Reset light when deleted from the API

[ebaauw]

The Hue bridge factory resets a light, when the light is removed from the API, through a DELETE of the corresponding /lights resource. I think the deCONZ REST API plugin should do the same, especially for Hue lights, that don't support a power-on/off sequence to reset them.

Sniffing the Hue bridge, it sends a ZDP Leave Request:

The bulb responds with a ZDP Leave broadcast:

Hm, wouldn't it make sense to implement that for all routing devices (I know not all might support it)?

[ebaauw]

Maybe. I haven’t checked whether the Hue bridge sends anything when deleting a /sensors resource. Preferably, any device (that supports it) should be reset. I don’t know ZDP too well, in particular whether end devices are supposed to react to a Leave Request.

[hellcry37]

up for this, it has my vote

[Smanar]

But if the device don't support this feature, what we can have as problem ?
For me it will work or not, but I don't imagine a problem we can have if the device don't support the command
And I think I know another manufacture that use this feature.

Well, as I see it, we wouldn't have a problem at all. If the device supports it, all good. If not, you most likely receive an unsupported command response and that's it, nothing happens.

I m thinking same, it can only be good (or useless).

I'll be bloody damned! Checking the code, it turns out this has already been implemented in the REST API plugin! I should have RTFM: You need to supply a body of {"reset": true} to the DELETE of /lights/# or /sensors/#. It's not documented for /sensors, though. Just deleted and rejoined a Hue bulb without power cycling it nor resetting it with a Hue dimmer switch (see captured packets below).

I think we should make this the default behaviour, when the body is not present, and use {"reset": false} for the current behaviour. @manup would you agree?

Of course, we still need to delete the resources when the node is deleted from the GUI. I've been experimenting with GUI events in the STD OTAU plugin: now the table highlights the node you select on the map, so this should be doable.

glad to hear it: #1923

[ebaauw]

Make sure to delete any links from /resourelinks resources on delete, see ebaauw/homebridge-hue#669.
