Hey guys. I have a Four Winds Honolulu spa that we picked up a few years ago, and ever since I've owned it I've always wished there was a way to control it remotely (from a cell phone, etc). I see that some controller manufacturers are are putting out units that have this capability, but I wondered if there's anything out there that's universally compatible or retro-fit-able to units that don't have that capability from years prior. If not, is it because it wouldn't be possible to add this "adapter" to a control unit that didn't originally have one? Or is it possible and just yet to be released? For the record, my spa has a Balboa control unit - a "VS" something-or-other. I'd REALLY like to be able to wire a wifi adapter up to it and be able to turn the temp up remotely!!
