THEORY

The Dresden controllers are great and work with a Phillips Hue bridge and are super compact. https://www.dresden-elektronik.com/product/fls-pp-lp-wireless-ballast.html

Why would you do this?

We have control of these via IP and Serial, was custom built for a project. Let us know if you still need a solution.

The driver is available for purchase on the website for dealers.

What Control4 version are you running? Are these six button keypads the old 2 wide 3 high version?

I wouldn't bother going to track down cheap controllers online. If you have and need to buy time before upgrading ok use it. But to start looking for controllers that are cheap to use this is pointless. Willing to bet Control4 gets rid of this in the next few releases.

1,2,3,4 (but you don't get advanced audio) you have to try 5 for yourself. I wouldn't even want to run slow navigator from an HC-300 even if it works it isn't a good user experience.

It doesn't do anything. What is there to be scared about? Worst case you would recover the controller if it failed badly. Best case it updates. Reality it does nothing and stays at 2.9.1

Which Gen HC-300 do you have?

The system will update regardless of the HC-300 not. I have done it as well as others. It won't even say update failed for the 300. It just doesn't update. If you are getting failed to update driver are you sure the error pertains to the HC-300. Also this isn't a 3rd party driver really. It's the generic controller driver with the search tag modified to ID a 300 via SDDP. Use the Generic driver if you want but you then need to ID via IP. I've had updates hang that had nothing to do with even having an HC-300 in the project. Sometimes it just didn't start director after and manually starting it lets everything else complete. Now you can update without and ID later or do it before. In your case you may have other issues and want to add the HC-300 after. Also be aware you likely aren't going to get support from C4, even if you use just the generic driver. If you need support you might have to remove in order to get your issue looked at. Again this isn't 3rd Party, just something you can try, but should know that you are likely not supported in any way.

What does getting no control mean? You said you are able to connect what does that mean? You have ID'd it? What are you trying to use? What have you connected? What HC-200 do you have the Gen1 or Gen2?

Are you sure you have the right part #? The C416AMP3B doesn't have global inputs.

Confirm you have the correct MAC address in the driver and not the old WiFi one.

If your TVs are properly setup with static IPs the traffic should traverse the switch and have nothing to do with the router. LG hasn't removed WOL, the setting on the new TVs states WOL over wireless, but enabling does both. It think you should talk to your dealer about some proper troubleshooting and see what has changed.
