As long as the “Terms of Service” apply, then SmartThings is reserving the right to charge any fees, any time, with no compensation for your investment (product purchases and setup efforts).
I’m concerned, also, that purchasers of SmartThings are not made more aware of these Terms BEFORE purchase; but that is typical, of course – who reads licenses and terms before clicking “OK”, anywhere?
A relevant quote from the Terms of Service:
We are constantly trying to improve our Services, so these Terms may need to change along with the Services. We reserve the right to change the Terms at any time, but if we do, we will bring it to your attention by placing a notice on the Services and/or by sending you an email.
If you don’t agree with the new Terms, you are free to reject them; unfortunately, that means you will no longer be able to use the Services. If you use the Services in any way after a change to the Terms is effective, that means you agree to all of the changes.
Does SmartThings cost anything?
SmartThings reserves the right to require payment of fees for certain features of the Services. Should you elect to subscribe to such features, you shall pay all applicable fees, as described on the Services in connection with such features. SmartThings reserves the right to change its price list and to institute new charges at any time, upon ten (10) days prior notice to you, which may be sent by email or posted on the Services. Use of the Services by you following such notification constitutes your acceptance of any new or increased charges.
Will SmartThings ever change the Services?
We’re always trying to improve the Services, so they may change over time. We may suspend or discontinue any part of the Services, or we may introduce new features or impose limits on certain features or restrict access to parts or all of the Services. We’ll try to give you notice when we make a material change to the Services that would adversely affect you, but this isn’t always practical. Similarly, we reserve the right to remove any Content from the Services at any time, for any reason (including, but not limited to, if someone alleges you contributed that Content in violation of these Terms), in our sole discretion, and without notice.
In other words, there is “definitely” no protection for us customers of SmartThings against major (or minor…) changes to the system/service, including fees of any amount they decide to implement.
