Tiers and capabilities

Two things decide what you can and can't do with Pixel: your tier and any capabilities you've been granted. Both are checked every time you run a command.

Tiers

Tiers are ordered: a higher tier can do everything a lower one can.

Tier	Who
Admin	Pixel's operators
Member	A paid Pixelbar membership.
Friend	A paid "friend of Pixelbar" membership.
Guest	Everyone who isn't listed. Being in the Discord server, or being known to Pixel, makes you a guest.

Pixel uses your Discord ID - a unique identifier assigned by Discord to identify you. This ID is per account across Discord.

/help lists only the commands your tier allows, and /whoami shows the tier Pixel has for you.

Your tier is wrong?

Ask a Pixel admin. Only they can change it.

Capabilities

A capability is a named permission for one person, for things that shouldn't reach every tier. A command that needs one checks your tier and the capability: both must hold.

Capability	What it allows
schedule-posts	Schedule messages and polls in channels you can post in, with /schedule.
spacestate	Set the space open or closed, with /spacestate set. Members only.
ha-lights	Change lights in Home Assistant, with /ha set.
ha-switches	Change switches in Home Assistant, with /ha set.
ha-doors	Unlock doors, with /ha open. Members only.
ha-admin	Act on any Home Assistant device, whatever its kind.

• Nothing gives you a capability by itself. Not your tier, not a Discord role, and not being an admin. An admin grants it to a person, and Pixel sends that person a direct message when it changes.
• Guests never pass. If someone goes back to guest, their capabilities stop working straight away.
• They're narrow. ha-lights doesn't reach a switch or a door.

Home Assistant devices

Each device has its own minimum tier to be used. Seeing a device and its state needs only that tier. Changing it needs the tier, plus ha-admin or the capability for that kind of device, plus an action that device allows.
