how can i move a speaker to another system

Maybe sign out the app and back in again with your new account credentials ...and just to clarify the speaker you are adding has been powered off and factory reset?

yup i tried that and yes i’ve factory reset several times now. This is amazing. All i wanted to do was unplug a speaker and plug it in somewhere else. I thank you for all the help you;ve tried. Sonos has been absolutely no help at all and i can’t be more frustrated. You can’t reach them by phone and when you try to chat, in the 3 days that ive been messing around with this there has only been someone available for an hour or so. He basically told me to update my phone and best of luck. Just aweful!    

Once you did changed the account you will certainly need to reset the speaker that you’re trying to add.. and it should attach to the account you’re logged into.

Note, as well as transferring the account there is the ‘change email’ option too in the "settings/account’ area of the app, but I assume you’ve checked that ..maybe also check your Sonos online account profile looks okay by logging in with the new credentials via this link:

https://www.sonos.com/myaccount/user/profile/

I clicked on the link you provided and on my computer I was able to log in and it says “account verified”. When i try to do it on the phone it comes back and says “email or password do not match our records”. I deleted and reinstalled the s2 app. When i tried to log in using the email and password that was “verified” it says “incorrect password or email” When i tried to “create a new account” it said “that email is alrready in use”.  I am logged in to the account to use the app, but then it asks me to log in again to connect the speaker it keeps on saying “account does not match our records”.   I even tried resetting my password. The screen is actually open on my computer that says the new password is verified and when i try to log in on the phone to install the speaker it says the email and password do not match their records

Personally, if I wanted to move speakers regularly between systems I would buy a Boost. Then take Boost and speaker(s) and just wire the Boost to the router in each location. Nothing to change. No hassles.

Edit - sorry just realised that you have systems in both locations

the way things have been going for this supposedly simple thing i don’t think i would want to buy or recommend anything to do with sonos

Please bear in mind that Sonos is designed to be a permanent home multiroom system 

Factory resetting and re-adding each time should be all that is required. The simplest solution would be to get another speaker  ....

John I think part of the problem is that i haven’t touched either of the systems since i originally bought them and now the original email that i had when i set up the systems no longer exists. I simply wanted to make 1 simple change. I just find it so frustrating that I can’t talk to an actual person on the phone to get help. The systems have had a few bumps but have worked just fine up to this point. The lack of support doesn’t make me confident that spending more money on additional items will help.

and yes i have factory reset the speaker.

I’m not sure what may have happened in your case as usually moving/adding a factory reset speaker to a different setup is a simple process, albeit forgetting the password and transferring your setup to a new account may have introduced some complexity, but it might be best now if you chat online to Sonos Customer Care via this LINK (partway down the page on the left) to sort out any account issues, as they are perhaps best positioned to see what accounts exist and are now in use.
