Steps to Check Current Voice Assistant Release Version​

  • Go to the CloudFormation service and select the serverlessrepo-ESP-RainMaker-3P-Integrations stack.
  • In the Stack Version option, look for Tags > Semantic Version.

Minimum RainMaker backend version required: 1.1.15

1.5.0 (07-Oct-2026)​

  • General Improvements (Alexa & GVA)
    • New Feature: App-to-app account linking without re-login. Users already signed in to the RainMaker phone app can now link their account with Alexa or Google Home without signing in again.
  • Alexa
    • New Feature: Blinds and curtains (esp.device.blinds-internal, esp.device.blinds-external) now support "Alexa, open/close/raise/lower the curtain". Open/Raise moves the position to the maximum value and Close/Lower moves it to the minimum value. Alexa also shows the device state as Open or Closed.

1.4.5 (24-Jul-2026)​

  • General Improvements (Alexa & GVA)
    • Bug fix: User-node add/remove events were not processed, so nodes added to or removed from a user were not synced to Alexa and GVA.
  • Google Voice Assistant (GVA)
    • Improvement: Contact sensors now appear in Google Home as read-only Open/Closed sensors instead of occupancy sensors.

1.4.4 (20-Jun-2026)​

  • Google Voice Assistant (GVA)
    • New Device Support: Air freshener (esp.device.air-freshener) is now supported and maps to the Google Home Air Freshener device type. It supports RGB colour, indicator brightness, refill level, and esp.param.sensor-state.
    • Bug fix: Sensor states without a fixed list of values (for example, filter life) are now reported as numeric percentages.
  • Other Changes
    • Upgraded the Lambda runtime from provided.al2 to provided.al2023 and Go to 1.26.4.

1.4.3 (09-Feb-2026)​

  • Alexa
    • Bug fix: AddOrUpdateReport now sends the full list of endpoints to Alexa instead of only the last device. This affects only multi-device and bridge nodes.
  • General Improvements (Alexa & GVA)
    • Improvement: Alexa/GVA notifications previously depended on push notifications being enabled for those events. This is now decoupled.

1.4.2 (21-Nov-2025)​

  • Google Voice Assistant (GVA)
    • Bug fix: Corrected the min/max bounds of the Correlated Color Temperature (CCT) parameter, so they now appear correctly in Google Home.

1.4.1 (12-Aug-2025)​

  • Alexa
    • Bug fixes
      • Fixed an issue where custom mode handling for thermostats was not functioning correctly.
      • Fixed an issue where scene added/removed events were not being reported.
  • Google Voice Assistant (GVA)
    • New Features
      • Added backend APIs for account linking management:
        • GET user/link/status - Retrieves the user's account linking status.
        • DELETE user/link - Unlinks the user's account.
    • Improvements
      • Improved multi-device query performance by using a single Get Nodes RainMaker API call instead of making individual calls for each device.
  • General Improvements (Alexa & GVA)
    • Added new parameter mapping esp.param.dim as an alias for esp.param.brightness.
    • Devices without any standard parameters are no longer reported to Alexa and GVA, preventing unusable devices from appearing.

1.3.2 (10-Jun-2025)​

  • Alexa
    • Works With Alexa compliance: Light off and AdjustBrightness Up -> set brightness to delta, instead of increasing brightness by delta.

1.3.1 (06-Jun-2025)​

  • Alexa
    • Works With Alexa compliance: Fixed the issue in fetching the state of devices on Alexa State Report dashboard.

1.3.0 (26-May-2025)​

  • Alexa
    • Light Device: Works With Alexa Compliance
      • SetBrightness to non-zero when OFF -> Turn ON
      • SetBrightness to 0 -> Turn OFF
      • AdjustBrightness up when OFF -> Turn ON
      • AdjustBrightness down when OFF -> Stay OFF
      • Turn on when light is OFF and brightness 0 -> Turn on with brightness set to 100
  • GVA
    • Fix: Improved multi-device query handling. Errors from individual devices no longer cause the entire multi-device query operation to fail.

1.2.1 (30-Apr-2025)​

1.1.29 (06-Jun-2024)​

  • New Device Support
    • GVA: The new device type esp.device.dimmer is now supported. This device type maps to the GVA Switch device type.
