CJ, can I get your 3D print files? I've been reading this thread on and off for a few months now and finally found the time to start my own replacement. This thread has been incredibly helpful. I would be happy to reimburse you for the time and materialsI've been reading this thread on and off for a few months now and finally found the time to start my own replacement. I would be happy to reimburse you for the time and materials. I can't even keep up with all of the stuff that I want to print for myself e.
I put my email address in an earlier post. If you want me to send stl files you should probably send me an email or perhaps someone knows a way to post my files to this site?
I think that the "echo dot intercom replacement" in each room will soon be "aware" of other "smart things" in that room, This should simplify the namespace for voice commands e. I've finally figured out what I want to do where the master station was, an ipad running some version of Domoticz though I've also been exploring Home Assistant and OpenHab.
I think that I'm just going to pick up some sort of wood molding at Home Depot this week to make a picture frame that will cover the old master, with a 3d printed grill to dissipate heat from the power supply and some sort of probably printed mount for the ipad.
I'm toying with the idea of also putting a separate power switch for each echo dot in a column off to one side of the ipad.
My OpenSCAD model is parametric, which means that I should be able to plug in the dimensions of a rough opening and produce a set of custom stl files without to much effort, though as often as not it produces something irrational. The code is still very much a work in progress. Too many hobbies, projects and chores If you want a set of custom files then you will need to populate a data structure for me which might mean exchanging multiple emails in an effort to properly document my data structure :.
My data structure "documentation" currently looks like this:. All the replacements look terrible. Just remove the old intercoms and patch the Sheetrock. You will be happy you did. You make an interesting point, but then again, I think that a gang of light switches also looks terrible.
Personally, I prefer the aesthetics of an Echo Dot in the wall over yet-another-wall-wart, and it was way easier than re-papering or painting a room. Perhaps it also comes down to the value that one places on home automation, though that value might not be antithetical to aesthetics.
For example, if I were building a new home today, I'd consider having no light switches in any of the rooms, but putting redundant sensors somewhere in every room, probably in the ceiling maybe hide some in light fixtures.
I think that we are only seeing the beginning of an explosive growth in inexpensive network connected sensors, and I see value in putting some of those devices e. Since I'm not building a new house anytime soon, leveraging the existing wiring and wall recesses in this 35 yr old home gave me an easy way to incorporate some of this new technology into my life.
Plus I enjoy mucking around with this sort of stuff :. NuSound Systems has a smart intercom replacement system with built in Google Assistant. This system truly updates your home unlike other retrofit systems, plus, you can get rid of that ugly main panel box in your kitchen. This new intercom system also interfaces well with other products like Nest Hello doorbells, lights, etc. Visit www. Just an eye sore. Patch the Sheetrock up, you will be happy you did. Not to mention that the NuSound Systems smart intercom replacement is cheaper than patching and painting every room I'm trying this project using Echo Dot 3s as the replacement.
My question is about wiring the room stations. Mine was a 6-wire system and There are 8 rooms, 2 doors, and a patio. I plan to get the transformer mentioned above that will output 12V and don't need to convert it to 5V. I bought some pigtail 4x1. Assuming i use the NuTone black wire as positive and black-white as negative, and connect the appropriate pigtail wires, how do I get power to more than one unit? Current only flows through the pigtail when it is plugged into the Echo, right?
So all the echos would need to be plugged in for current to flow? How can I wire this so that any of the echos could be unplugged and the other still work? Do I just short positive and negative as well as it going through the pigtail plug?
What wire do I need for this? They're thinner than CAT5 or phone wires? That will give you an independent 12V supply at each terminal and each plug will be active at all stations, whether a device is plugged in or not. Now here's the part about the current - so the individual power supply that comes with each Dot is rated at 1. That has still only 2. So don't worry too much about those smaller wires as the current is not that great - but you can improve things by at least doubling up on the wires for each positive and negative -.
It makes more sense to use both Red i. Since the Power Supply comes with Dual Terminals for Positive and Negative it is easy to just group the like colours together on the appropriate terminal. At each station, it then has the 4mm x 1. I soldered mine with heatshrink over but you can also use small wire nuts if you don' have that capability. Award Winning Design. On the cover plate Craig, the supplier OCWoods Creations is doing a custom size slightly oversize at 6.
It's not loose with the 4. This image shows the 'std' covers for the Nest Temp Controllers which gives you good idea of what they look like but of course the Intercom Box cover will just have a single round hole. These pics show the 'prototype' with just a piece of fiberboard as the wall plate - I'll update with final pics once I receive the final acrylic covers. Genie also makes a Wall Mount for the Echo Show 5 so if you wanted to put one of those in any of the station locations, that is also an alternative - same principle, just have to have Craig at OCWoods Creations make the cut-out accordingly for that Genie mount.
First of all, you don't actually need a controller here - it's not like the old wired system as everything other than the power distribution is all wireless; so it can all actually be set up on your phone. However I think it is nice - and useful - to at least have a video monitor at that location, at least for me, where I can use as monitor especially for video doorbell and security cameras.
If you have an 8 or a 10 even, that is not going to be completely contained stable if you have 2 x 4 construction - even for the 8 that requires a 6" deep shelf so needs to be constructed to extend out beyond the wall to safely accommodate a stable platform. The whole box doesn't need to extend, just the base shelf of the box. I'm re-thinking that to maybe put an Amazon Fire 10" HD there - but with a 15" wide hole to cover a Tablet Wall mount is going to come up short at 12" wide - that means a patch may be required although I could also just make a picture-frame surround to complete to finished drywall.
Still determining that but may well go that way. I'll put a removable plywood panel in to fill the hole, while still allowing removal for access to the power supply, before mounting the Tablet to that.
As mentioned I got a bit oversize and the nice thing is that, if you feel like you need a little bigger still if your drywall edges are rough then just request whatever size you need.
Ken Scott Thank you for your reply. Perhaps I am confused about how the individual stations were originally wired, as I made an assumption that I did not confirm.
In my particular install it used an IMA "central amplifier". This is a box that just sits in a closet and has the electronics that lets the stations broadcast inside or to the doors. There is no fancy "master unit" with radio and CD and other music functions. I don't think that changes any answers, but just a background. But, I don't think there are as many sheaths as the total number of stations 7 indoor, 2 door, 1 patio.
I've only taken off three stations so far; two indoor and the patio. The patio and one of the indoors have what I would expect as far as just the IW6 wire running to it. The other indoor station has multiple 3? I don't remember sheaths of IW6 connected to it. Based on that, and this page from the IMA install guide;. From memory I want to say there was five IW6 wires out of the IMA, so I assumed a configuration of something like; one was for the three upstairs stations being daisy chained, one for the front door and 2 entry level stations daisy chained, one for the back door, one for the 2 lower level daisy chained, and one for the patio station.
I suppose I'll need to pay more attention in my install ensuring that each station is driven in parallel from the transformer, and if I find a station with more than one IW6 wire, replace that with a sort-of Y or T connection, allowing power to flow both to the Echo at that station as well as around it to whatever it was daisy chained to.
Frank Marsh - OK your diagram helped show the situation you have - my apologies for lack of understanding of the Nutone configuration. Everything still ends up in parallel - it's just that some of your parallel connections will take place at the stations instead of coming all the way back to a central distribution location. The net result for the most part is the same - however it does mean that each single 6-way wire leaving the power supply could potentially be supplying up to three devices at least per the diagram spec.
Then at any station where you find two 6-way wires, then again join then up - as well as to your 12V pigtail. If there is only one 6-way wire at any station, that one is likely just the end of the chain. Hopefully this diagram makes sense - I have just shown Reds and Blacks going between each station but you can add in the Orange pair as well. So the one leaving the power supply will have to supply three devices, but as I described above that should still be within the capability of the wiring - but you are minimizing any losses by using three coupled pairs.
Ken Scott Thanks, Ken. I got it. Make sure you disconnect EVERY station before you join the wires together and connect to your power supply. Incidentally I can recommend the Eufy Video Doorbell as part of your new system - I have the Battery powered Wireless one as in does not require any wiring to it at all - wireless in both power and signal and it is fantastic! I had tried a Ring and had so many issues with it it would not work with my Samsung phone AT ALL and the volume was completely inaudible.
I returned it and bought the Eufy which is a really, really nice device; the video quality of the Eufy is also higher resolution. It connects nicely to my Alexa Network as well as independently to the phones with its own Eufy App - and storage is in local device memory and free! No monthly fees. Ken Scott Sure, all the old units are disconnected and wires isolated. I hadn't decided what to do with the door stations yet. The old door chime is mechanical, not digital and on a separate transformer, so I know the thing about needing to upgrade that transformer to power the Ring.
The thing is, the internet here is ADSL and pretty slow--lucky to get kbps upload--so I'm not sure a video doorbell is really any use.
I think I had heard good things about the Eufy though, so good to get another recommendation. But the thing about the Eufy wireless doorbell is that there are effectively completely separate Wireless Signals between the Bell and the Homebase which comes with it - this is completely autonomous wireless, not part of a regular wifi network; and then from the Homebase to your local network with 'normal' wifi, just like your Amazon devices use; for the homebase connection, it can either utilize your home router Wifi connection or you can connect it directly via Ethernet Cable to your router.
The doorbell to homebase range is not huge however - my homebase sits in my entry about 20 ft from the doorbell. The homebase plugs into a regular household ac socket, so wherever you have one convenient. If your Wifi router won't access it, you can always use some powerline adapters, which will transmit your local network over your household electrical wiring. Note that in order to connect the Homebase via Wifi, it must first be connected by ethernet but you can do that in the same room as your router - after it is enabled, then disconnect and relocate your desired location.
Here is the actual Wireless Doorbell it is simply screwed onto the door surround - no wiring to it at all please excuse the old tatty Intercom system doorbell - that needs to be removed and blanked off.
