I sure am! It works great. Right now I just have buttons set up in Home Assistant to fire a MQTT message to alter the speed, and I no longer have to open the iAqualink app, hope it's connected, click through screens, etc. Two taps and I'm there. Pump is a Jandy VSFHP165JEP.
I have the recommended
FTDI cable in the aqualinkD wiki. I would think once it's up and running, there wouldn't be any need for updates. I say that because in the way I'm using it, it's just a gateway from Home Assistant to the RS panel. All my "advanced" control, monitoring and logic I can do in Home Assistant, and aqualinkD just acts as the translator. I'm still using the scheduler in the RS panel.
That said, I have it running on a Raspberry Pi, which runs off an SD card. I don't expect that to last forever. I have the file system in read-only, and a few notes on how to rebuild it. I suppose I should make a backup copy of the card one of these days.
I picked up one of the Orbit outdoor sprinkler controller boxes that has a GFCI built in, and mounted the Pi inside. Super quick and easy.
