I was looking for a simple, lightweight, extendable (really extendable or easily programmable) and opensource software for building my own home automation system. I found WebThings Gateway and especially WebThingsIO community!
Recently I decide to change the FullControl business model from paid download to freemium ( free download and PRO version via In-App purchase ). Then I had to deal with a couple of issues: receipt validation, PRO version available for “older” users, In-App purchase validation flow. In this post we are going to discuss the last point.
