Getting Started with the Adax API

The Adax API provides a standard http-based interface for control of Adax thermostats. Software developers will be able to query status and send commands to their thermostat(s). Adax aims to follow the general rules of API compatibility and will protect implementations from breaking when bug fixes and new features are implemented. The API also strives to be self-documenting, easy to understand and use.

4.1. Remote Client API User Guide


Adax API is provided as a REST service and that allows you to:

  • Get your rooms target and current temperatures,
  • Change your rooms heating target temperatures.

Getting Started

For using Adax API you will need an authentication token for secure access and some REST services usage knowledge. The API is provided at the https://
api-1.adax.no/client-api/ address. The services description can be accessed at the https://api-1.adax.no/client-api/openapi in an OpenAPI format. You
could also use the provided Python and Java samples as a starting point.

Obtaining Authentication Credentials Required for Adax API

Using the Adax WiFi application you can create and get the authentication token used for accessing the Adax API. You should use at least the Adax WiFi
app version 3.7. The authentication token can be accessed following those steps:

  1. Navigate to Account Tab,
  2. Select “Remote user client API”
  3. Select “Add Credential”
  4. Give some name to the created credential and copy the generated password.

Using Adax API

The API provides 3 end points:

  1. /auth/ for authentication to the REST service.
  2. /rest/v1/control/ for controlling your rooms
  3. /rest/v1/content/ for getting rooms statuses. (add ?withEnergy=1 to get heaters power consumption for past hour)
  4. /rest/v1/energy_log/{roomId} – returns hourly energy log from current time back to 1 week for the specified room in 1h intervals.

Control and status endpoins accepts and returns json documents.

Local API User Guide


Local API allows controlling Adax WiFi generation 2 heaters ( thermostat that have both WiFi and Bluetooth) directly over local network. Local API
provides the following functions:

  • Connect heater to local WiFi network using Bluetooth Low Energy command.
  • Get heater status that reports measured ambient temperature, and target temperature.
  • Change target temperature.

Supported Devices

1. Adax WiFi gen. 2 thermostat (that have both WiFi and Bluetooth) with firmware version


Heaters listen on HTTPS (443 SSL port) and accepts REST API interface.


Each REST API call is authorised by passing Authorisation header with value “Basic ” + heater token. Token is assigned during heater registration.
Heaters use self-signed, self-generated SSL certificates.


No. Command HTTP GET Request HTTP POST Request Header Heater Response
1. Get Status /api/?command=stat&time=<<current_unix_time>> Authorization: 'Basic ' + <<heater token >> { 'targTemp': <<target>>, 'currTemp':<<current>> }
2. Change Temperature /api/?command=set_target&time=<<current_unix_time>>&value<<target _temperature>> Authorization: 'Basic ' + <<heater token >> HTTP 200

Registration Procedure

Heater is registered on local network using a Bluetooth Low Energy communication. During the registration, device is provided with WiFi SSID, PSK, and secured heater token.


  1. Heaters OK button is held until blue led starts blinking to initiated registration procedure.
  2. Generate/choose some random “Heater token” string value.
  3. Build heater registration command string “command=join&ssid=<<ssid>>&psk=<<psk>>&token=<<heater token>>
  4. Encode registration command as byte array (use ascii encoding)
  5. Scan for Bluetooth Low Energy device that advertises “3885cc10-7c18-4ad4-a48d-bf11abf7cb92” service.
  6. Get manufacturer data from Advertisement packet
  7. Check if manufacturer data byte 0 is equal to 5 (Heater device Type)
  8. Check if manufacturer data byte 1 two first bits are 0 (registered and managed flags are false)
  9. Check if manufacturer data bytes from 2 to 10 are not 0 (device_id > 0)
  10. If manufacturer data contains required values
  11. Connect to Device using Bluetooth Low Energy
  12. Register for “0000cc11-0000-1000-8000-00805f9b34fb” characteristics notifications.
  13. Split registration command bytes into multiple 17 byte chunks.
  14. Write each chunk to “0000cc11-0000-1000-8000-00805f9b34fb” characteristic ,with 1 byte header where 1 marks last chunk, 0 marks all other chunks.
  15. Wait for notification on “0000cc11-0000-1000-8000-00805f9b34fb” characteristic
  16. Get Byte array from notification.
  17. Check if notification data byte 0 contains 0 value (registration successful), or 1 value (WiFi connection failed)
  18. Get device ip address from notification data: bytes 1 to 4.
