Help me query API for HiveOS using HTTP and OpenHAB

Hi All

I want to send commands and retrieve information from the HiveOS API, but I need some help

I want to retrieve

- Hash Rate
- Power Usage
- Temperature

And I want to issue reboot/power off commands.

I need help constructing the statements to place them into automation rules on my OpenHAB Home automation server using JSON

Thanks
Krios
