Please execute the following commands to get the permissions.
$ snap connect energy-tools:hardware-observe $ snap connect energy-tools:home $ snap connect energy-tools:mount-observe
Connecting ':home' interface allows it to read/write files under home directory. Connecting ':hardware-observe' interface allows it to get the hardware information. Connecting ':mount-observe' interface allows it to check the system disk.
energy-tools needs those permissions to do the work.
If you install energy-tools by Ubuntu Store, there are some buttons to enable those permissions.
