[wiz] Initial contribution

[ccutrer]

This binding integrates WiZ Connected smart devices.

This is a successor to the community marketplace version of this binding, most recently maintained by @frejos, bringing it up to date with openHAB guidelines and standards, to be part of the main distribution.

User visible changes:

• Renamed binding to just wiz, instead of wizlighting, since they offer non-lighting smart devices as well
• Renamed thing type, channel type, and channel ids to be lower-case-hyphen
• Removed wiz- prefix from thing type ids
• Removed dimming and state channels from color-bulb (use color channel)
• Removed state channel from tunable-bulb (use brightness channel)
• Removed state channel from dimmable-bulb (use brightness channel)
• Renamed fan-state channel to just state
• Renamed dimming channel to brightness
• Renamed light-mode channel to just mode
• Renamed bulbMacAddress and bulbIpAddress configuration parameters and properties to just macAddress and ipAddress
• Added temperature-abs channel
• Added fan speed, reverse, and mode channels
• Added fan-with-dimmable-bulb type, for a device that has a fan and a bulb; this is how new fan devices are detected. Fan-only devices cannot be reliably detected, so if that's what you have, you'll need to create it manually.
• Fixed INCREASE/DECREASE to speed channel changing temperature
• Fixed caching of fan state channel after a command
• Set color temperature to UNDEF when not in color temp mode
• Calculate the effective color when in color temp mode

Internal changes:

• Removed recreation of thing types based on binding version (openHAB core supports update instructions to handle this automatically)
• Use PercentType.ZERO, PercentType.HUNDRED, DecimalType.ZERO as appropriate
• Splits updates for fan and light apart, to reduce confusion
• Remove lots of debugging-style logging
• Changed lots of references from "bulb" to "device"
• Address several compilation warnings

@frejos: thoughts on renaming this to wizconnected as part of this, instead of wizlighting, since it supports smart plugs and fans, not just lights?

[lsiepel]

+1 for the renaming.

thoughts on renaming this to wizconnected

Or perhaps simply wiz? Disclaimer: just did a quick search, see for example https://faq.wizconnected.com/hc/en/3-wiz-legacy/faq/35-what-is-wiz-and-how-does-it-work/. And in HA also seems to be just WiZ.

[ccutrer]

@sfussenegger: what kind of fan do you have? I was browsing through the pywizlighting repo, and noticed their not-yet-merged-but-seemingly-abandoned PR seems to imply that a fan also has a light. If that's the case, we should put the fan-related channels into a separate fan# channel group. But if your device only has a fan, then as this PR currently is is reasonable.

[sfussenegger]

@ccutrer the model I have doesn't have a light, though the controller seems to be supporting it (including an unused connector). So the answer regarding my model is yes and no I guess. The WiZ app discovered it as a fan with light too, but it was possible to change the auto-discovered type to fan-only, suggesting both types are supported by WiZ and should probably be supported by the addon.

Great to see this is going into the core modules. Just let me know if you need any help with the fan stuff, I'm ready to help. My previous PR may contain some valuable information too.

[ccutrer]

@sfussenegger: I've updated the fan support significantly, but don't have a fan to test with. I'd appreciate if you could pull this down and try it out. Note that you'll have to re-create your things, and re-link your items. If you use discovery, it should detect it as a fan-with-dimmable-bulb, but you can still manually create a fan (only) thing. It would be good for you to try both (even though you don't have a light with it - I manually created a fan-with-dimmable-bulb against my light, and tested those channels). Also, I set the range of the fan's speed channel as 0-6, but perhaps it's supposed to be 1-6? It would also be nice if you could turn on DEBUG logging for org.openhab.binding.wiz.internal.utils.WizPacketConverter, and let me know the getModelConfig response. I suspect available fan speeds are in there, and then I can dynamically set the min/max based on the actual device.

@ccutrer I've tested today, and found that fanState is a boolean but the fan returns it as an int (0 or 1 I believe), leading to a gson exception. I've tried fixing it, but for some reason I can't get Eclipse to update the dependency. I'll have to look into this with a little more time.

Oh, interesting. I specifically changed to a boolean because I saw that StateRequestParam was using a boolean for state, and assumed the serialization must be auto-translating 0/1 to that. When I have some time (hopefully this evening) I'll see if I can find some attributes to control the serialization like that. If not, I'll revert it back to an integer.

[ccutrer]

@sfussenegger: I reverted the serialization to ints.

@ccutrer I can verify this works now. A few things I've noticed:

Channels

The new binding offers the following channels when installed via inbox as fan:

• Power (fanState)
• Fan Speed (fanSpeed)
• Reverse (fanReverse)
• Mode (fanMode)

Missing:

• Signal Strength
• Last Update

When installling as fan-with-dimmabel-bulb these channels are available. It's probably best to use the same channel-groups for <thing-type id="fan"> minus light.

I you want to follow the behavior of the Wiz app you probably want to suggest creating a fan-with-dimmable-bulb by default. Currently it's fan. My model doesn't have a light but it doesn't seem to know that with state and dimming available options. Therefore it probably should have been discovered with having a light.

fanMode

Value must be either 1 or 2, 0 is invalid:

11:38:15.515 [WARN ] [ternal.utils.WizResponseDeserializer] - Bulb returned an error on method "setPilot":  -32600, Invalid Request

Raw response:

echo '{"method":"setPilot","params":{"fanMode":0}}' | nc -u -w 1 192.168.0.167 38899
{"method":"setPilot","env":"pro","error":{"code":-32600,"message":"Invalid Request"}}

Anything higher > 2 is treated as 2. So while this is implemented as a switch in the Wiz app it look more like there could be more modes added, just like light modes. Not sure how you'd like to proceed there, but in my opinion using multi-values modes for fanMode just like mode would make sense.

Therefore adapt thing-types.xml to make <channel-type id="fan-mode"> look more like <channel-type id="light-mode"> with <option value="2">Breeze</option>

One more thing: I'm using the demo app in openhab-distro/launch/app to test after adding org.openhab.binding.wiz as a dependency. However, whenever I restart the app the binding doesn't load with previously created things show as NOT_YET_READY. It feels like I'm the one doing something wrong, not the binding. Or am I? Maybe you can tell me what I'm doing wrong. I am a Java developer and use Eclipse every day, but the OSGI stuff is new to me and just can't figure out what the issue is and it's driving me nuts. Thanks!

I'm not familiar with the demo app. I just use the OSGi console (using install -s <full file URI to JAR> for the initial install, and then update org.openhab.binding.wiz <full file URI to JAR> each time I recompile. And my things go offline momentarily, then immediately back online.

It should be noted that anytime I change the structure of the thing within this PR (adding, modifying, or removing channels), you'll have to delete and re-create it. Once the binding has been released as part of an official openHAB release, any further changes will require me to do "update instructions" that will automatically make changes to existing things to bring them up to date with the new structure. So don't expect the signal-strength channel to instantly show up on your fan-only thing!
