If you set up your Bond to use Google Home, the Google Home app can have guests / members added for on screen controls (of device types that Google provides on screen controls), and / or voice assistant integration.
I don’t have any smart blinds, personally, but the Bond staff and other community members here have indicated in the past that some of the blind and shade controls are available by voice only with Google Home, if I read them correctly. Not sure if Google has changed to allow on screen controls of blinds / shades yet?
As far as guest control of the Bond devices from the Bond app, I believe the company has not made a way to run the app without signing in. I also, from testing personally with a “dummy” / old login do not believe that you can create a second / guest account and still have control over the same Bond Bridge as your primary account; they seem locked to one account.
I get around this limitation with a setup that I don’t expect most people to pursue - any of my Bond controlled devices that I want guests (or myself!) to be able to control regardless of app access, I create integrations with my third party smart home controller (ISY) and use Harmony (via Hue emulator) and/or Insteon 8-keypad remotes to allow physical control.
That being said, if you wanted to allow your guests to log in under your Bond account on their devices, that would work (though also gives them access to the devices when they’re no longer at your home).
@merck , did I overlook something for Guest access (no login) through the Bond app, only while on the same network?
