[1.4] In WaterHeaterManagement Cluster, The Featuremap and ClusterRevision values are Failure instead of Success.

[Ashwinigrl]

Description

In the WaterHeaterManagement Cluster, When we read the FeatureMap and ClusterRevision attributes from the DUT returns a failure response instead of a success response with the expected values. The sample app(Energy-Management-app) needs to be updated to correct the FeatureMap and ClusterRevision attributes response.

Reproduction steps

1. Execute the below mentioned command to put DUT into a commissionable state :
   ./chip-energy-management-app

2. Once DUT reach the commissionable state sent below mentioned command on TH.
   ./chip-tool pairing onnetwork 1 20202021

Once after successful pairing provide the below commands:

1. TH reads FeatureMap value from the DUT.

./chip-tool waterheatermanagement read feature-map 1 1

Did you try against PR #36201?

[jamesharrow]

The issue is that you need to use --application water-heater to enable the Water Heater cluster to respond on EP1 on Linux (or compile this for an embedded target with water heater enabled).

@Ashwinigrl - please retest with the extra command line option.

Note that the PR #36201 will move the Water Heater to a different endpoint once merged.
