Jandy 7620 2018-04-07 21:04
I used the iAqualink extended server outage as the impetus to finally take a step to rid my network of that device. I looked at several alternatives. The Jandy 7620 RS Serial Adapter was the first to arrive in the mail, and so I ran with it. I plugged it into my pool's main panel by way of some 4-wire alarm cable, and then plugged a new Raspberry Pi 3 B+ into that. It was really easy to set up and right now it's running the pool. I've implemented most of what I'll need and still need to work out a way to manage the RS panel's built-in scheduling system, but I believe the functionality is there.

If I was starting over, I would seriously consider the aqualinkd project that only requires a very cheap hardware connector and probably does everything I want.

And if I was going to recommend a system to a friend that did not want to write any code, I would probably recommend the Autelis. I actually got one of them in my frenzied state, but I haven't taken it out of the box (I would have if it had arrived before the 7620). Looks like it has a built in local web control interface - nice. I would probably recommend it over the 7620 - it's cheaper and has better connectivity options. It requires its own power supply, which could be limiting, but with the 7620, you pretty much need a computer attached, so the power issue still exists. The RP 3 B+ supposedly supports Power Over Ethernet (which is why I bought it) but apparently you still need to buy a separate "hat" for it which doesn't seem aavailable yet..
