Introduction: Connecting the SimpliSafe Video Doorbell to a Digital Chime

I recently purchased a SimpliSafe Video Doorbell and after installing it I found out that it caused my digital chime to constantly ring. After talking to SimpliSafe, and being told that the doorbell isn't designed to work with a digital chime, they sent me a Chime Connector to see if that would fix the problem. When I installed the Chime Connector the constant ringing stopped but now the chime wouldn't ring at all when the doorbell button was pressed. After talking to SimpliSafe again they told me that I had two options: 1) Replace the digital chime with a mechanical chime, or 2) Return the Video Doorbell and reinstall my original doorbell. I didn't want to replace the digital chime and believed that there had to be a solution to get the Video Doorbell to work with a digital chime. After a lot of Internet searching I found an Instructables posted by NaokiH5 titled "Adapting a Video Doorbell to a Digital Song Chime." NaokiH5 provided a nice wiring drawing but after reviewing it I realized I could eliminate one of the doorbell transformers in his design. Also, during my solution search I came across a lot of postings of people who were just looking for a material list and a wiring diagram they could follow to get their Video Doorbell to work with their digital chime. The following sections provide the Bill of Material and Wiring Diagram that I used to provide power to the SimpliSafe Video Doorbell so it will operate and to get the SimpliSafe Video Doorbell to ring my Heath Zenith digital chime when the doorbell button is pushed. While I only have a front doorbell I also included a Bill of Material and Wiring Diagram showing how I would install two Video Doorbells if I wanted to have a front and rear Video Doorbell.

I hope this helps you get your SimpliSafe Video Doorbell working with your digital chime.

Step 1: Bill of Material - Single SimpliSafe Video Doorbell

I used the following components in my front door, single Video Doorbell installation:

1 - SimpliSafe Video Doorbell

1 - SimpliSafe Chime Connector

1 - Heath Zenith Multi-Tune Chime

1- 120V/16V AC Door Chime Transformer

1 - URBEST HH52P AC 24V Coil DPDT 8 Pins Electromagnetic Power Relay w DYF08A Base

2 - Fairchild Semiconductor 1N4001 Diode, Standard, 1A, 50V, DO-41

18 Gauge Doorbell Wire

I purchased the Chime from Home Depot. I purchased the Relay and Diodes from Amazon. You can use chime, relay and diode components from a different manufacturer as long as their component meets the same specifications.

Step 2: Identify 'Coil' and 'Switch' Side of the Relay

The relay in my Bill of Material has two parts - the relay housing and the base - and may come as two individual items. To assemble, insert the housing into the base, the pin configuration on the bottom of the housing will only fit into the base in one way. Your relay may not look exactly like this but you should be able to identify the 'Coil' side and 'Switch' side using this picture as a reference.

Step 3: Wiring Diagram - Single Video Doorbell

Follow this wiring diagram to install a single Video Doorbell by connecting each wire to the corresponding components and terminals.

Wiring diagram notes:

  • Turn off power to the transformer at the breaker panel when wiring the components together.
  • Line colors used for clarity to show each individual wire run, doorbell wire typically has a red and white wire.
  • Install diodes with cathode end (represented by solid black line on the diode symbol and a similar marking on the actual diode) connected to each terminal as shown.

If you wanted a single Video Doorbell (i.e. for the front door) and a regular doorbell (i.e. for the back/rear door) then follow this wiring diagram for the Video Doorbell and just install the regular doorbell per your chime manufacturer's instructions using the same transformer as depicted in the wiring diagram.

If you don't feel comfortable performing this installation, an electrician can do this for you.

I've included a downloadable PDF if you prefer to have a printed copy to reference when doing the installation.

Step 4: Bill of Material - Two SimpliSafe Video Doorbells

If you wanted/needed to install two SimpliSafe Video Doorbells then your bill of material would look like this:

2 - SimpliSafe Video Doorbell

2 - SimpliSafe Chime Connector

1 - Heath Zenith Multi-Tune Chime

1- 120V/16V AC Door Chime Transformer

2 - URBEST HH52P AC 24V Coil DPDT 8 Pins Electromagnetic Power Relay w DYF08A Base

4 - Fairchild Semiconductor 1N4001 Diode, Standard, 1A, 50V, DO-41

18 Gauge Doorbell Wire

Step 5: Wiring Diagram - Two Video Doorbells

Follow this wiring diagram to install two Video Doorbells by connecting each wire to the corresponding components and terminals.

Wiring diagram notes:

  • Turn off power to the transformer at the breaker panel when wiring the components together.
  • Line colors used for clarity to show each individual wire run, doorbell wire typically has a red and white wire.
  • Install diodes with cathode end (represented by solid black line on the diode symbol and a similar marking on the actual diode) connected to each terminal as shown.

If you don't feel comfortable performing this installation, an electrician can do this for you.

I've included a downloadable PDF if you prefer to have a printed copy to reference when doing the installation.

Step 6: Relay Options

I used a Double-Pole Double-Throw (DPDT) 24VAC relay because I had it available and I knew the terminal configuration. You could use a Single-Pole Double-Throw (SPDT) 24VAC relay in place of the DPDT relay(s) in my wiring diagrams. Just make sure you know which terminals connect to the coil and which terminals connect to the normally closed and normally open switches.

There are lots of other relay options available that can be used in this design as long as you know which terminals connect to the normally closed switch and which connect to the a normally open switch.

    I bought my house new in 1996 and have a Nutone intercomm system as part of my doorbell setup. The house also came with a wired alarm system which worked well until the last few years when I started getting a lot of false alarms. I finally decided to ditch my old alarm system and went with a complete Simplisafe solution including the Simplisafe Doorbell Pro. It did not work because Nutone is a digital system and then I found your article. I am a retired IT guy so my knowledge of hardware at the circuit level is not that get good so I asked a friend of mine who is an electrical engineer to help me out. Your solution worked exactly as documented. We did not run into any issues implementing your solution. I just want to thank you very much for posting this solution.

    I sure hope you still moniter this page and answer question. We are looking for the Double pole double throw relay that you used too. Could you tell me which one you actually used for this. Thank you for your help and I so truly hope this works cause I do not want a doorbell that just goes ding dong. I like mine.

    Question 8 months ago on Step 6

    I have installed the simplisafe doorbell using your configurations I have sent a picture please advise me if the connections are done correctly. I do not get any response from the doorbell although when crossing the wires at the transformer it appears that I have power. Also do I need a dioade at the doorbell in addition to the two at the relay?.

    Sorry for the delay in responding, your message got buried in my Inbox. You don't need a diode at the doorbell. Reviewing your picture it looks like your chime connector is set up differently than the one Simplisafe sent me. I've heard that they have created a new chime connector to try to resolve this issue but I don't have one of the new ones to work with. I'm guessing that you tried to just install the chime connector without the relay per Simplisafe's instructions and that didn't work since you are trying this configuration. Your wiring connections all look correct. The only thing I can think of is to make sure you have the input side of the chime connector connected to the transformer and the video doorbell and that the chime connector blue and white wires are connected to the correct relay terminals. One other thing to check is that your diodes are oriented correctly. They should have a band marking towards one end of the diode, looks like the band is white on your diodes, and need to be installed per my diagram. If they are installed 'backwards' they will block the flow of electricity.

    Hello all
    I can't seem to get my doorbell to communicate with the chime... both are powered, but ringing the bell doesn't activate the chime. The chime is digital...
    Transformer is 16V.
    Relay is same as specd in directions here.

    Double checked my wiring with your wiring diagram for single door bell and worked the first time. Now am enjoying the digital chimes! SimpliSafe still hasn’t felt the need to be compatible with electronic chimes vs their competitors. Thanks for the solution!

    Question 1 year ago on Step 1

    Hello, attached are my transformer (located on 1st floor) and chime located on 2nd floor. Would anyone be able to explain where the chime connector and the relay need to be placed?

    Looking at your pictures, I recommend that you put both the relay and the chime connector where the transformer is located; you don't really have enough room where the chime is located to install them and be able to put them out of site. However, since your transformer is on the 1st floor and your chime is on the 2nd floor you will need to run additional wires between the 1st and 2nd floor to be able to make the connections shown in the diagram.

    Question 1 year ago

    I installed the relay fix for my simplisafe doorbell and it worked with my electronic chime only for one ding dong then it would not ding much less ding dong after the first time. Can anyone help me fix this issue I have tested for voltage but it doesn't pull the relay in.

    What is the voltage rating of the low side of your transformer? 16V? Do you know how much current you are getting at the coil side of the relay? One other question, do you know which version of the Chime Connector you are using? SS came out with a Beta version that was supposed to fix the digital chime issue (it didn't seem to work) and if you recently got the Chime Connector they could have sent you the Beta. I haven't tested this configuration against the Beta version.

    How can I tell if I have the beta chime connector? I followed the diagram and all I get is a red light and a buzzing noise from the relay when I ring the doorbell? What did I do wrong?

    Remove the relay fix and connect your doorbell using the SS instructions if your doorbell doesn't do anything then more than likely you have a beta and it is now toast.

    Yes the low voltage is 16v, The digital chime worked 1 time since I started testing voltage after I tried the doorbell the second time and it didn't work there wasn't any. It shorted out the chime connector so apparently I received the beta chime connector. I contacted SS and they sent me another chime connector and now my mechanical door bell does work again. I removed the relay and all related wires and diodes and installed as stated in SS instructions. When I was speaking to tech support they questioned whether or not I was using a digital chime and told me that there doorbell is not compatible with a digital chime at this time.

    Thanks for posting this - I followed the instructions and it seems to be working. I did add a 25 Ohm resistor inbetween the chime connector and the relay to reduce the current (I measured ~2A when the doorbell button is pressed without it).

    Everything works fine as long as you give the doorbell a "decent" press: if you press and release it very quickly the relay jitters a bit and the chime does not ring. I'm not sure if this could be resolved with a different relay - any thoughts?
