+### Call home client
+
+The call home client sends health or error data from your deployment(s) back to Redis. You can disable it by adding the following to your REC specification:
+
+```yaml
+spec:
+  usageMeter:
+    callHomeClient:
+      disabled: true
+```
+
+{{<note>}}
+The REST API approach used for Redis Software deployments will have no effect on Kubernetes deployments. You must use the REC specification method shown above.

 The call home client collects data hourly and sends daily usage statistics to Redis with a POST request to `https://usage.redis.io/callHome`. Reports include memory usage, shard details, enabled features, and other operational metrics. To prevent increased load when multiple clusters are running, the daily report is sent at a random time.
 
 These reports provide insights into license consumption, which helps Redis to ensure performance metrics align with contractual agreements, optimize service delivery, and offer proactive customer support.

 We recommend contacting [Redis support](https://redis.io/support/) before making changes to call home behavior.
