Hello everyone,

I'm having an issue with my Ring Intercom and a Comelit Simplebus system, and I'm hoping someone has seen something similar before.

My installation consists of:

• Comelit IKALL 16-call entrance panel (shared condominium entrance)
• Comelit Simplebus system
• Comelit handset 5701/5714K
• A second call point for the entrance of my private villa

For almost two years, Ring Intercom worked perfectly. It was able to detect and notify calls coming from both:

1. The condominium entrance panel (IKALL 16)
2. The private villa entrance

Recently, the IKALL entrance panel failed and Comelit technicians replaced some components.

Since that intervention, Ring Intercom no longer works correctly with both call sources.

What happens is:

• If I perform Ring's automatic setup using the villa entrance call, Ring recognizes that call perfectly, but calls from the condominium entrance panel are no longer detected.
• If I perform the setup using the condominium entrance panel instead, then Ring detects those calls correctly, but calls from the villa entrance are no longer recognized.

In other words, Ring can learn and operate with only one of the two call sources at a time. The other one becomes silent from Ring's perspective.

The strange part is that this exact setup worked flawlessly for years before the Comelit repair. The issue appeared immediately after components were replaced on the IKALL panel.

Has anyone experienced a similar problem with Comelit Simplebus systems?

Could the replacement of a module or a change in programming have altered the call signal on the bus in a way that affects Ring's auto-learning process?

Any suggestions on what I should ask the Comelit technician to check when he returns in September would be greatly appreciated.

Thank you!

Federico
