home internet conteolling devices

Generally it is a good troubleshooting technique to make sure the device is connected to the right network (your T Mobile Internet). Then if that for work reset the device. It’s a pain but is effective. 
 

Good luck!

It is connected to network and happening to every single device.  It seems like it is more of a problem with the app and internet rather than resetting every device, no?

Just for clarification, do you have home devices like Google nest thermostats and Blink cameras? Do they work? Do you have tablets and phones, do they work? Same with smart TVs? Do some devices work? Trying to diagnose a problem it is good to breakdown the issue to smaller chance. 

When you look at your T-Mobile internet app, what does your “Connection quality” read?

Tap on the “Network” link at the bottom. Do you see your network? 

Tap on the “Devices” link at the bottom, do you see your devices connected? 

Connection quality_ Excellent
Network is there
all devices are connected, but I cannot schedule any of them.  Only problem I am having with anything.  I can schedule nothing: phones, thermostats, fire tvs, roomba.  All connected, but everytime I hit schedule and try to input it times, it says device failed to upload no matter what device it is.

Thank you for your help.

ooooh, ok. Now I understand your problem diagnosis - can’t schedule any device. You will need to add a wifi router (T-Mobile Gateway > wifi router) then connect to the wifi router like a Netgear MR60. There are options in an external wifi router that will allow you to do things like schedule devices/services. the T-mobile gateways is either on or off (as I understand it). 

I hope this helps!

But I have been able to do it just fine threw the app with what I have until now.  Why would that be an option on the app and work prior and not work now?

I am unsure as I am not familiar with the technical aspects of your network. Sorry.
