camera via Homebridge Config UI, and enter this under Video Source:

-f image2 -loop 1 -s 1280x720 -pix_fmt yuvj422p -i <PATH_TO_HOMEBRIDGE_INSTALLATION>/.homebridge/tibber-price/price-chart.png

This works fine for me, but ffmpeg has a lot of configuration options, so feel free to experiment.

Don't forget to replace PATH_TO_HOMEBRIDGE_INSTALLATION with the actual location
