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

wborn · October 12, 2017, 8:07pm

I also hope you are not expecting the values to be in Fahrenheit, because all temperature values are currently Celsius only!

DSTM · October 12, 2017, 8:30pm

Celsius is fine.

Have just thought, should I be doing sendCommand rather than postUpdate?

wborn · October 12, 2017, 9:08pm

Yes you should use sendCommand for the binding to send a command to Nest. postUpdate will only update the value of an openHAB item.

It’s also possible to send commands via Paper UI by changing the values of your themostat using the “Control” page. This will also result in a sendCommand.

DSTM · October 13, 2017, 7:29am

Now i’m doing it right and sending a command and not an update, it’s working.

Apologies for being a numptie and thanks for your help in getting me sorted.

I have just noticed that errors appear in the log when changing the set_point. As it’s still in development I guess those are already known about, but if someone would like to see those errors just say.

wborn · October 13, 2017, 3:38pm

That’s great news! These posts will also be helpful to other people.

Can you post the warnings/errors that you see when updating the set_point? There shouldn’t be any.

DSTM · October 13, 2017, 3:51pm

sure.

@DSTM Maybe your browser is on a page generated by openHAB with an Image or Video item that has a URL that is null?

DSTM · October 14, 2017, 7:17am

Not as far as I’m aware. is that what the error is, then? I couldn’t see anything in it to identify what was triggering it.

If it’s nothing to do with the Nest binding, that’s good. Thanks again for your help.

wborn · October 14, 2017, 8:04am

@DSTM The error seems to be generated by a call made from one of the openHAB UIs (or maybe even an iOS/Android App). The call is processed by the Jetty server running inside openHAB and it then tries to proxy it to a destination that is null (hence the NullPointerException). So it looks unrelated to the Nest binding.

You could further debug the source of it by opening your browser debug view (F12). There is a “Network” tab where you can monitor all HTTP requests that are made. When a call fails it is highlighted in a red font. Typically it will have a 4xx or 5xx status code.

When you then click on the failed request it will show its details. E.g. the request URL/method and headers. Those details may help with finding the source of the error.

DSTM · October 14, 2017, 3:21pm

@wborn thanks. I think i’ve identified the problem.

dvd78 · October 17, 2017, 7:37am

Hi @DSTM i’m newbie on OA2 and i’m try to use the nest2 binding but i don’t understand how to install it. Until yesterday i was using the 1.0 nest binding with succes but i tried to use the one and i don’t understand how can i install the binding, for previous one i did it from paper UI but there i can only find the 1.0’s, is there a tutorial to install the new one?
i’m sure my Nest API ara running because with curl i can read messages from my thermostat.

Best
Davide

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.

dvd78 · October 17, 2017, 11:58am

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.
