Check Nordpool energy prices and send thermostat tresholds to Home Assistant

Gets day-ahead prices from Nordpool

Installation

npm install nordpool-hass
cd nordpool-hass
cp config-sample.js config.js
$EDITOR config.js

Configuration parameters:

area: Set the area where you want to follow the prices. You can see Nordpool/Elspot areas at http://www.nordpoolspot.com/maps/ Currently the active areas are BERGEN, DK1, DK2, EE, ELE, FRE, KR.SAND, KT, LT, LV, MOLDE, OSLO, SE, SE1, SE2, SE3, SE4, SYS, TR.HEIM and TROMSØ
currency: Choose either DKK, EUR, NOK or SEK
maxHighHours: If you use IFTTT to turn off heating when the energy price is high, you may want to limit the time your heating is off. If you set the maxHighHours to 3 and the energy price will be above your highTreshold for 7 hours, only the 3 most expensive consecutive hours will be triggered. Set to 24 if you want triggers for actual events.
maxLowHours: Same as maxHighHours but for hours below lowTreshold. If you want to turn some appliances on when the price is lowest, but don't want or need to have them on for too long, setting maxLowHours to 2 will select the two cheapest hours from every cheap streak (consecutive hours when the price is below lowTreshold). Set to 24 if you don't need limits.
veryLowOffset: Temperature offset when the price is very low.
lowOffset: Temperature offset when the price is low.
highOffset: Temperature offset when the price is high
veryHighOffset: Temperature offset when the price is very high
hassPassword: API password to Home Assistant
hassUrl: URL to Home Assistant. Remember the slash
hassSensorName: Name of the sensor

Start script will run PM2 to keep the script running.

npm start

Will create a sensor on Home Assistant server with the name from hassSensorName, e.g. sensor.thermostat_treshold.

Enjoy!
