4 years ago Can you explain a little more on what you have connected & available, and what you're trying to do? But few pointers that may help
-
Best way is to simply use the serial logger (from this repo) and log what happens when you control the equipment using jandy/pentair controllers.
-
You should really be looking at the raw hex from the bus, not the decimal conversion that your posting, that way you can be sure of the actual start / stop packet(s).
-
(reason for above) Pentair inteliflow and Jandy protocols are different and will collide / overlap on the RS485 bus, so you can get a Jandy byte sequence in the middle (or overlapping) a Pentair byte sequence so making things very difficult to decipher.
-
If you don't have some form of controller to monitor, Jandy has some very old PC based simulators that can control some equipment using a USB2RS458 adapter. I've decoded (some) equipment I don't actually own by having an old PC with RS485 adapter running Jandy simulator software controlling equipment while also having a Raspberry PI with RS485 adapter running the serial logger within this repo. The Jandy simulators are really crap and 1/2 don't work well, but it's pointed me in the right direction at times without having to buy equipment.
-
If you go through closed threads here and aqualinkd forum and start picking out log files people have posted, you'll probably find everything (or a lot) you need to know on the pump protocol from other peoples systems. But I have not spent the time to fully documented the Pump protocols yet, I've really only looked / deciphered the status messages.

@sfeakes I was hoping to ask for your insight base don all the work you have done here.
I am struggling to figure out why I get inconsistent results when powering off and on my Intelliflow pump. After spending a few days looking at your code I have the following. It works but not consistently and it makes me think my timing or sequence if off or more importantly I am missing a packet that needs to be included.
Do you have any ideas?
To Power On the Pump into Program 3 Packet 1 (Set to Remote) 165,0,96,33,4,1,255 Packet 2 (Set Program 3) 165,0,96,33,1,4,3,33,0,24 -- 175ms after previous message Packet 3 (Turn Pump On) 1165,0,96,33,6,1,10 -- 175ms after previous message
To Power Off the Pump from Program 3 165,0,96,33,4,1,255 165,0,96,33,1,4,3,33,0,0 -- 175ms after previous message 165,0,96,33,6,1,4 -- 175ms after previous message
