The Danfoss Ally Cloud protocol is implemented as an ESL script (E.Danfoss_Cloud) using the unit E.Danfoss_Cloud.unit and the curl utility to communicate with the cloud. Subsequently, the data is parsed in the ESL script and stored in structured variables:

Danfoss cloud configuration and access rights to devices

• In the Danfoss Ally mobile application (https://www.danfoss.com/sk-sk/campaigns/dhs/smart-heating/danfoss-ally) it is possible to connect devices to a registered Danfoss account. Registration is done when installing the mobile application and is to a specific the account is identified by an e-mail address (e.g. ipesoft@ipesoft.sk).
  Note: currently, apparently only the owner (Home Owner) has and an administrator (Administrator) roles have the right to access devices via the "Danfoss Ally API" interface. Other users roles do not have this right.
• Subsequently, creating a user account (for the same e-mail address) at https://developer.danfoss.com is necessary.
• After logging in to the account, it is necessary to create an application by clicking the Apps item (https://developer.danfoss.com/user/apps) and clicking the "Add app" button.
• The "Danfoss Ally API" interface must be added when creating the application,
• After creating the application, the situation is as follows:
  
• The items "Consumer Key" and "Consumer Secret" must be copied and the string Consumer Key:Consumer Secret must be created and converted to BASE64, e.g. using https://www.base64encode.org
  Example: if "Consumer Key" is M2i51jpJrgGpKr4TfwnI0XMLDD1nKMU9G and "Consumer Secret" is 1VT80QedtXJE3Xcu72LUjIvMwyvgVWziQ3NHEg, then the following string must be converted
  M2i51jpJrgGpKr4TfwnI0XMLDD1nKMU9G:1VT80QedtXJE3Xcu72LUjIvMwyvgVWziQ3NHEg and the BASE64 result is

• The result must be inserted into the structured variable SV.Danfoss_Credentials in the access_key column. So this structured variable will have as many rows as user accounts. We recommend entering the identification of individual user accounts (e.g. e-mails) in the account column.
• Subsequently, in the E.Danfoss_Cloud script, it is possible to set a different trigger for starting the reading than the Min object used:
  

  ONCHANGEMinGOTOTriggerChanged   ; this trigger can be replaced e.g. by a custom evaluated tag
  
  

• The test of writing (increasing the temperature setpoint for the first thermostat "Room Thermostat" / "Radiator Thermostat" devices by 0.1°C and then setting the original temperature) is in the E.Danfoss_TestWrite script.
