Since this morning, one of the device had a red flshing led. I disconnected and reconnected it. No change. I restarted my whole internet (box) connection. Still the same. 

I thought I would remove it from the Deco network (with the Deco mobile app) and add it again. I could remove it but see no option to add a device :-(

So, I just thought I would reset the device. I did. Now I have a blue flashing led and have no idea what to do.

Any help will be welcome to understand what the blue flashing led means + how do I add and reconnect that device to the existing Deco network.

Thanks much in advance for your help.
