Control a water heater and ground source heat pump based on cheap hours of spot priced electricity

I replied to the other thread where you asked about the ECMA script issue: How can I get my ECMA scripts working on openHABian? - #6 by masipila

I’ll also update the comment marked as the solution so that it mentions that the file permissions must be correctly set up.

Sorry for the inconvenience, hopefully this helps a bit and you’re able to make some progress.

Cheers,
Markus
