Replicating Insteon Device Grouping in Home Assistant

After years of using Insteon devices, I migrated to HOOBS to integrate everything into HomeKit. This setup worked well, but I missed the advanced automation capabilities of Insteon. Now, I’m exploring Home Assistant to centralize my smart home setup and replicate the feature where controlling one device updates all related devices in real-time. This feature was crucial for maintaining consistent states across multiple keypads and switches. I’ve tried various methods in HA, like using automations and scripts, but the device states don’t update unless HA is restarted. I’m seeking advice on the best approach to achieve this functionality without resorting to polling, which could introduce unnecessary network noise. Any insights or solutions would be greatly appreciated!
