Hi! I have just connected my second Wi-Fi Smartthings hub today. I connected the main one yesterday with no problem. The second one took a factoey reset to acheive a connection. However, in the Smartthings app, both of my hubs are now “optimizing connection” and have been all day. I connected a hue bridge to the subhub one and all works great. The wi-fi works great too, but even though I am right next to my subhub, it still only stays connected to the main one. Has anyone have a solution so my hubs become stable? (I tried them for a few hours in my old house before moving out and they both worked no problem without the “optimizing connection” status.)
UPDATE: Finally, after about 14hrs they are now “working great”!
