I was wondering how you can control your gadgets at home from outside of your wifi across the internet without a static IP address? Do you have to buy a specific company's hub and then create an account with that company thus allowing your hub to poll (from your house) for changes? If so it means you are completely constrained by that companies online web interface and it makes the purchase of the hub very important. Is there a way to achieve home control across the web without such reliance on a 3rd party? Thx in advance.
