My application doesn’t discover the adapter (local).

Please make sure that your phone is connected to the same network as the Daikin Altherma LAN adapter. Additionally please limit the network equipment between the Daikin LAN adapter as this can disrupt the discovery.

The Daikin Altherma LAN adapter uses Bonjour/ZeroConf to discover the unit. In rare cases an Android smartphone cannot successfully discover the Daikin Altherma LAN adapter. Please make sure your smartphone has the latest OS updates installed and reboot your phone, check then again.

If the above solution doesn’t solve the problem, the Daikin Altherma LAN adapter IP address can be fixed programmed in the Daikin Online Control Heating application, so that control is possible. This solution, should only be used when discovery via bonjour is not working. Please follow the following steps:

  1. Open the menu and select “general settings” 
  2. Select “fixed list” under Discovery. 
  3. Enter the IP address of the Daikin Altherma LAN adapter ( can be found in the DHCP list of your router). 
  4. Enable the check box and select “v” on the top right corner 

The Application will search manually to the adapter with the configured IP address and control via the application is possible.

If even with programming a fixed discovery on the Daikin Online Control Heating application your Daikin LAN adapter cannot be found please ensure that your router and smartphone supports the use of websockets.

If the test fails please check with your smartphone/router manufacturer how websockets can be supported.
