Warning: new lan discovery feature in 2.3 (thread closed by ST)

[pmusselman (Patrick Musselman)]

@Aaron

The feedback about devices automatically re-adding during the next discovery is valuable. Keep in mind, the need to delete devices following each new discovery session trends higher for the community (i.e., yall are power users and add devices more frequently than standard users). No promises - but based on the feedback, we will also evaluate the options for device level and/or a broad opt-out of the LAN discovery feature.

My favor part the last line. Yeah maybe will allow you to have security over your own network. Until such time it is yours. Did anyone run by your GC before forcing users into this?

@Aaron

We are not logging information, etc from non-connected devices (e.g., song track information from non-connected Sonos devices). Once a device is removed we immediately stop logging data from that device.

And I guess we just have to take at ST’s word too!

@Aaron

The devices are discovered via SSDP - which is a standard protocol the devices are using to announce themselves on the network.

It’s a standard industry practice to give users an option whether they want to connect to discovered devices or not. You do not give that option. That’s what pisses people off.

[pmusselman (Patrick Musselman)]

I see it all the time with UPnP. I turn it off. Why because I am given an option. Thank you @geko.

All zigbee and zwave devices require the end user to enter a pairing mode. Discovery is one thing, but adding it automatically is the issue. Even with hue, pressing the hue hub button shouldn’t also add all my bulbs automatically. It should ask me which ones I want to add.

This “feature” should have never been released in its current state. Nothing else in St security model acts this way.

[pmusselman (Patrick Musselman)]

@Aaron Reading up on this

https://en.wikipedia.org/wiki/Simple_Service_Discovery_Protocol that is listed in Live Logging. ssdpDiscover. Reading the 2014 DDoS attack methods. I proclaim not to be an expert in any of this but from a stand point of someone who has some knowledge of IT this not a good feeling and I don’t want this on my network.

Great job pointing that out Patrick…I guess my hub is going on it’s own vlan now.

Most WiFi smart home devices use SSDP for auto-discovery, a.k.a. zero-conf. It’s not something you can disable because it’s built into device firmware.

[pmusselman (Patrick Musselman)]

That is probably correct. But you still have to put the router or device in discover mode, correct? So I can’t see a device that would be in discovery mode all the time as a secure device. Is that fair? Certainly, you can choose not to broadcast your router name correct?

Since 6:28 the protocol has been run 5 times in Live Logging! edit @ 6:52

@pmusselman

No, that’s not correct. SSDP devices are always ready to be discovered. There’s no button to push like with Zigbee or Z-Wave devices.

[pstuart (Patrick Stuart [@pstuart])]

Even the older smartapps for lan devices would discover first, present a list of devices found and then allow the user to create the devices. Please restore this fundamental opt in to adding devices.

Even the documentation follows this paradigm.

[pmusselman (Patrick Musselman)]

@geko Ok I believe I understand what you are saying. The z-wave reference helps! Thanks.

[JDRoberts]

Personally, I don’t have a problem with the discovery, I want the choice about whether or not to add it to my account. And I don’t want to have to go through and remove it from my account again.

Every interaction with the app is physically challenging for me. A longer device list is physically challenging for me. Having to remove devices is physically challenging for me. Having to scroll to the next page is physically challenging for me.

So I only want the devices on my device list that I chose to have at my device list. I don’t want all of my housemate’s stuff on there. And I don’t want to have to go through and delete them, either.

But the reasons why I want this choice don’t really matter. Other people have other reasons. Some people will want automatic inclusion of everything. But not everyone will.

I just want to be asked which devices I want to add to my account and not have to go through extra work to remove the ones that I don’t want.

[pmusselman (Patrick Musselman)]

So bottom line is everyone should have been given an option. I agree and support that.

[pmusselman (Patrick Musselman)]

On a lighter note. Can you tell I just ate dinner. Is it possible to broadcast into the SSDP a string of text from time to time? I might have a few messages for ST from time to time.

Hi, somebody knows what happen if I have my own Connect and my devices currently in ST, It will be deleted or they going to crash with the networkid?

I´m still in 2.2.5 version

[staticfade (Marc Connors)]

Well this new option has unleashed a world of work for me. This nifty feature has lost my connection with my 40 hue Lights and hub. I have to re-add the hue hub. Fun part is getting all my motion rules etc back in order. But the best part. Wait for it. My hue hub hasn’t been found yet. Also in the add things once you click on it you are out of luck getting out. Only option is Save. No cancel nothing. This feature doesn’t seem well thought out

You can read the developer docs on this here: http://docs.smartthings.com/en/latest/cloud-and-lan-connected-device-types-developers-guide/autodiscover-lan.html#impact-on-the-developer

[ule]

Thanks, I will need to make others connect to avoid Automatic LAN to be searching and installing his own code.

[ule]

Somebody think is it necessary to create an Automatic LAN Blocker ?. An app that create a dummy device to avoid the automatic searching and installing, like a black list.

Example : App : Automatic Lan Blocker Connect.

Will search by all sonos, wemo, etc… It will find and create a dummy device to avoid install from Automatic LAN.

In this way the sonos do not log all activities in speakers if you don’t want
