====== SW releases ======

This section reports last SW release version and relevant release note for all available applications

  * Smart Hombrewing Application
  * Smart Thermostat Application
  * Smart BBQ

Notice that the FW is specific for your application, smartPID HW platform is generic but if you want to change the application type you need to contact smartpid@arzaman.com

this is the repository where you can download the last .bin (binary file) to be loaded on the SmartPID controller via USB interface
For details on upgrade procedure please refer to installation&config manuals or the specific section on the wiki

the **android smartphone app** is common to both applications and can be downloaded directly from [[https://play.google.com/store/apps/details?id=fred.com.smartpid&hl=it|google play store]]
