We’ve been having a serious argument with a C4 PoE Chime on a UniFi network for about a week now… yes… one door bell… one week… try explaining that to a client. We’ve troubleshot it to the extent of our abilities in house and have also exhausted Control4’s technical support who cite UniFi as the issue. Although I agree with them on this occasion it’s always frustrating to get to the ‘not our problem’ solution and that insulting support ticket resolved email!
The problem is this:
Chime works fine for 90 minutes to 2 hours, after this the Chime stops giving any ‘dingdong’ audio feedback on the button press and no longer makes an intercom call to the T4 touchscreen we need to to call inside. A power cycle resolves the issue for another 90 minutes to 2 hours.
The setup:
1) UniFi UDM Pro in the rack connected by DAC to:
2) Unifi USW-24-PoE in the rack (EA-3, T4 and other C4 stuff connected here) connected by CAT6 to:
3) UniFi USW-Lite-8-PoE at the gate to the property (Chime connected here)
Troubleshooting:
- Checked that everything is latest sw/fw.
- Fixed misconfiguration with STP switch priorities
- Defaulted Chime, removed from project, reinstalled.
- Exchanged Chime for another brand new one to rule out hardware fault.
- Exchanged Lite switch for an older US-8-60W to rule out physical problem with switch…no difference.
- Temporally connected original Chime to the 24p switch in the rack which has enjoyed 100% uptime.
So, we are now confident that the problem is with the second switch. But we have no idea what aspect of the second switch and clearly Control4 don’t either.
Any ideas or words of wisdom from other dealers would be greatly appreciated!
