NetAtmo Home Coach Integration

[emme]

Hi
Since NetAtmo Home Coach seems to be the "so new product" that even NetAtmo is NOT supporting it it its online dashboard... it looks that even the NetAtmo connector in Domoticz Hardware does not support or include such device either

the only way to access datas is to subscribe the NetATMO Connect program (for free) and trigger some script to grab info and update several custom sensors.

WORKFLOW
As I understood NetAtmo Connect works whis way:
- You post you request using: UserID, Password, ClientId, ClientSecret, MethodRequest (scope)
- The site replies with an AuthorizationToken
- Use this Token to inquiry the DeviceID
- Get your data back

REQUIREMENTS:
- Subscribe NetAtmo Connect (http://dev.netatmo.com ) and create a new app and keep the Client_ID and Client_Secret.
- HomeCoach DeviceID (Mac Address)
- UserId, Password for NetAtmo connect
- Several Virtual Sensors:
HomeCoach returns all these info:

Code: Select all

AbsolutePressure: 1002.4
time_utc: 1480697811
health_idx: 0
Noise: 60
Temperature: 24.7
Humidity: 40
Pressure: 1028.4
pressure_trend: "up"
CO2: 433
date_max_temp: 1480688755
date_min_temp: 1480684710
min_temp: 15.4
max_temp: 25.3

so you can create all the sensors you need

I grab the code from Netatmo tutorial and then I adapt it to my needs...
it is not yet finish (the Domoticz Update portion is missing because I have an error in updating the device) but here it is... if someone wish to integrate and optimize...
I'm not a programmer, so please be kind with my code

Code: Select all

I personally have a problem on this line:

Code: Select all

dz_co2_post = requests.post(DZ_HOST , data=params)

that timesout and returns a "200" but I see no changes (I'm running from the laptop and of course the IP was different and my laptopIP in in the whitelist )
if anyone have and idea why it does not work

Hope this would help!
ciao
