Re: Hot tub / spa / jacuzzi controller

Hi Jean, I have a new hottub and want to add it to my home automation system. I've got a similar spa (also Balboa, https://www.tubs.fr/balboa-gs510dz-control-system-p-2306.html ). The control system has 2 free rj45 ports (probably for extra touch panels). So I want to do the same as you did, but st...

Re: Hot tub / spa / jacuzzi controller

Hi, I know this thread is a little old, but I am attempting a very similar project. I hooked the oscilloscope up to the 10 pin panel, but need some help interpreting the data. I am going to get pigpio set up tomorrow and see if I can get more data. I will report back if that's alright with you? Sou...

Re: Hot tub / spa / jacuzzi controller

Hi JeanL, Thanks for sharing the source for the pigpio C library. I've tried to use it for my project (I was trying to synchronize the camera frame taking and strobe pulse generation). Can I use gpioSetAlertFunc() function? Do you have any experience with it? Thanks. Terry I don't have any direct e...

Re: Hot tub / spa / jacuzzi controller

Ok, well let’s see what I can find out. Any pointers on how you did this would be great. I’m not the best when it comes to signals but I learn fast. Maybe an example of your code based on your findings and how you got the times etc. Thanks again. My code won't be of any help for you, because I didn...

Re: Hot tub / spa / jacuzzi controller

It has been awhile since i looked at the functions available in the .NET classes, but in C# IOT, there is event for detecting rising and falling edge, i have tested these a few moments ago with a simple circuit and push button. Here is my code. So i can definitely tell when an GPIO (Input) is going...

Re: Hot tub / spa / jacuzzi controller

Thanks JeanL. I ordered a cheap signal analyzer from amazon. So has anyone got some code samples of what they are doing once they understand the clock signal rate and signal pattern? It’s been a long time since I done this, but was hoping to see come code. It’s raining now, so I won’t be messing wi...

Re: Hot tub / spa / jacuzzi controller

It shouldn't be hard, once you know which lines hold +V, ground. pigpio has a signal analyzer called piscope. Once you install that on your pi, and connect the GPIOs to the lines from your connector (and the ground), piscope will show you in real time the values it sees on each of the GPIOS. This sh...

Re: Hot tub / spa / jacuzzi controller

I am wondering if i can tackle the same project. I am curious how Jayfun got on doing this project? Have we any examples on how to read signals using the PI. I have an RJ45 connection, so i will try drive them high with the PI and a resistor when i get a chance, but the main goal will be to have my...

Re: Hot tub / spa / jacuzzi controller

Yep, it looks like you're going to have to poke around to find out what's what. And yes, nothing's better than a signal analyzer, the one you showed looks really interesting. Just make sure you can go high enough in frequency so you can look at the clock signal. It was 40kHz in my case, but it might...

Re: Hot tub / spa / jacuzzi controller

@Tayfun, yes, the pinout you describe is correct for my jacuzzi. As for your question about setting the temp: my jacuzzi has a weird temp control mechanism: there's only 1 button which you use both for increasing or decreasing the temperature. So, if you press the button, the temp display blinks, if...

Hot tub / spa / jacuzzi controller

Just wanted to post a report on a hot tub project I just finished in case other would be interested. Contrary to what most people are attempting to do on similar hot tub projects, I wasn't trying to replace the main controller in my hot tub (an old Caldera Alpine, 1998). Everything works just fine. ...
