Also had to rename the existing DEBUG consts to DEVMODE, so as to not
confuse the two. DEVMODE is meant for developers and cannot be enabled
on-the-fly, whereas debug mode is for users to check that the bridge is
working, MQTT messages are received etc.
Update logging is throttled to avoid spurious messages for uncoalesced
MQTT updates and motion sensors. On my network with 10 devices, an
update is logged every 1-2 minutes on average.
The exposes entry looks similar to a switch, except the type is a
"light" and it has `state` and `brightness`. Tested only on single
channel dimmers.
Also added a PercentageTranslator to translate between the HomeKit
`brightness`, which is a percentage, to/from an arbitrary numeric value
in Z2M.
encoding/json would refuse to implicitly cast the numbers into strings.
Currently we don't use these values, so let's preserve their type using
`any` for now.
An example is `keep_time` for occupancy sensors, where it's
[30, 60, 120] seconds.
