It's kinda defensive in an 'I'm smarter than you' way. Replace "actually did think" with "thought." "Actually" says "no you're wrong." Remove "before you even suggested it." Saying you did it first attempts to position yourself as smarter. Adding "even" diminishes it. Making those changes, you end up with a less insecure, less posturing version, "I thought about integrating it into houseSYSTEM, but I decided that it’s probably best to keep them separated at least for now."
