LinknLink, Control All Smart Devices

I really enjoy using LinknLink to manage all my smart devices. Its AI assistant works reliably and supports many brands and smart home ecosystems. Setting up automations is straightforward, pairing devices is fast, and the interface feels clean. This one app nicely brings all my smart gadgets together.

I was able to complete the account set up after update

Can not complete making a home location on the app, so it makes the whole app and their products useless.

After the update, I was able to finish the account set up process and now testing my sensor I bought. I moved from one star to three stars.

Very poor all around

The emotion pro was pretty good when I got it a year ago. Since then firmware updates have broken it and you can’t configure in the app. Their solution is to uninstall the app but that does no good. Just got the ultra and it’s extremely slow and constantly shows a phantom.

Annoying app

And they think the rebuild is better?! The device screen is more confusing with the extra tab. Radio browser randomly added. What for?! We don’t need MORE clutter. Who asked for this? And why does TV have 2 Entity? What the heck does that mean? I have one device connected. And yeah the setup process is annoying too.
