Rebuilding the Nest plugin

[leecollings]

Ah I see. In all fairness, I don't see the difference in the 'AWAY' and 'ECO' switches in the current Nest plugin. They are the same thing aren't they?

[Akerboom]

This is what I was looking for, didn't know it was added to Domoticz recently. Good going!
I'm only getting 4 devices for my Thermostat, none for my Protects. Should I allow more than 5 minutes for new devices?

Also are you planning to support the Camera?
I'd love:
- Webcam support using the snapshot_url and refreshing
- Motion/Person/Sound/Zone detection

Cheers!

Ah I see. In all fairness, I don't see the difference in the 'AWAY' and 'ECO' switches in the current Nest plugin. They are the same thing aren't they?

AWAY will set the eco temp, but resumes the scheduled temps.
ECO sets the eco temperature, until ECO is deactivated (Ignoring any schedules).

So, if I leave my home for 2 days.. with AWAY activated, then in the evening my heating turns on according to the schedule.
In that case I need to override all scheduled temps with the manual ECO button.

Also, unfortunately I had to remove this plugin due the the errors mentioned by Poudenes (above).

But it is working some time, first time ever i got a reading after a smoke alarm vent off. Never happened before the rebuilded plugin.

I'm currently testing it against Nests official simulator. This is a fake home with a thermostat, a camera and a protect. Maybe I'm testing the wrong way, but it all works fine here:

Please note that I do not own a Nest Thermostat any more, so I'm dependent on these tools to develop this domoticz plugin. Camera support is not planned.

To those who have errors, can you please describe what your Nest environment looks like (how many homes, thermostats, protects and such). Please be as elaborate as possible since I can't reproduce these errors myself right now. That makes it kinda difficult to figure out what's wrong. If I can get the plugin to break it will most likely be an easy fix but until then it's just guessing.

For what it's worth: when I had it running on a recent Debian install (9 I guess) I wasn't able to make connections to the outside world, causing all kinds of weird errors. Back then I did a reinstall of an older Debian and everything worked just fine. Most of the errors that I see consist of a lot of errors not getting data at all. I'm not a Linux/Debian wizard so I don't know what was going on (apart from it breaking like mad).

This can be seen in the log of @Clemen for example:

Code: Select all

It may just be that the NestOAuthAPI plugin is a little more verbose about what it's trying to do.

[dotms]

I did some additional work, restructuring and troubleshooting. I'll be uploading the changed code to my github shortly, and will be doing a test compile on a Linux machine tonight. Please help me in testing this and pointing out if things break!

Things fixed

• Away mode in case of multiple homes/structures. Probably worked fine with a single home, but it could have caused the wrong home to be set to away.
• Manual eco mode implemented.
• Improved logging of API interaction.
• Quite a bit of small fixes.

In my case some of the things that did not work (like setting away) were caused by incorrect permission settings. As far as I can see the following permissions in the Nest developer portal are needed for current or future full access. Some are currently required, some may or may not be used in the future. I think it's best to enable them anyway, so you don't have to change them at a later point after you find out things don't work and you don't know why.

- Thermostat: Thermostat read/write (currently required), Energy read (possible future use)
- Camera: Camera + Images read/write (possible future use)
- Smoke+CO Alarm: Smoke+CO Alarm read (currently required)
- Security: Security State read (possible future use)
- Other permissions: Away read/write (currently required), ETA read (possible future use), ETA write (possible future use), Structure read/write (currently required), Postal code read (possible future use)

[Akerboom]

Do we need to compile Domoticz from your brache for testing?

[dotms]

Yes. I don’t want to go through the trouble of putting in pull requests (and bothering gizmocuz) to the development domoticz repository while it’s still in feature testing (consider it alpha). It is synced up to the development branch though.

[Akerboom]

Not building for Arm 32bit (RaspberryPI) I suppose?

[dotms]

That's what I'm currently doing. On my Windows desktop build is done in like 1-2 minutes, on my Raspberry it's more like half a day.

[Akerboom]

happy to test if you can share the binary

[dotms]

Been doing some cross-compilation because compiling on a rpi is unbearably slow. Running into some compilation errors on Linux that I don't get when building on Windows, probably some non-portable code. Will look into it later. For now, compiling it via MS Visual Studio should work. Other platforms probably not.

edit: Can't get cross compilation to work for now. Ironed out some issues though. Should build on non-Windows now. Leaving the rpi to compile overnight.

edit 2: built successfully on a fresh Debian 9 amd64 install. I don't expect any problems Pi, but will not be putting time in testing on it since the thing is too painfully slow.

[tcviper]

Is working very well so far with Thermostats and Smoke/CO Protect. However, will Camera/Hello support come also anytime soon?

[dotms]

As mentioned earlier, camera support is not a priority for me right now for a number of reasons:

- I don't have a camera, never had one either
- I have no idea what its uses are and what useful information for these things would be
- My time is limited and I want the current plugin to be confirmed stable and integrated first before expanding it to new areas.

Never say never though

[Akerboom]

I'd like a switch in domoticz to activate when a 'person' is spotted in a specific 'zone' on my camera.
Then I can activate the light or broadcast the presence on my google home. In the nighttime I might want to sound the alarm.

When your code is in place, I'll be happy to have a look if I can create a PR to add camera support.

[poudenes]

Hi All,

Tried in Beta version v3.9631 to use Nest OAuth method but after less then 12 hours i got still get the errors in log.
Is there someone rebuild this plugin or must we forget this method to link nest thermostat en smoke detectors in Domoticz?

Nest throwing a 307 redirect either means:

• There is some maintenance happening at their side. That should be transient and resolve itself.
• You hit some rate limit. This can be fixed by polling less frequently.

The latter case which is something that needs to be changed in the plugin. Unfortunately for us Nest does not tell us the actual limits (except that you have crossed the limit) so it remains a guess what a good interval is.
