How this rating comes about
Home Assistant calculates the rating itself: every add-on starts at 5, and each right it asks for or gives up moves the number. The same calculation runs here, on the configuration the add-on ships.
| Starting value of every add-on | 5 |
|---|---|
| Reached through Ingress, so no port of its own | +2 |
| May command the Supervisor (role: manager) | -1 |
| Shares the network of the host | -1 |
| Result | 5 / 8 |
A high number does not mean the add-on is good, and a low one does not mean it is dangerous – a backup add-on has to reach far into the system to do its job. The number says how much it is allowed to do, and the list above says what exactly.
What the add-on is allowed to do
- Uses the host network
- Supervisor role: manager
