Does this use z-wave, zigbee, or thread/matter? I would like to integrate with Home Assistant.

Answer This Question

Hello. No, no, and no. It only connects via Wi-Fi to the Ring app and interconnects to other Kidde alarms through a 3 wire circuit.

      Hi, I already have 5 of Model 30CUAR-V installed. If I buy one of these, can I simply disconnect one of the interconnected alarms and plug and mount this one in? If any of the interconnected alarms go off will Ring alarm system detect it?

        I have a 2400 square-foot open space. I need a smoke and carbon monoxide detector preferably battery operated that will send a alert to my phone. If I’m not in the building, My Wi-Fi is 5G. Please advise.

        Hello. This alarm is residentially rated and has to be hardwired. We do not have a smart battery-only smoke and carbon monoxide alarms.

          If I have other kiddee interconnect smoke and do detectors (from Before this new collaboration) and buy one of these will it send an alert to my ring app if any of them go off? Not just the new one of these?

          Answer This Question

          Hello. If another Kidde hardwired alarm goes off and sets off this alarm, the Ring app will let you know that the system is going off but not which alarm is going off.

              Can this detect natural gas leak?
              ByNov 24, 2025
              1 Answer | 
              Answer This Question

              Hello. No, this alarm detects smoke and detects carbon monoxide created when you burn fuel such as natural gas or charcoal but it does not burn hot enough to burn off the carbon monoxide. It does not pick up raw natural gas.

                The installation was very easy. For my house, I purchased 2 smart Kidde detectors (P/N RGCUAR-RW) from HomeDepot to receive notifications via Ring (2 for redundance should one lose wifi or stop working) and 4 non-smart Kidde detectors (P/N 30CUAR). I can now receive notifications from the non-smart detectors for my entire house since they are interconnected through the 3rd wire and save money by not having to purchase all 6 with the smart feature. Very happy with Kidde so far!

                Straightforward Install, Solid Build, Does the Job
                [This review was collected as part of a promotion.] This Kidde smoke/CO detector is exactly what it should be: simple, functional, and not annoying. The mounting plate lines up cleanly, the wiring harness is idiot-proof, and the whole thing snaps together without any drama. The unit feels sturdy, not cheap. Setup with the app is uneventful, which is what you want from a safety device. No unnecessary fluff, no gimmicks. It’s a clean upgrade if you want a modern detector that just works and doesn’t waste your time.

                We appreciate you choosing us! Your review showcases our commitment to prioritize quality and customer satisfaction. 
                  The ease of using these to replace my old Kidde hardwired units made it much quicker. Then installing them into my ring app so that I can see in realtime where an alert is coming from is a major convenience. Now when we have a false alarm, I can go to the exact place needed. A real game changer!

                  Absolutely Amazing Life Saving Detector. Product was put to the test on 10/10/2025 when a house fire started while we were not home. The ring notifications instantly told us of smoke in the house. This quick notification allowed for us to call 911 which prevented a whole house loss. The fire department assured us these saved our home and our dog. Even when they started to melt they still continued to alert.

                  Great interconnected system
                  Very happy with this purchase. First, it easily connects with my Ring app and comes with a Free indoor camera. Second, the installation was easy for a person with DIY experience, and I needed to change the old wire with the new one. (You need to know which wire is hot and neutral.) Third, it sends notifications to my phone if there is an Alert! This was my primary reason for buying this equipment. Fourth, this kiddie detector comes with an interconnectable feature that will activate all detectors if one is activated.

                    We had to replace all our smoke detectors due to the age of the house. We choose these since they are both smoke and CO2, can be monitored in ring app and were very easy to install.

                    Disappointed with mounting angle
                    Unit was easy to install and worked very well with Ring App in terms of setup. However, disatisfied with the aesthetic orientation of the unit. Followed the instructions making sure the "A line" on the mounting plate was parallel to the wall but unit when installed on plate is at a 45 degree angle to the wall. The ceiling junction box used throughout my home did not allow the use of any other mounting holes.

                        Great solution if you already have a house full of interconnected alarms. Connected it to our 12+ alarms and it sync'd right up. Does use a newer connector than the old ones, but there is a conversion jumper available.
