# netatmo2mqtt
Get the measures from your NetAtmo thermostat and send it to your MQTT broker
# Why yet another tool around NetAtmo API
I tried many other open source tools on github but I did not find a perfect fit for me.
The main reason is security : most of the tools I reviewed are still asking for `client_id`, `client_secret` (perfectly normal) but also for your username / password and that's not acceptable for me. It's also forbidden by [NetAtmo guidelines](https://dev.netatmo.com/resources/technical/guides/developerguidelines).
The other reason is that the thermostat is synchronized [only every hour](https://dev.netatmo.com/resources/technical/guides/ratelimits) so simply using [getthermostatsdata](https://dev.netatmo.com/resources/technical/reference/thermostat/getthermostatsdata) was not enough for me (make a graph with a measure every hour is not very precise). So I finally used [getmeasure](https://dev.netatmo.com/resources/technical/reference/common/getmeasure) in addition to provide all the missing detail with a measure every 10 minutes (like on the website).
Update 2019-01-27 : I replaced `getthermostatsdata` (which is being [deprecated](https://dev.netatmo.com/resources/technical/reference/deprecated) by Netatmo) by `homesdata`.
So I build mine :(.
# Usage
## Prerequisite
You simply need Python3 (never tested with Python2.7) and the only dependencies are `requests` (to access the api) and `paho-mqtt` (for MQTT broker interaction) so this line should be enough :
```bash
pip3 install paho-mqtt requests
```
## Getting your refresh token
First you'll have to [create your app in the NetAtmo website](https://dev.netatmo.com/myaccount/createanapp) and then you can use curl on a server you trust to get your refresh token :
```bash
curl -d 'grant_type=password&client_id=&client_secret=&username=&password=&scope=read_thermostat' 'https://api.netatmo.net/oauth2/token'
```
Make sure to add a leading space to this command to avoid keeping this line in your shell history.
About the scope : for this program you only need to be allowed to read thermostat values, you can read the [API documentation](https://dev.netatmo.com/resources/technical/guides/authentication/clientcredentials) if you need anything else.
## Using the script
Easy, first try a dry-run command :
```bash
./netatmo2MQTT.py -c '' -a '' -r '' -n -v
```
and then a real command to add to your crontab :
```bash
./netatmo2MQTT.py -c '' -a '' -r ''
```
The secrets can also be set with environment variables, see the help for more detail.
## Help
```bash
seb@minus ~/src/netatmo2mqtt (git)-[master] # ./netatmo2MQTT.py --help
usage: netatmo2MQTT.py [-h] -a NACLIENTSECRET -c NACLIENTID -r NAREFRESHTOKEN -l LATESTREADINGURL -x LATESTREADINGREGEX [-m HOST] [-n] [-o PREVIOUSFILENAME] [-u UPDATEDREFRESHFILENAME] [-s TOPIC] [-t TOPIC]
[-T TOPIC] [-v]
Read current temperature and setpoint from NetAtmo API and send them to a MQTT broker.
options:
-h, --help show this help message and exit
-a NACLIENTSECRET, --client-secret NACLIENTSECRET
NetAtmo Client Secret / Can also be read from NETATMO_CLIENT_SECRET env var. (default: None)
-c NACLIENTID, --client-id NACLIENTID
NetAtmo Client ID / Can also be read from NETATMO_CLIENT_ID en var. (default: None)
-r NAREFRESHTOKEN, --refresh-token NAREFRESHTOKEN
NetAtmo Refresh Token / Can also be read from NETATMO_REFRESH_TOKEN en var. (default: None)
-l LATESTREADINGURL, --latest LATESTREADINGURL
Url with latest reading timestamp already stored. (default: None)
-x LATESTREADINGREGEX, --regex LATESTREADINGREGEX
Regular expression to get latest reading time from url. (default: None)
-m HOST, --mqtt-host HOST
Specify the MQTT host to connect to. (default: 127.0.0.1)
-n, --dry-run No data will be sent to the MQTT broker. (default: False)
-o PREVIOUSFILENAME, --last-time PREVIOUSFILENAME
The file where the last timestamp coming from NetAtmo API will be saved (default: /tmp/netatmo_last)
-u UPDATEDREFRESHFILENAME, --updated-refresh UPDATEDREFRESHFILENAME
The file where the last refresh token coming from NetAtmo API will be saved (default: /tmp/netatmo_last_refresh)
-s TOPIC, --topic-setpoint TOPIC
The MQTT topic on which to publish the message with the current setpoint temperature (if it was a success) (default: sensor/setpoint)
-t TOPIC, --topic TOPIC
The MQTT topic on which to publish the message (if it was a success). (default: sensor/mainroom)
-T TOPIC, --topic-error TOPIC
The MQTT topic on which to publish the message (if it wasn't a success). (default: error/sensor/mainroom)
-v, --verbose Enable debug messages. (default: False)
```
## Other things to know
I personaly use cron to start this program so as I want to keep the latest timestamp received from the API, I store it by default in `/tmp/netatmo_last` (you can change it through a command line parameter. You can also initialize it with an URL (check the argument `-l`).
## Docker
I added a sample Dockerfile, I personaly use it with a `docker-compose.yml` like this one :
```yml
version: '3'
services:
netatmo2mqtt:
build: https://github.com/seblucas/netatmo2mqtt.git
image: netatmo-python3-cron:latest
restart: always
environment:
NETATMO_CLIENT_SECRET: XXX
NETATMO_CLIENT_ID: XXX
NETATMO_REFRESH_TOKEN: XXX
CRON_STRINGS: "46 * * * * netatmo2MQTT.py -m mosquitto -t sensor/netatmo"
CRON_LOG_LEVEL: 8
```
# Limits
* This program only handles Thermostat for now (PR welcome for other sensors)
* Won't work if you have more than one thermostat (again PR welcome)
