Before updating
Record the current firmware version and device model. Verify the official package and release notes, and take a current configuration backup. Do not update a production device before identifying the problem addressed and possible integration impact.
Maintenance window
Assess the field impact of temporary relay unavailability and notify users. Provide stable power and network connectivity. For remote work, arrange someone who can physically access the device if recovery is required.
Post-update tests
Check web-interface access, IP settings, digital inputs, all four relay outputs, and active MQTT/HTTP integrations. Test Ping Watchdog, scheduling, or external modules separately where used.
Rollback and records
Have the supported rollback package and procedure ready before the update. Record time, previous and new versions, test results, and observed changes. Send logs with any support request.
