# Some Experiences With Shelly Home Automation Devices ## Shelly Duo & Shelly Duo RGBW As device discovery didn't work so well inside my network with the native Shelly HA integration I quickly switched to the custom integration Shelly For HASS. But still device discovery was laggy, unstable and unpredictable. I needed some experiments get it fixed. * Most important: I should have switched the devices from multicast (mcast) to unicast (ip-adress:5683) from the start - like is recommended in the [documentation of the official integration](https://www.home-assistant.io/integrations/shelly/). * Maybe I wouldn't have needed the fiddeling with the mosquitto mqtt server to get mqtt running as protocoll. Which definitely helped also a lot. * Disadvantage of the Shelly4HASS integration is that you can only control the RGB part _or_ the White part of the Shelly Duo RGBW while in the official integration you can switch between those modes. And the Shelly4HASS dev team doesn't seem to put a high if any priority to that. You still may log into the webserver of your device switch between those modes. But that's actually not the idea of Home Assistant, is it?
