Hey folks. I understand not too much interest in this one (but it's on my list of connecting everything in the house I can to C4). Nonetheless, I wanted to provide an update for any that may be interested and the reason for the delay in releasing a beta. I ran into a snag with my test unit that has delayed the release. To elaborate, I noticed my wifi module was dropping off of the network every 2 to 3 days requiring me to power cycle the tub itself. When this started happening, I delayed the beta release as I was afraid I may be sending commands to the module causing it to get in a bad state. After a couple of weeks of investigation, I have found that others were experiencing similar issues simply by using the Balboa iphone app (and sure enough, I reproduced the issue with my iPhone app). After talking with Balboa support, they suggested I have the module replaced. So, long story short, I had a new wifi module installed on 4/18. I'm going on three days without any hiccups (thanks to the EV ping module to notify me as soon as the thing goes bananas). I'm going to let it run for another few days and if no problems I'll get the driver release out. Just don't want to release something that may cause your wifi module to fail. And yes, there will be a 4Store app for this one. Even though it does integrate with the Pool proxy (and navigator interface), the app will provide more functionality tailored to this particular spa. Thanks and if anybody out there has a customer that would be interested in testing, please let me know. Eric
