Sends notifications to a LINE channel when electricity (denki) price is gets high or low.
I gave up making a LINE account public because broadcasting messages on LINE is costy.
So you need to prepare infrastractures like LINE account etc by yourself.
A scheduled function on Cloudflare fetches electricity prices from an external API every 30 mins (You can customize the frequency if you want).
If the price is on alert (expensive) o cheap, it sends a message to a LINE channel.
Note that information from the external API only contains prices from Japanese electricity companies.
