ST and Professional Monitoring

And how often is the cloud unavailable? Historically at least once a month, usually more.

Thanks for the replies. Let me add some information to my original post. The existing contact and motion sensors are Zigbee-based. From what I’ve read, Konnected is geared towards integrating wired perimeter sensors, not wired smoke detectors. My ask here is if anyone is aware of a wired ‘smart’ smoke detector that will handle pass-through notification from the non-‘smart’ detectors.

The problem with ADT is that they will not allow me to bring my existing sensors on-board.

I’m not set on using the ST hub as the ‘security’ hub. My desire is a monitoring system that will integrate with the ST hub. This takes out the concern of ST cloud availability.

Low-cost is relative. With 26 windows, the ADT sensors alone would run me $650. Not including what I’ve already got sunk into the existing sensors that would be getting replaced.

Sorry, I missed that it was specifically smoke sensors. My bad.

Most security systems that do use zigbee use their own proprietary encoding over zigbee so their sensors don’t work with other systems. It’s just a typical industry practice.

And most monitoring services (Noon Light is an exception) are really picky about which devices you use because of reliability concerns.

Maybe someone else will know of something.

No worries on the miss and thanks for chiming in.

Safemonit seems to be the only solution I’ve found that will allow me to bring my existing sensors on-board as they appear to just leverage ST as the ‘security’ hub. But, that adds the issue of the ST cloud unavailability.

Actually, going back and reading more on Konnected, that does appear to be the solution for my smoke detectors. Looks like I’ll need a relay, but can tie them in to ST with the Konnected device.

And! I just noticed that the ADT sensors are on sale through BestBuy. $10 for contact and $20 for motion…just need to see if Lowe’s will take the Iris sensors back without the boxes. Unless someone else has a solution.

If not, you can always try selling the Iris sensors on here. There are always plenty of folks looking (myself included).

You don’t need Konnected to tie in your wired smoke alarm, you can use the appropriate Kidde / First Alert relay and connect it to any contact sensor with screw terminals (like the one from Linear), and just set it up with a device handler that makes it show up as smoke.

Looks like I’m bailing just in time.

Yeah, I actually thought that was why you were here. :sunglasses:

You have a bunch of options. First would be to use a Z-Wave or Zigbee sensor that has external contacts that you can wire in the relay from a smoke or CO alarm. I did just that here: Integrating Kidde Smoke / CO Sensors into SmartThings Properly . This would be good if you already have a bunch of wired sensors and they have a relay option board you can add.

Second option is the same relay but plugged into a Konnected board. There is a little setup but the Konnected product is a nice “packaged” solution to get wired stuff into the hub.

Third option is the same relay but plugged into a ESP8266 or ESP32 using ST_Anything (more DIY then Konnected but cheaper and more options of what to bring in): [RELEASE] ST_Anything - Arduino/ESP8266/ESP32

Last option would be just putting in a additional Z-Wave smoke sensor and connecting it directly. Like this one from FirstAlert is a combo Smoke/CO for $36: .

For monitoring you can use the “preferred” SmartThings Scout monitoring or NoonLight. Or switch to the ADT hub and sell your v2 hub if you can get everything at a decent price. I think yesterday the ADT hub was $100.

So cheapest/easiest I would think would be a extra Z-Wave smoke/CO, your existing sensors, and NoonLight but at least you have lots of options.

Last time I checked, scout doesn’t do any smoke detector monitoring, whether smartthings is in the picture or not. They only do “intrusion” monitoring. ( fire detection is very important to me because as a wheelchair user I need assistance to evacuate the house if I’m already in bed, so I always check the details)

Noon will notify you, but I don’t believe they are authorized to call the fire department. That’s a separate licensing process in most jurisdictions. I could be wrong on them, though, I haven’t ever looked really deep into their services.

ADT , in contrast, is Authorized to call the fire department in most jurisdictions, but they will only do so based on their own specific sensors. Not on anything else you hook up, no matter how you hook it up.

OK, I just checked: Scout will not dispatch for fire.

Noon Light will in jurisdictions that allow them to, but that varies a lot. They may be able to just call in like somebody walking by your house who hears an alarm going off. But it’s not the kind of authorized dispatch that ADT or Abode offer.

Thanks for the additional input. I did a good bit more digging last night and have a way-ahead.

  1. Lowe’s agreed to take back everything I’ve bought for a refund, including the items I no longer have boxes for.
  2. I cancelled the order for the v2 hub and placed another for the ADT version through Amazon with the $100 deal.
  3. BestBuy has the ADT/Smartthings branded sensors for cheap ($10 for contact, $20 for motion). They also have a deal on the “life” kit that includes one each smoke detector, CO, and flooding. $80 for the kit versus $100 buying individual. I picked up 15 contact (in addition to the two that come with the ADT kit), an extra motion, and two of the life monitoring kits.

Lowe’s also had the GE Z-Wave light switches on sale, so I went and bought them out last night.

I’ll worry about integrating my existing smoke detectors at a later date.


Matt from Noonlight here. First, thanks for kicking the tires on us. Appreciate the community wanting to clearly understand the pros/cons of what is in the market.

Just to clarify for everyone, Noonlight central monitoring centers are TMA 5-Diamond certified, UL listed, and fully compliant/licensed for monitoring for smoke, fire, co2, etc. We handle emergencies that require police, medical, and/or fire response across the country every day. And, of course, we handle our share of alarms that turn out to be accidental or false alarms as well. We never mind a false alarm though. It means you’re safe.

I won’t try to say we’re better than your options because I’m clearly biased :slightly_smiling_face:, but hopefully that clears up any confusion we created for you all on the dispatch front.


But If we are talking about the automated smartthings integration, you still depend on smartthings to notify you, which means Internet to the smartthings cloud to you, right? I understand someone could use their own phones to notify you manually, but I’m talking about something like a smoke sensor going off when no one was home. If the Internet was out, or the ST cloud was unavailable, there would be no notification to noonlight.

Yes, we do need to receive the signal (fire/ smoke detector or otherwise). So if your primary Internet was out and you didn’t have a backup cellular/LTE modem in the system, that signal wouldn’t get out.

ADT and others provide a service people value of course. No knock against them.

We think Noonlight offers unique benefits, but whatever monitoring option someone selects, they will need some level of working connection in order for a smoke or other signal to get out if that makes sense.


What JD is getting at is the fallacy in the cloud model being used. Moonlights notification is received via the Smartthings cloud service. So, if that cloud service is unavailable, then Moonlight isn’t notified. Right?

Sorry, this is a minor point but it’s just a pet peeve of mine. Most people have carbon monoxide detectors in their home, which is abbreviated CO. Carbon dioxide, CO2, is also life threatening in high concentrations but is much less likely to accumulate in most residential settings than CO.

I try not to make a big deal about that when i see it, but you guys are a commercial entity that expects people to pay for your services.

So basically, I’m holding you to a higher standard. You should know what you’re talking about to engender trust in your current and potential new customers.

Not trying to be a d!ck about it, just offering some honest feedback as a potential customer.

The ADT/SmartThings Hub (and so far only that model) Has an optional cellular module that will communicate to the ADT monitoring center. It also has its own battery back up. So it can communicate in more situations than any of the other models.

(Adding a cellular module to the other smartthings model hubs will not cause notifications to go through because they have to touch the SmartThings cloud first, and that’s a closed channel. So you can work around the Internet going out, but not the SmartThings cloud being unavailable.)

I think noon light will be a popular choice With some people, and it’s certainly better than the standard “smart home manager” feature. I just want to make sure that people understand what’s different about the Dual logo model so they are making an informed choice. :sunglasses:

Fair point on CO2. Typing quickly and my mistake.

@heythisisnate might be able to give you more detail (or correct me) since he developed the integration to us but on the ST cloud question - yes, i believe it would need to be up.


Welp…after the better part of the day I got everything setup. 42 devices in total but I haven’t added the smoke, CO detectors, or flood sensors yet. I’m giving the contact sensors a bit to make sure none of them fall off anywhere (had one do so in the garage) before activating the ADT monitoring portion.

I do still need to get a new VLAN setup for the hub. Anyone happen to have a list of required sites and ports it needs to function?
