You are trying to install a version 2 device handler into a version one environment (i.e., the beta version version the current version). It will not work and the new version is the only one that (should) supports the LB230.
Try the following. (This is in-lieu of a complete remove and re-install).
Replace the contents of the current Plug/Switch Device Handler with the content of the file “(Cloud) TP-Link Plug-Switch.groovy”. The device handler page will then have:
davegut : (Cloud) TP-Link Plug-Switch davegut : (Cloud) TP-Link Color Bulb
Replace the contents of the current Smart App with the content of the file “TPLink Cloud Connect V2.groovy”. The Smart App page will then have:
davegut : TP-Link Cloud Connect
