What does these icons mean?

I had setup tinxy via Smart Configuration method. The device is working perfectly fine manually and from Tinxy app. But Google Home isn’t working. It used to work before.

Your devices are offline. That is why it isn’t working

The Grey WiFi icon shows that the device is Offline. But what does that other icon in black means, probably Hotspot or something?
Because whenever it shows, my devices are working with App

The hotspot icon means the devices can be toggled in offline mode
