All lights on after plugging in MCU

[paulandrewcrouch]

• Pump model, for example S100202 (Square)
• 6 wires to pump, 4 to display (in a 6 plug)
• PCB v2
• Red LLC

• Software (from GitHub yesterday)

  Thought all was going well, Node MCU flashed, integrated into Home Assistant with MQTT, on the Wi-Fi fine, website loads ok. Soldered the cables onto the board and thought amazing, just need to plug in.

Sadly, display on the pump all lights/buttons light up and 888 on the display. Can access the web page but the buttons do nothing.

Any advice appreciated.

Have you configured the hardware in the web ui?

To the best I can…. because I don’t know which one to select I’ve tried the different 6 wire pump models and different 4 wire displays. Have I missed something obvious…? Thanks for the quick response.

You have a pump and most likely a Display belonging to said pump, right? Then There should also be a Model number somewhere on the pump, if not, send a picture, and maybe we can take some educated guesses.

Aha, I'm pretty sure you have a 4 wire on both ends. The spa manufacturer seems to throw in whatever they have on hand sometimes. In this case a 6-wire cable. So you should set both the pump and display to a 4-wire model. Both should be the same. Don't know which, but there is only 5, of which only 54138 and 54173 has hydrojets.

[paulandrewcrouch]

I was full of hope, but I'm definitely all out of ideas now, tried every option (together), lots of permutations if I try different pump from board (which I have tried a few). Even took it apart today to see if I could see model numbers but I don't know where to look. I must be so close, yet so far away!!

Thanks for you help though, much appreciated. Am determined to sort this.

[visualapproach]

Usually the number is on a big sticker on the outside of the pump.

Okay so you have a S100202. It's not listed so you may be the first to try it. I'll see if we can figure out what goes on. Call you back with advice.

That really kind. I wondered if I should swap some wires (like in the instructions) where the red is swapped over?

[visualapproach]

Hi again @paulandrewcrouch . From your last message I understand that you haven't checked the pinout. With that I mean checked which wire from the pump is TX and which is RX. Correct? Since there are only two combinations you can of course just try to flip them. But if there is more issues than just this, it would be beneficial to actually know that the wiring is correct.

How to find CIO TX (transmit line): Turn pump OFF. Disconnect both the ESP and display from the pump. Turn pump ON Use a multimeter to check voltage between GND and the data pins on the cable coming from the pump. The one with a reading more than 0V is CIO TX. Do not short the pins!

The CIO TX wire should now be connected according to your PCB setting. If using PCB V2 as in the picture, it should be connected to D2. The other wire from CIO (RX) goes to D1. DSP RX would be the same wire as CIO TX before we added the ESP module. So it goes to D5.

[paulandrewcrouch]

Ok, so tried a few different combinations today too (just checked and all works fine when plugged back in normally so nothing blown). Across the four active wires, I'm getting about 4.78V from all three (the 5V feed and the other two wires, presumably Tx and Rx). Same every time, all lights come on and stay on.

[visualapproach]

"Four active lines" is ambiguous. Did you measure whilst connected to the esp or as I suggested?

[paulandrewcrouch]

As you suggested, just measured what's coming out of the ribbon, nothing else connected.

When I power it up normally, all the lights come on, it bleeps, then then the control panel shows temperature. May a 3 second wait. Almost as if the CIO waits for some kind of acknowledgement / handshake? When the ESP is plugged it, it stops this handshake?

[visualapproach]

Okay, I guess there is pull-ups on the lines then. Very well, update via web ui to the beta version and go to page layzspa.local/debug-on/ You need to enter the address manually with the trailing '/' Let it run for a few minutes and go to layzspa.local/dir/ Click on log.txt and post the text here You may want to go to .../debug-off/ to stop recording

When 'take control' is not active the esp copies the messages between the display/cio. So it should work as long as the protocol is right. Serial 9600 is assumed in your case.

[visualapproach]

I don't know if you tried to flip the wires yet but if you didn't it is easier for now to flip them by going to the hardware page and select custom pcb. Then flip the pinout. 1/2 --> 2/1 5/4 --> 4/5

[paulandrewcrouch]

I’ve resoldered onto another board and also put in spade connectors so I can easily turn them. Yes tried changing the pins over, to no avail.

Am a bit stumped. Will try doing it in the software rather than the wires to see if it makes any difference.

could it be the LLC?

wrong PCB?

[paulandrewcrouch]

Tried the software change - no difference. I feel I've done something wrong, but don't know what... Connecting the PCB, Node MCU and LLU seem to not allow an acknowledgement signal, yet log.txt didn't put up any activity.

[visualapproach]

Make the hardware test to see if the device is okay.

[T1gg1]

Same Issue here Wemos D1 mini with blue LLC. Changed the LLC, same issue. For one minute the esp shows the correct temperature. I clicked some switche but they switched back. After I changed the hardware config, the bubbles startet for about 3 seconds. But I could reproduce it :D

If I switch to a 4 Pin model in the config, then the ESP is very slow and sometimes it won´t start up

[visualapproach]

@T1gg1 you didn't state what pump model you have.

[T1gg1]

Same as paulandrewcrouch

Ok can you log when set to a 4-wire in config. And use the latest beta version uploaded an hour ago

[visualapproach]

Weird data from cio and nothing from dsp... Does anyone of you guys happen to have a logic analyzer?

[T1gg1]

@visualapproach yes I have one

[visualapproach]

Cool, would be helpful to see logs on the two data wires without the esp present.

[T1gg1]

digital.csv I did it threeway so I connected channel 0/1 to display and pump. It started, I turned it on, turned the bubbles on, turned bubbles off and turned the complete pump off. I hope that help. Should I connected it otherway? Channel0 = fourth contact Channel1 = third contact

[T1gg1]

I don´t know if that help and how but I hope so :D

[visualapproach]

Can you post a screenshot of the waveform graph where the timing is visible? I looked at the data in excel but don't have a good program to view it in present form and I couldn't be bothered to make one. It looks like a higher frequency than the usual 9600 baud. More like 57600 from a guesstimate

[T1gg1]

Like this? With async serial 9600 analyzer it shows the third picture I tried it with 57600 and then it shows the foruth picture

[visualapproach]

nice, what program are you using and what's the filetype of the samples?

[T1gg1]

Logic 2 Filetype is .sal

[visualapproach]

okay, I'll look at it when I have time. If you post the file :-)

[T1gg1]

Session 0.zip I put the plug in, activate it, reduce the temperature, start the bubbles, end the bubbles and deactivate it and pull the plug

[visualapproach]

Thx, it seems like another protocol than the rest of the models. I'm interested in cracking it, but its not obvious to me how to go about it yet. Are you able to see the chip names and we may be lucky to find a datasheet.

[paulandrewcrouch]

It’s so strange that a production line pump would have such variations. I did wonder if it was simply baud rate.

Also so annoying following your tremendous work we seem to have a model that for some reason wants to play differently.

Thanks for all your support so far.

[T1gg1]

@visualapproach for the display it is a esp wrom 02??? the rest is completely sealed. I can not see the backside. Thank you for your help

@paulandrewcrouch as usual. If you find a way to not use their cloud and app, they will find a way that you have to.

[paulandrewcrouch]

I did wonder what bypassing that would do. Later models appear to still work though, so we just have an odd variant?

[wyliecoyoteuk]

Not sure if this will be of any help but... I have an earlier pump with an ESP wifi module, #54184 6 wires Currently using V4, PCB v2 and pre2021. Remote control works, but none of the buttons or display work.

[visualapproach]

I didn't realize we were talking about wi-fi pumps. Can you make a simple drawing of how it's connected? Will probably not make any difference, but I'm just curious.

[paulandrewcrouch]

4 wires from CIO to DSP, then 4 from DSP to wireless chip. Perhaps I could just tasmotize the chip (with a backup) that's already there?

[paulandrewcrouch]

Sorry 6 from DSP to chip.
