Constant struggle with VDB780B and W115C chime

I’m not sure yet about the W115 Chime issue, we’ll need to look into it further.

Is your IQ Panel 4 working well with Wi-Fi? If you’re having trouble with the W115, the VDB780B can work directly with the IQ Panel 4 as of firmware version 4.5.0. If you want to try it as an experiment, you could remove your VDB780B from the W115 and instead add it directly to your IQ Panel 4.

You would need to upgrade your IQ Panel 4 firmware to 4.4 first, and then to 4.5 or higher.

Once the IQ Panel 4 is on version 4.5+ you can add the VDB780B directly to the same Wi-Fi router/access point that the IQ Panel 4 is connected to. I can’t promise that will work better but t might be worth a shot.

Otherwise, we’re happy to keep troubleshooting the W115.
