    Agree with your comments and look forward to working on getting the new system up and running.

    Anything new to report ? Sounds like we may be running out of time with Iris after that Iris is Shutdown that someone received the other day. That just sounds like they are getting the web content loaded up and ready to switch over at a moments notice. I wonder how much notice they will give us before shutting down. I would expect to get a month at least. But still need to download the software for the Pi 3+ once it's available and get everything setup. I have enough spare devices that I could get the new system running in parallel with Iris once SystronicsRF makes the software available.

    Something new is coming

    OK, if it's not real time is it NRT? What is the latency, which I know will vary with the users location but what is the latency for the AI itself. How long does it take to process the data and formulate the response and how will this performance be impacted when 1000 people are using it and it is being fed data from 50,000 devices. And does everything need to be NRT? Is it possible to classify responses with a priority ranking so that important responses are delivered ASAP and others may not be delivered for a couple minutes. Or maybe a user selectable filter on what messages they want. Or am I missing the while point and all this interaction is created by the user during which they would have the ability to define the priority or delay for a response. Can you give us a list of the keywords? That would help me figure out what I might want to the AI to say and how to phrase it.
  4. True, they are not going to invest any funds in developing the Iris platform further since they are looking to unload it after having deemed it not profitable. But if there is life after Lowes, it would be nice.
  5. Yes, that is a big gap that it would be nice if they did enable it. You could then poll devices for temperatures all around the house. It might be possible to create scenes in Alexa that react to temperature or motion or the status of a contact sensor.
  6. Below from th4e Alexa Developer site: ---snip--- We’re excited to announce that contact and motion sensors can now be connected to Alexa, and that updates from sensors can now activate Alexa Routines, unlocking new customer scenarios in home automation, monitoring, and control. Customers can connect contact and motion sensors to Alexa in two ways: either through a smart home skill that uses the new Contact and Motion Sensor APIs, or with a compatible Zigbee sensor paired directly to Echo Plus or a compatible smart home hub. And starting today, SmartThings customers can use the sensors connected to their SmartThings hub with Alexa by enabling the SmartThings skill. So now, with the appropriately configured smart home skill or connected Zigbee sensor, a customer can ask, "Alexa, is the master bedroom window open?" and Alexa will respond with its status. ---snip--- Full story here: https://developer.amazon.com/blogs/alexa/post/bda9d70c-2f0d-454d-9939-2eb82868cf35/announcing-contact-and-motion-sensor-apis-and-integration-into-alexa-routines-adding-new-home-automation-features-for-customers-and-new-opportunities-for-smart-home-developers

    Thank you that puts my mind at ease with respect to interference problems between ZigBee and Wi-Fi.

    I've since done a little more digging to understand what SystronicsRF was talking about and found that BT and 2.4GHz Wi-Fi do not use the same channels. Wi-Fi uses channels 1 thru 11 and ZigBee uses the next 16 channels above that so they do not overlap. So both operate in the same band but do not use the same channels or frequencies.

    Speaking of monitoring RF activity, will you have any provision in the software for users to see a map of their devices and how they are connected to hubs (controllers) as in what slave devices are providing relay functions for each end device(slaves), signal levels, channel used, etc. You mention that our current hubs have all three transceivers on board, but in that case they were designed to operate in close proximity to each other so any interference should have been taken into account. I don't know but they may be separated from each other physically on the board itself. When I look at a Raspberry Pi SBC, I notice that the BT and Wi-Fi chips/antennas are not immediately adjacent to each other as would be the condition when plugging three USB sticks into the Pi's USB ports which are clustered together. My concern was bringing three RF transceivers in close proximity to each other in a condition that they may not be adequately shielded or designed for. I realize these are milliwatt transmitters but still at less than an inch apart will their be any affects on the adjacent receivers? Are the digital signals used by the ZigBee and Z-Wave protocols subject to IMD or other types of adjacent channel interference? BT operates in the same band as ZigBee (2.4 to 2.483 GHz). I have a number of BT devices in my home such as speaker, soundbars for the TVs, and headphones to name just a few. How do ZigBee devices deal with this? Transmitting audio over BT is full time not intermittent packets of data, does this present a problem. "The system automatically chooses the quietest channels during the installation procedure" Will it also evaluate those links and change channels should performance/link quality degrade? Will it track channel usage of nearby systems/devices that are not part of the SystronicsRF network and adjust for their presence? "Z-Wave operates at 908MHz" Yes, as do many other devices. Z-Wave AFAIK is limited to two frequencies in the USA, 908.40 and 916.00 MHz, how many devices from competing systems can be tolerated on just two channels before performance is affected? Do you use time slotting to co-exist with systems/devices operating on the same frequency and reduce packet collisions? I know I have asked a lot here and most of it is generic meaning it concerns any HA system not just the SystronicsRF HA system. BTW, do you have a name for your HA system? Maybe you should buy Iris from Lowes, but hold out for a price drop, Lowes is known to mark stuff down significantly after 90 days. :-)

    Water leak Drop outs

    Vettester, last paired does not reflect the last time connectivity was lost/restored, at least not on my three 3315s. All were purchased and paired on 11/16/2017 and that is the date shown as "Last Paired" in the app. But two of them lose their connection with the hub almost EVERY DAY for a few hours then reconnect on their own. I have yet to figure out why. Only reasonable explanation is distance from the hub, but there are smart plugs between them and the hub that should be relaying their signal. I am thinking there may be some equipment that is running in the house that creates interference but I have not found a correlation to support that yet. The hub and leak detectors are stationary so the RF path should not be changing and both are no more than 30 feet from the hub with at least one device that acts as a ZigBee repeater between them and the hub. The third detector is only 8 feet from the hub and stays connected. I think I will try swapping them out one by one placing them in the position of LD #3 (next to the water heat in basement and less than 8 feet from the hub) and see if they stay connected. And also see how LD #3 behaves in the more remote locations of LD #1 (~22 ft.) and LD #2 (~28 ft.).

    I would like to see support for the Wyze cameras which have a SD card onboard for continuous or event recording which can be remotely accessed. Wyze also gives you free 14 day storage of any alarm event video footage, but those are limited to 15 second clips with what appears to be about a 2 or 3 second pre-trigger capture so you get to see what caused the alarm to trigger. They can alarm on either movement or sound. They also have time lapse recording if you have an SD card installed and you can manually enable recording of video and sound remotely from the app and use the two-way audio feature too. For $20 they are hard to beat. But they are meant to be used indoors. You can buy housings to cove them for outdoor use from third parties but I have no idea how well they will hold up as the case is not fully weatherproof, it has some openings where moisture in the form of humidity will get inside and no doubt damage components. Wyze says they are working on an outdoor battery model which may appear this year.
  13. Yes, I have our system set up the same. We both receive a NOTF on the phone but an audible on the keypads would be nice. I have all the doors that we normally don't use and those that are in the outbuildings all set to chime at any time of the day. That way if someone opens a garage door we know it in the house. This is helpful because not all the doors are visible from the house. I wish the tilt sensors could be included in the chime feature, for those I have a notification set. Also for the garage doors I use a rule under the Care section to notify me if either of the overhead garage doors is open for longer than 5 minutes. This is just insurance that the garage door has closed after you have left. Sometimes you hit the close button on the remote for the door and it closes, but if you don't hang around until it's fully closed you could have it pop back open because it encountered an obstruction or maybe just a little added resistance which can cause the door to reverse and open up. Or maybe the close command was not received. In any case the NOTF lets you know the door is still open and you can decide to check on it or not.

    My 2nd Gen Cameras now have audio

    Swap it out with one of your other cameras where audio is not needed.

    In my case and probably many others, with three network interface USB sticks in close proximity to each other plugged into the Pi have you experienced any problems with interference between them. The two ZigBee sticks will be on the same frequency but using different protocols correct? I realize the hub can limit its transmissions to one or the other but with 60 or more devices in the field, some 1G and others 2G, there could be instances of packet collisions/interference between them requiring retries/resending information which will just slow the network down. Or does having two ZigBee sticks allow them to operate on different frequencies and not interfere directly. But still there would be little separation between them in frequency or physical separation given how close the four USB ports are on the Pi board. If that is the case would it be of any benefit to use a short USB Type A M to FM extension cable to get some distance between the three transceivers. Also is using extension cables OK in instances where one may need to place the hub in a location that does not offer the best location for RF coverage. The hub could be placed out of the way and an USB extension cable run to a USB hub with one or more network adapters plugged into it at a location which gives better coverage, or separate cables used to get separation between the individual network adapters.
