Netatmo Binding

The Netatmo binding integrates the following Netatmo products:

  • Personal Weather Station. Reports temperature, humidity, air pressure, carbon dioxide concentration in the air, as well as the ambient noise level.
  • Thermostat. Reports ambient temperature, allow to check target temperature, consult and change furnace heating status.

See for details on their product.

Binding Configuration

The binding has no configuration options itself, all configuration is done at ‘Things’ level but before, you’ll have to grant openHab to access Netatmo API. Here is the procedure:

1. Application Creation

Create an application at

The variables you’ll need to get to setup the binding are:

  • <CLIENT_ID> Your client ID taken from your App at
  • <CLIENT_SECRET> A token provided along with the <CLIENT_ID>.
  • <USERNAME> The username you use to connect to the Netatmo API (usually your mail address).
  • <PASSWORD> The password attached to the above username.

2. Bridge and Things Configuration

Once you’ll get needed informations from the Netatmo API, you’ll be able to configure bridge and things.


Bridge netatmo:netatmoapi:home [ clientId="<CLIENT_ID>", clientSecret="<CLIENT_SECRET>", username = "<USERNAME>", password = "<PASSWORD>", readStation=true|false, readThermostat=true|false] {
    Thing NAMain    inside  [ equipmentId="aa:aa:aa:aa:aa:aa", [refreshInterval=60000] ]
    Thing NAModule1 outside  [ equipmentId="yy:yy:yy:yy:yy:yy", parentId="aa:aa:aa:aa:aa:aa" ]
    Thing NAPlug    plugtherm  [ equipmentId="bb:bb:bb:bb:bb:bb", [refreshInterval=60000] ]
    Thing NATherm1  thermostat [ equipmentId="xx:xx:xx:xx:xx:xx", parentId="bb:bb:bb:bb:bb:bb" ]

Configure Things

The IDs for the modules can be extracted from the developer documentation on the netatmo site. First login with your user. Then some examples of the documentation contain the real results of your weather station. Get the IDs of your devices (indoor, outdoor, rain gauge) here.

main_device is the ID of the “main device”, the indoor sensor. This is equal to the MAC address of the Netatmo.

The other modules you can recognize by “module_name” and then note the “_id” which you need later.

Another way to get the IDs is to calculate them:

You have to calculate the ID for the outside module as follows: (it cannot be read from the app)

  • if the first serial character is “h”: start with “02”
  • if the first serial character is “i”: start with “03”

append “:00:00:”,

split the rest into three parts of two characters and append with a colon as delimiter.

For example your serial number “h00bcdc” should end up as “02:00:00:00:bc:dc”.


If you don’t manually create things in the *.things file, the Netatmo Binding is able to discover automatically all depending modules and devices from Netatmo website.

Common problems

Missing Certificate Authority

This version of the binding has been modified to avoid the need to impoort StartCom certificate in the local JDK certificate store.
PKIX path building failed:
unable to find valid certification path to requested target

can be solved by installing the StartCom CA Certificate into the local JDK like this:

  • Download the certificate from or use wget
  • Then import it into the keystore (the password is “changeit”)
$JAVA_HOME/bin/keytool -import -keystore $JAVA_HOME/jre/lib/security/cacerts -alias StartCom-Root-CA -file ca.pem

If $JAVA_HOME is not set then run the command:

update-alternatives --list java

This should output something similar to:


Use everything before /jre/… to set the JAVA_HOME environment variable:

export JAVA_HOME=/usr/lib/jvm/java-8-oracle

After you set the environment variable, try:

ls -l $JAVA_HOME/jre/lib/security/cacerts

If it’s set correctly then you should see something similar to:

-rw-r--r-- 1 root root 101992 Nov 4 10:54 /usr/lib/jvm/java-8-oracle/jre/lib/security/cacerts

Now try and rerun the keytool command. If you didn’t get errors, you should be good to go source.

Alternative approach if above solution does not work:

sudo keytool -delete -alias StartCom-Root-CA -keystore $JAVA_HOME/jre/lib/security/cacerts -storepass changeit  

Download the certificate from to $JAVA_HOME/jre/lib/security/ and save it as (X.509 / PEM).

sudo $JAVA_HOME/bin/keytool -import -keystore $JAVA_HOME/jre/lib/security/cacerts -alias StartCom-Root-CA -file 

The password is “changeit”.
