Well, at least you know that it works over https and the json payload confirmed that you have enabled insecure local access.
I think you have to use https but since you enabled anonymous acces you don’t need to use an auth token. You won’t get any feedback in a browser, just a blank page or in some cases “the page can’t be reached” but if you have the MiOS app open you can see that the scene runs instantly when called from a browser with https. Quite impressive that the app is updating live!

that’s because they’re using websockets. that’s a bi-directional socket connection between clients and servers. So, servers can push update to the client without polling. Less memory, less CPU and better UX for apps. That’s a right approach, kudos to the team for that.

OK I have finally gotten a token from my Ezlo Plus, I had to remove the controller from my Vera account and add it back again.
I can successfully send commands to the Ezlo Plus with authentication to get the hub info and to list devices.
However when I try to send a command to turn on an appliance plug device I see this in Postman:
I have triple checked from the Api Tool that I have the correct device ID
So why isn’t it working and why am I seeing this error ?

If I try it using Curl instead I see the same thing:

I am also unable to send a command to run a scene.
Again I have checked in the Api Tool that I have the correct scene ID:
Yet this error is returned:

Have you tried https without the auth token?
A HTTPS hub info get command without authentication does appear to work yes.

However if I try the commands to run a scene or turn on a device using HTTPS and no authentication, I still get the same errors I listed above.
So your saying that when the authentication has been turned off as I did previously, you still need to use https:// in your command rather than http:// right ?
Correct, that’s the only thing working for me.
OK so do my commands look to be correct for running a scene and turning on a device ?
Thanks
Yes, I’m guessing you have token in the headers in postman, if so remove them and try again. Or try to run a scene in a browser. I have not tried with devices myself, only scenes.
If I remove the token / authentication from Postman and set it to No Auth
I see the same error when trying to run a scene.
Ok, browser? Reboot hub?
Yes, click advanced and continue to site.
After clicking Advanced and Continue, I then just get a blank white page and the scene isn’t run.
I’ve rebooted the Ezlo Plus hub and trying again in Postman I still get the same error.

Ok, I found your problem for scenes. The url should be scenes, not scene.

OK that works now in Postman with or without authentication !
Not my mistake however @Oleh said it was “scene” with no S
run scene:
https://127.0.0.1:17000/v1/method/hub/scene/run?sceneId=NNN + authentification headers
So does anyone have a working command example for turning a device on and off ?
Thanks
Try replacing the dots with “/“ like in the api documentation /v1/method/hub/item/value/set?_id=09234njnj234&value=cooling#1_2
This was the command I was trying to use.
https://192.168.0.11:17000/v1/method/hub.item.value.set?_id=5f4e5871120bab1069c13c49&value_bool=true
If I change it to this instead with “/”
https://192.168.0.11:17000/v1/method/hub/item/value.set?_id=5f4e5871120bab1069c13c49&value_bool=true
I get the same error:
Item not found.
Yet looking in the online API Tool that is the correct ID for that device.
Using value_int=1 on the end instead of value_bool=true makes no difference either.
