Attaching older WIFI / IP devices to Smartthings Hub

I have some older WiFi / IP D-Link Smart Plugs & Cameras that have worked well for some time that are not recognized by the Smartthings Hub2. Can I work around this or do I need a different automation program to tie the Hub and other devices together?

if you D-Link Smart Plugs are Model DSP-W110 they work with IFTTT and all you need to do is create a virtual Switch/Plug for each then link them via IFTTT only downside its a one way connection meaning if you manually turn on the D-Link it will not show in SmartThings that its turned on.
