Easytouch and Spa-Side Remote problems

[TBan]

Anyone ever come across this issue, where the Easytouch system (PS4 in my case) intermittently turns the Spa-Side feature off by itself?

I have a DIY circuit designed with optocouplers connected to the is4 terminals, with a wireless receiver momentarily triggering the is4 ground terminal to one of the is4 control terminals when a signal is received. When I initially turn on the Spa-Side Remote feature, it all works perfectly. But after some random period of time (sometimes several hours, sometimes just a few minutes), it stops working due to the Spa-Side Remote option switching Off in the Easytouch menu. If I turn the feature back on at the ET panel, everything is fine again until it turns itself back off.

Here's a rough diagram of the circuit

It's a pretty simple design. I used optocouplers to keep the is4 terminals isolated from the ESP32 controller's power circuit. All 4 channels work as expected when the Spa-Side remote function is turned on, I just can't seem to keep it from switching itself off after a period of time.

Yes. same issue here. Just noticed it in the last couple months. May have started up to 6 months ago. I just updated brick to 5.2 build 738 Rel. 2 days ago to attempt a fix. Did not fix it. It may have followed power outage? or when I turned breaker off to replace equip parts? or when main panel was turned off for solar panel installation? All these happened in last several months. I will try flipping breaker and see if it helps and report back. Could the reoccurrence of your issue have followed an outage?


Reporting back -> did not fix it

@TBan

Most spa side remote problems are due to intermittently bad spa side remotes. They get corroded inside which often makes them intermittently turn things on or off.

When I moved your post from an old thread, it may have caused us some confusion about your specific problem. How about telling us again about the problem you are having.

Thanks,
