Alexa won't discover new devices since Indigo 2021.1

[jay (support)]

The skill is now available in most English speaking regions. If you are still having issues, please post the details and make sure you've already worked through the troubleshooting section of the Alexa docs.

OK, rookie mistake, I disabled the reflector access in the server for some testing It's now working, yaaay!

I have the same problem. The skill installed OK and linked to my reflector, and when I ask Alexa to discover devices I get the entries below in the event log, but no devices are discovered.

Code: Select all

   Alexa                           Alexa discovery request received, assembling reply...
   Alexa                           ...'TV' - Type: RelayDevice - Subtype: Switch

And you've tried everything in the Troubleshooting section of the docs?

If so, what does the devices section of the Alexa app show?

Yes, tried everything on the list. The Alexa app shows none of the Indigo devices.

My reflector seems to be working OK; I can use it with the iOS app.

But does it show any devices? If so, remove them all then rerun discovery.

Deleted all my devices. Ran discovery again. All devices rediscovered but still no Indigo ones.

Repeat, but disable any other smart home skills you have.

Also, make a note of the exact time you ran discovery so I can attempt to locate the attempt in the amazon logs.

Same result. Ran discovery at 2340 UK time.

I found it (the log entries that is). I have a suspicion I know why. Unpublish all devices except the Z-Wave devices then run discovery again. Pretty sure this will work.

Assuming that works, add Thermostat and discover. Somewhat sure this will work.

Assuming that works, add TV. I suspect this will fail to be discovered by Alexa.

Let me know what you find.

Hi Jay

Removed all but Z-Wave devices then ran discovery. All were discovered.

Added thermostat - discovered.

Added TV - not discovered.

Exactly as you surmised.

Alexa takes a "throw out the baby with the bathwater" approach to device discovery. If it doesn't like one of the devices, it doesn't accept any from the discovery reply. It also doesn't return any exceptions/errors when it doesn't like a device so basically we have to guess.

The problem is that those other devices have nothing in their address property (device.address) which is what shows up in the Address column in the Device List. I believe they're all from the same plugin, so apparently that plugin doesn't assign an address. The Alexa plugin assumes that all devices have something in the device.address property, so it just passes whatever the value is to Alexa. In this case it passes an empty string. Apparently, Alexa doesn't like empty strings for that field.

I will correct this in the next release, but if you know the plugin author (you?) the fastest solution would be to have the plugin put something in the address field. Even "unknown" would work, it just needs to exist.

Thanks Jay. It’s berkinet’s Meta (Pseudo) Device plug-in but I don’t think he supports it any more. It’s no longer in the plug-in store.

All my own plugins assign device addresses, but looking down my device list I see a number of devices from other plugins with "- none -" as the address.

As a test I added some temporary code to berkinet's plugin:

Code: Select all

   def addressCheck(self):
      for dev in indigo.devices.iter("self"):
         if dev.address == "":
            dProps = dev.pluginProps
               dProps["address"] = "None"
               dev.replacePluginPropsOnServer(dProps)

The devices can now be added. Thanks Jay!
