Hi Matt,
yesterday I scanned my windows network from my laptop ... all my comfort devices appear at the network, is it secure for my home system ?

That's a good question - let me explain what is going on.

UPNP uses a discovery mechanism by broadcasting to the local subnet on port 1900 over UDP. Devices respond to these broadcasts by advertising their capabilities and devices. This is how the vast majority of IoT devices make themselves available to other devices (you may have also seen other devices such as Sonos, WeMo, Philips Hue, etc).

These broadcasts and responses are limited the local network and won't route to any outside networks so as long as your home WiFi network is secure there is no issue.

Furthermore there are a couple of additional layers of security layered on top of UPNP.
  1. the alarm.config file allows you to define the comfort devices (inputs, outputs, flags, counters and responses) which are permitted to be exposed
  2. A pin is still required to unlock the alarm (i.e. it is possible to set the alarm without a pin, but it is necessary to use the pin to clear it - just as you do with the keypad)
We have an additional security feature on the roadmap which is analogous to WiFi easy setup - which will only enable discovery for a short period following a request on the Web GUI. Combined with a password protected GUI and the concept of pairing Comfort with external devices this should make it even more secure.

Thanks,

Matt

Related with new firmware : 

1. I just upgraded to 1.0.0a from 1.0.0 , it happen only few seconds , is it normal ?
2." All zone devices now have the capability to act as a contact sensor" ... please explain more regarding this

1. Yes, it should only take a few moments; if it is successful it will report the new version installed and the upgrade button should be greyed out. If upgrading from a 1.0.0 release (such as 1.0.0a or 1.0.0c) you may need to attempt it a couple of times if the upgrade file isn't downloaded quickly enough. This issue is fixed in 1.0.1a.

2. The device will appear as a motion detector in SmartThings (although the icon can be changed to reflect that of a door etc) but it now also has the capability of 'ContactSensor' so SmartApps which allow you to select devices with that capability can find them.

1.For the time being can you limit the number of devices exposed to SmartThings to less that ~ 125?

Matt

Hi Matt, 

How to limit the number of devices exposed from comfigurator side  ?

In the alarm.config only list the Inputs, Outputs, Flags and Counters that you need (and to a maximum of around 125). 

I am working on instructions for a workaround which will selectively discover devices in batches to overcome this limitation.

Thanks,

Matt

Total all output + zone + response + etc = max 125 ?

Broadly yes - responses aren't included as they are manually added rather than discovered. The total number is limited by the available memory to the discovery process in SmartThings which is 100,000 bytes. Devices which have shorter names use less memory and as a result it isn't exactly 125 devices.

If you have a lot more devices you would like to discover, a new version which is in development overcomes this limitation with 2 step discovery but is not backwardly compatible. This version will form the basis of the commercial UCM.

Thanks,

Matt

Hi Matt is it possible to add a secondry Smartthings hub to this setup to be used in a partioned system using the same R-PI source.

Yes, that should work fine. With each ST hub, run discovery and select only the devices necessary for that partition.

Let me know how you get on,

Thanks,

Matt

Hi,

Can you explain what has happened please. ST shouldn't delete responses you have added via the 'add response' button in the ComfortAlarm Bridge device.

Thanks,

Matt

which menu I find add response ? at ST ?  in initial scan ST not find "responses"
My problem now :

1. all my lamp are dimmer that use momentary switch ( short press for on/off, long press dimming function ) . I have about 30 group of lamps, consist of fibaro group and hytronik dimmer control ( http://www.hytronik.com/products/dali-trailing-edge-dimmer-hdd2200.html ).  For Hytronik ,in comfort control menu 1 should set pulse few seconds in order to make same response with manual switch.  So if there is no setting about pulse response, become unreliable using on/off  at ST Things, i should click on or off several time , some time success to make it "on" sometimes not....Amazon alexa become useless, isnt it ?
2. the status device at ST not same with the real status of the device/lamp , annoying right ?
3. i have motorized gate, any command at alexa using "open/close" instead of turn on/off ?

Hi Matt.
I appear to be having some difficulty in changing the published devices... - I noticed that I'm missing a couple of devices (Comfort counters) that I really want to have in ST...
I downloaded the alarm.config from UHAI.. I noticed that one of the counters I wanted wasn't in there in the first place, so I added it...Whilst there, - and bearing in mind what you've previously said about discovery limitations, I decided to remove a bunch of devices that I could do without (I'm currently at 123 devices discovered in ST by the Comfort Manager smartapp). I reckon I must have removed 20 or so flag devices from the config file.Saved it.. uploaded it (apparently sucessfully)... restarted the service..
In the ST app I'm attempting rediscovery... Automation>smartapps>Comfort Manager>Next
It goes into the discovery screen, it says "discovery started" it shows the already-existing 123 devices previously found, and sits there with a spinny-wheel indefinitely... It never discovers any new devices.. I have a big red remove button at the bottom, but I'm wondering if that will delete *all* the devices already discovered? - I don't really want to do that, as I've already spent a fair while re-naming them in ST, grouping them into rooms etc... - Is there a way I can *selectively* remove devices that have previously been discovered? - I guess 123 devices has hit the limitation which is why I presume it won't discover any more...
Also, according to the UHAI webpage, I'm running 1.0.1a - but it says no upgrade is available, however the releases thread states 1.0.1c is the latest...
Cheers.
Paul G.

Hi Paul
You can selectively delete devices by removing the instance of the device by clicking the cog on the device which will give you an option to delete it.

It should find the new devices so long as you have uploaded the alarm.config file and restarted the service. Since there are so many it may take a while (ST has a limit of something like 5 devices a minute - and it will have to discover all the devices, not just the new ones).

You have the latest version, 1.0.1a is the newest 1.0.1c is still in the oven behind 1.0.1b :)

Thanks,

Matt

You need to add responses by clicking the 'Add Response' button in the ComfortAlarm Bridge 'thing' in ST things list. This will create a new thing called 'ComfortAlarm Response', you need to click it and use the cog to set the response code for on and off and rename it. 

This should then be able to call the responses to solve (1).

2. Occasionally (usually due to a hub or Pi restart) the ST thing and comfort device can get out of sync - use the refresh button in the ComfortAlarm Bridge thing to resynchronise everything.

3. Unfortunately the Alexa / ST integration doesn't provide the flexibility to change the action words - we are stuck with On and Off. We are looking at a richer Alexa integration but it requires the development of an Alexa Skill (which increases the complexity) and requires a cloud service hosted by us to do it - which can be expensive :(. I'll let you know how we get on.

Thanks,
Matt

When you use Responses here, are the Responses executed using The Response Number in the CCLX file?
If so then be careful as the Response number can be changed by Comfigurator when you edit responses
eg the previous response is edited to increase the actions beyond 8 then the Response uses up the next response number, so the response number does not point to the correct Response

It is better to map to Counters which trigger Counter Responses in Comfort. This gets around the response renumbering problem. Thisis why in the new UCMs eg KNX2, CBUS2, modbus, Zwave etc, mapping to Responses is not supported, instead mapping to Flags, Counters and sensors are yused

I'm not sure I follow exactly where you mean...
I've deleted the devices in the ST app just as you described...
But when I go into:Automation>SmartApps>Comfort Manager>Next...There is a discovery screen, which says at the top "Discovery started" followed by 1 paragraph of blurb, followed by "Select Devices (123 found)" followed by a comma separated list of the 123 devices...
That list of 123 has not altered since it was built several weeks ago after the initial discovery... if I remain on that screen, there is a spinny wheel appearing every few seconds so it certainly looks like it's doing something...That list of 123 includes the devices that I have since deleted in the ST app...If i select any device in the list, the screen moves to the tickbox list where I can select the devices I want to publish to ST... I can't delete devices there - all I can do is tick or untick...
I think my problem is that once discovered by Comfort Manager, those devices seem not able to be "undiscovered"... and because there's already 123 of them, I guess it's hit the limit and won't ever find any more unless & until I can remove some from the list...
As I say, I have the option to delete the "entire" list of 123 and start discovery again, but that would lose quite a bit of effort I've already done customising all the names, & putting them in the right groups etc...
What I really need is a way to delete devices from that initial discovery list.. - I've already removed them from the alarm.config file, uploaded it & restarted the service...
IF I delete everything & start again, no doubt it will discover the set of devices that I actually want... - but I'd have to re-do all that customisation... :-(
Is it possible for you to amend the "tickbox list" screen, so as well as tick/untick to publish to ST, I can also delete?
TIA
Paul G.
