A Telegram bot for monitoring spot prices of electricity. To sauna or not to sauna, that is the question.
The app pulls hourly spot prices for Nord Pool, and divides them into day (07:00-23:59) and night (00:00-06:59) segments.
Daily averages are calculated from the day segment only. Nightly prices are ignored.
The app adds electricity company margin, Finnish VAT, grid transfer fees and electricity tax to the spot prices, so all values shown are total prices per kWh.

npm run start
By default, when run locally, the program will do a dryrun, printing the HTML-formatted content of the messages instead of sending the messages to Telegram.
In order to send messages to Telegram, you'll need to setup a bot and a chat, and either disable the local dryrun, or deploy the program to AWS Lambda.
npm run build
npm run lint
npm run test
When running npm install, husky should setup a pre-commit hook, so these will be run automatically before each commit.
