Can you confirm that you mean the Alexa or Smart Life application on your phone can be used to switch on and off? Note that there are two apps for Smart Life. One is obviously called Smart Life, the other is Tuya. I would recommend that you enable the skill for both and then run the device search again.
I can turn the light on/off using both the Alexa app and Smart Life. I checked the wifi as I have a dual band router. The 5G band is listed but not used for anything in my home. I will try installing the Tuya app and see what happens. Thanks for the info!
Using the Device icon, the echo in the bedroom and kitchen are both listed as well as the switch which Alexa instructions had me change to light. There isn't a change option for wifi or anything else. I did check to see what band is selected in my iphone settings and the 5G option is listed but not used for anything.
I downloaded the Tuya skill and enabled it no problem. It found the device and I can turn it on and off with both apps. The Tuya skill put another instance of my device in the list in the Alexa app. However- Alexa still can't find it.
I have a similar issue so I want to chime in on this. I have a smart plug from SmartLife and it's connected to a lamp, called 'Pink Lamp'.
I have two 2nd gen Dots, one in the kitchen and one in my daughter's bedroom. First, I added the skill SmartLife to my Alexa, no issues turning the plug on/off using SmartLife app or Alexa app. However, I could use voice command on my Dot in the kitchen but NOT in my daughters bedroom. That one just replied, can't find a device named 'Pink Lamp'. Both Dots are registered to the same account and both are using my 2.4 GHz WiFi.
Since I'm using Smartthings (but SmartLife is not compatible with ST), I decided to use IFTTT to trigger 'Pink Lamp'. So, I created a virtual switch in Smartthings, using a simple IFTTT applet that turns SmartLife 'Pink Lamp' on. Then I'm using Alexa to turn my ST virtual switch on/off. Now Alexa has no clue I'm using SmartLife (since some people on other forums blamed SmartLife and the plug) but the same problem remains! I can use voice command from the Dot in the kitchen but the one in my daughter's bedroom still can't find the device named 'Pink Lamp'. I've tried to de-register that specific Dot, same problem.
I am having a similar issue with Smart Life & Alexa. Here's the issue:
I use Teckin plugs and light bulbs.
All worked without an issue since installation.
After installing additional new bulbs and switches, everything still works fine in the Smart Life app (and two bulbs in the Tuya app). Alexa would no longer control the devices.
After reading the forum, I tried rebooting everything from WiFi to every device affected in the house (there are many).
As suggested, I opened the Alexa app and deleted the unresponsive plugs & bulbs, and tried discovery again. and again. and again.
Also as suggested, I uninstalled & reinstalled the Smart Life app and reset the devices (they are all working through the app just fine).
Thinking once it was deleted, Alexa must not be able to recognize the devices again (even with editing the names in the Smart Life app) so I bought 8 brand new replacements. They loaded in the app flawlessly. Alexa will not recognize them.
I HAVE BEEN A USER SINCE THE VERY BEGINNING, and I believe I have done my due diligence, and spent quite a bit of money trying to figure this out over the course of the last 2 weeks, much to the chagrin of my loving wife, who is developing a rather negative opinion about this "Smart Home Thing".
The only other goofy thing that occurs is that Alexa discovers other instances of existing devices (from other apps & manufacturers) on occasion, and I need to re-delete these so she doesn't get confused (I think this is a separate issue, but include it for clarity).
I was having the same issue with Alexa not discovering the device however it was available in the Alexa app. I set up a routine “Alexa turn off the living room light” and vice versatility for on and it’s wprking flawlessly now. I never saw a step in any of the set up instructions to set up a routine...
Very similar issue. I have a Gosund smart plug. Its instructions say to discover it in the Smartlife app, then enable the Smartlife skill in Alexa, then discover the new plug. Well, the Smartlife app recognizes the plug. And the Smartlife app IS enabled in Alexa. But when I tell Alexa I want to discover a new device, and it's a plug, Smartlife is not on the list of Brands it knows - so Alexa help tells me to select Other as the brand. I select Other and tell it to discover, and it tries and tries and times out without discovering anything. Frustrating! I can contol the plug via the Smartlife app on my phone, but I can't get Alexa to find it.
Experiencing the exact same issues - extremely frustrating. Using a Gosund smart socket - I've tried and successfully enabled and linked the device to both the Smart Life and Tuya apps, and can control it from both of them. I've also enabled both within the Alexa app - but my Alexa dot repeatedly fails to discover the smart receptacle.
Has who'e had this issue been anyone been able to properly troubleshoot it?
I had similar behavior trying many things with the apps and devices, still not discovering the plug. However, I tried creating a routine (when this happens -> voice -> action -> smart home) as nick13bat suggested above and suddenly it was working by voice to turn on and off by device name. Thanks nick13bat, assuming that was the trigger.
