async def close(self)

Set the relay to its closed state.

{
  "display": "Unlock the Front › Door Lock",
  "command": "CLOSE",
  "deviceId": 307
}

async def getRelayState(self)

Returns the current state of the relay.

For locks, 0 means locked and 1 means unlocked. For relays in general, 0 probably means open and 1 probably means closed.

async def getRelayStateVerified(self)

Returns True if Relay is functional.

Notes

I think this is just used to verify that the relay is functional, not 100% sure though.

async def open(self)

Set the relay to its open state.
