I agree with everything you have said about the competing product. I would hope that most (like me) would not ask you for hardware support on a competitor’s device. That having been said, I have been using the TAIO model for 4 months now and yes, I have contributed to the open source project with my posts and with subsequent purchases from you (The RF Toy so I could hook up my light controllers along with the receivers and transmitter of yours. I also then purchased your Open Garage Door). While I may not have purchased the same amount of $$$$ products as your sprinkler controller, I have indeed been driven to your site and aforementioned purchases because I had never heard of Open Sprinkler before finding the TAIO device.
I for one appreciate and applaud your work and embrace every bit of it and will continue to do so in the future.
