    2017 HotSpring Limelight Glow Heater Leak

    AWESOME! Thanks for the info and quick reply. I think for ~$299 a new heater isn't a huge problem. I will check the jet body seals and see if they are damaged. That would indeed be a bigger problem.

    2017 HotSpring Limelight Glow Heater Leak

    Hey all, I have a 2017 Limelight with the ACE Swcg. It looks like I have a small leak at the heater that I am trying to diagnose. I tested the white stuff and it looks to be salt with Taylor kit. FYI I added the ACE after the fact and use the Scepter Salt Cell. It "feels" to me like the salt...

    Are there any Electrical Engineers on here?

    So Good news on the controlling the pumps. The secondary set of switches on the topside for the pumps are just momentary shorts on the 5v line. So I can get the raspberry pi in place this weekend and control the pump schedule. I wanted to be able to run all the pumps on high at least once a day...

    I am going to see if they have worked through what I am stuck on. I ordered their rs485 capture device. I will see if I can get more data.

    @Rattus Suffocatus @tucsontico @dschlic1 I got the logic analyzer hooked up and pulled data off of two pins at a time, so only the neighboring pins are in sequence. I don't know what the timing was between data Tx. This is where I am a little out of my depth. I have never written any code or...

    Half of the battle is finding the time. I have a good start, and the coding part should be pretty easy. If it isn't easy to read and write consistently, then you will be 100% correct. It just seems like with the simplicity of the button pushes, the ability to simulate button pushes should at...

    I think the more likely scenario is that the equipment to figure it all out and time to program to successfully get it to read back is < Buying the new controller like you said. Just need a bit of stubbornness.

    Thanks. The logic analyzer was picking up some square waves and was reading the data. It looked garbled, but having read how other hot tubs read out data, it may not be as garbled as I first thought. I just need a way to capture it reliably. I will see if I can narrow it down this afternoon. The...

    You could be my life coach with that kind of advice. I typically make a situation extremely complicated, break it, and then learn everything about it trying to fix it. Hopefully I can learn something useful long term out of analyzing these signals.

    I took some readings today with my oscilloscope and while I don't think it is extremely accurate. It should be in the ball park. Here are the basics: The line from the board has a coupler for another 3 button panel with no display. 10 pins Pin 1-2: 7.5V +/- 60hz (Could be +/- 1V to 2V...

    The waveform definitely looks like RS-485. I will need to see if I can get my logic analyzer to read RS-485. That would simplify things greatly. I will read up on the standard, so I can compare to the signal. Part of the message may be something else since it has a much larger Voltage...
