Openhab2 Nest binding - 2.2.0.SNAPSHOT An Updated 2.0 Binding that works!

DSTM · October 17, 2017, 7:58am

hi david

you need to be running OH 2.2, i think. There’s a file called org.openhab.binding.nest-2.2.0-SNAPSHOT.jar somewhere on github (I can’t find where at the moment) and the readme for it is here:-

github.com

openhab/openhab2-addons/blob/master/addons/binding/org.openhab.binding.nest/README.md

# Nest Binding

The Nest binding integrates devices by [Nest](https://nest.com) using the [Nest API](https://developers.nest.com/documentation/cloud/get-started) (REST).

Because the Nest API runs on Nest's servers a connection with the Internet is required for sending and receiving information.
The binding uses HTTPS to connect to the Nest API using ports 443 and 9553. Make sure outbound connections to these ports are not blocked by a firewall.

## Supported Things

The table below lists the Nest binding thing types:

| Things                                  | Description                                                                                                                                    | Thing Type     |
|-----------------------------------------|------------------------------------------------------------------------------------------------------------------------------------------------|----------------|
| Nest Account                            | An account for using the Nest REST API                                                                                                         | account        |
| Nest Cam (Indoor, IQ, Outdoor), Dropcam | A Nest Cam registered with your account                                                                                                        | camera         |
| Nest Protect                            | The smoke detector/Nest Protect for the account                                                                                                | smoke_detector |
| Structure                               | The Nest structure defines the house the account has setup on Nest. You will only have more than one structure if you have more than one house | structure      |
| Nest Thermostat (E)                     | A Thermostat to control the various aspects of the house's HVAC system                                                                         | thermostat     |

## Authorization

This file has been truncated. show original

If you can find the snapshot.jar you need to download it and put it in your addons folder, and then you should be able to add Nest things in PaperUI in the normal way.

thank you guys, this evening i will try the new (for me) binding

dvd78 · October 17, 2017, 10:01pm

@DSTM @sihui thank you, i had some problem because i was running with OA2.1 but now with 2.2 my nest binding is ok

mladams922 · October 21, 2017, 2:47am

Out of curiosity, is there any chance anyone is working on getting the binding to work with Fahrenheit? It would be particularly useful for those of us in the States to be able to chose a scale and the V1.x binding used both.

wborn · October 21, 2017, 8:50am

@mladams922 I’ve considered working on adding Fahrenheit support to the binding even though I live in a Celsius world. However I would rather wait for the forthcoming Eclipse SmartHome unit conversion feature to land before adding it. All the off world scientists will then probably also be able to use their Kelvin unit with the binding.

mladams922 · October 21, 2017, 12:10pm

Is there a way to work around this for the time being? Or should I just use the old binding untill this gets updated?

wborn · October 21, 2017, 4:36pm

@mladams922 I’ve spent a few minutes to make a custom Fahrenheit build of the 2.2.0-SNAPSHOT Nest binding.

You can use it by first uninstalling the standard Nest binding and adding this org.openhab.binding.nest-2.2.0-fahrenheit.jar to the openHAB /addons directory.

That should make using Fahrenheits with Thermostats more easy until real Fahrenheit support is added to the OH2 Nest binding!

The minimal changes are in this branch on GitHub:

mladams922 · October 21, 2017, 6:48pm

That’s very nice of you! Thanks for that, I was looking into creating my own temporary branch of the binding until the official one was released. I appreciate this and I will put it to use.

Thanks again!

stress_nero1 · October 22, 2017, 5:59pm

Thanks for the update seems to be working fine for me.

ZenAKguy · October 23, 2017, 3:10am

@rlkoshak I meant no disrespect in this post. I was in the middle of a snoopy style happy dance at finally overcoming an months long challenge. I am new to open source and hugely admire the entire open source community that is making all of this possible. The talent, energy and enthusiasm is a welcome change from my life in professional IT. I’ve read and learned from a number of posts from @watou that are first rate. I share your hope that this did not alienate a core member of this community.

stress_nero1 · October 23, 2017, 1:12pm

With this binding values show correctly and i can change the mode of the thermostat but not the setpoint values and after selecting the values i hit the check mark button all is done under paper ui control.

stress_nero1 · October 26, 2017, 3:13pm

Hello i am having a issue making changes to the temp, the log says cant set to 80 C when trying to do it in Fahrenheit.

wborn · October 26, 2017, 4:42pm

Did you also uninstall the standard binding and copy the Fahrenheit binding JAR to your addons directory? See my previous comment.

DSTM · October 28, 2017, 7:53am

is there any chance of adding a channel for the “true radiant” feature, please?

The wife doesn’t like the boiler waking her up at a random time via the early-on feature of true radiant, but I’d like to auto-enable it for the rest of the day if I can, which can’t be done in the app but could be by openhab if the binding had that channel.

wborn · October 28, 2017, 8:59am

It looks like it is currently not possible to change this setting using Nest REST API that is used by the binding. You could ofcourse ask if Nest wants to add it, e.g. at their support forums.

Another way could be to see what calls your browser makes using the non-public Nest API. E.g. change the setting at your Nest Home page and monitor the network traffic using the developer tools of your browser (F12). Then you can make the same HTTP requests with openHAB.

DSTM · October 28, 2017, 4:05pm

Thanks. I’ll look into those when I have a bit of time.

Justas · October 29, 2017, 4:11pm

Hi,

I have managed to connect Nest Thermostat, nice to see values, thank you!

Questions:

If you buy Nest Thermostat in Europe you get this two relay Heat Link, can you implement Boiler relay control / monitoring in this binding?
Is there a way to monitor main heating relay is on/off? Then we could connect Nest to anything in Openhab. Because now if it is in Heating mode, you can’t say if its heating or not. When you have 0.5 C difference it does show Time to target as 0.
In developers Authorization URL when I accept permissions there is a feature, for Nest Thermostat to know when you are at home, can this be implemented to show up in binding?

Some Warn messages appear, does those needs to be fixed? Log below:

Yes I removed the original one and rebooted , so i will try again when i get home.

wborn · October 31, 2017, 6:17pm

These properties are not in the current Nest REST API. Nest knows people like to use it and have put this request on their backlog.
