Current draw from Jandy 24 volt DC AUX

[markcrompton]

Looking to power a remote WiFi switch from a Jandy AUX (RS4 with 2 spare AUX). I’ve read the Jandy manuals, and while can see relays drawing 100mA the note also shows the 2 speed relay consuming 200mA. Want to know how much current can I source without blowing the driver chips?

The device I have is a 4 channel switch from Amazon, similar to to SonOff (but cheaper, $18). I’m using it to control/replace the SPA switch which is causing my control panel issues. Right now under testing it’s powered by a 5v usb cable, but I want to hardware it into an AUX if possible (yes I could add a 120 outlet to the panel and leave the PSU). Max draw from the device is <200mA, while nominal draw is 115mA (tested connected to a 9v battery).

Thx

Here is bump for more eyes.

Best way to know is to look at the specs for the components on the control board. Don't think I have one anymore from my old Jandy RS system but I'll check. What is the issue with the spa switch? Is this all you're trying to fix or do you want to add additional controls?

The spa switch is causing the control panel to lock in spa mode when a couple of the buttons are pressed. Only restoration is power cycle. Only happens when I use the One touch when the spa switch is connected. Remove the spa switch and everything is OK. Really the spa switch needs replacing. This solution also adds Google/Alexa automation.

The panel shows 1amp on the 24v circuit (found that after the original post), so I should be OK to wire off the aux. I've tested through external power and the device works as intended (isolates the spa switch). I could add a 110v outlet to the panel instead and continue with the 5v usb feed, but that's a but messy.
