Support for Intex SJB-HS

[Monsardi]

Hello,
I have a intex sjb hs with salt electrolyse + jet streams.
Do you think it is possible to add this functionality?

all the best Peter

@Monsardi
The display of the SJB-HS looks different than that of the SBH-20, e.g. it has additional buttons. Without getting my hands on the hardware and spending some time with it it is impossible to say for sure.

Please have a look at the project DIYSCIP because it claims to support SSP-xxx and SJB-xxx models.

Hello
I also have an Intex SJB.
I connected the esp8266-intexsbh20 project to the pool.
I just have the problem that I can't turn the filter on and off.
When I turn on the filter via ESP, the bubble turns on.
The info what on/off is correct.
Also the temperature is displayed correctly

@mabeca96: That is very interesting. I did not expect that it would work at all.

On the assumption that the control principle of my project also works with the SJB model, some changes are required to address the different mapping of the control function like the bubbles. The approach would be:

• add a new config option to select the Intex model (SBH, SJB)
• support different control bit mappings for each supported model

Because I do not have a SJB I would prefer is someone changes the code, makes tests and submits a merge request. Otherwise I would have to dry code and you could test. My current lack of spare time will not allow me to do the latter, at least not before the summer is over.

Luckily there is another option: you could hard code the changes yourself. That way we will quickly know if it really works. Open SBH20IO.cpp and change the values in the enum FRAME_BUTTON. Look into the project DIYSCIP to get the correct values or just try out different values. You already know that the current value of the filter is your value for the bubbles.

Let me know if you can make it work this way and if yes, post the details of the changes you made.

[mabeca96]

I will try it with hard code.
Can you help me see the value of DIYSCIP?
Example
You: const uint16 POWER = 0x0400
DIYSCIP: BUTTON_POWER U5 | COMMAND_ADDRESS_S2
BUTTON_POWER COMMAND_ADDRESS_S0
#define U5 0x80
#define COMMAND_ADDRESS_S4 0x04

[Monsardi]

Thanks for jumping in the conversation. I can confirm that I have the same buttons/functions that work and the same that fail.
Pushing the bubble function triggers the jetstreams and the filter is triggered by the bubble button.
Of course there's also nothing that triggers the salt electrolyse.
I'm curious whether the hard code road will work!

[jnsbyr]

When I look into the DIYSCP code I don't see a definition for a bubble or a jet button and there seems to be no additional documentation other than the code and the schematic. So I don't have anything to compare or recommend.

Please assign an otherwise unused 4digit hex value that sets only 1 bit (1, 2, 4, 8) to one or more of the functions of FRAME_BUTTON (e.g. 0x0010) which do not work for you, build and try these functions. Should be around 16 possibilities - so this should not take too long. You can probably skip all values matching FRAME_TYPE::CUE (0x0100), FRAME_TYPE::LED (0x4000) and FRAME_DIGIT::POS_1 ... POS_4) if the display works for you. Either one of the remaining codes helps or it doesn't.

Beware that this way you might be able to send a code that triggers a function reserved by the manufacturer that cannot be triggered by the real panel.

Regarding functions the SBH model does not support like the electrolyse - if you can find the button code and it works consistently for you than let me know.

I found out the following code

const uint16 POWER = 0x0400;
const uint16 FILTER = 0x0080;
const uint16 HEATER = 0x8000;
const uint16 DESIFECT = 0x0001;
const uint16 TEMP_UP = 0x1000;
const uint16 TEMP_DOWN = 0x2000;
const uint16 TEMP_UNIT = 0x2000;
// const uint16 JetDuesen = 0x0008;
// const uint16 JetBubble = 0x0002;
// const uint16 F-C = 0x2000;
// const uint16 JetBubble = 0x0002;

what I am still missing is the display whether the disinfection is on or not.
Can someone explain to me where I have to set additional entries to control them from the MQTT (e.g. disinfection)

[Monsardi]

have you found out the missing entries?
Unfortunately I have no knowledge at all about coding so I can't be of any help.

[jnsbyr]

I found out the following code

Did you try the setting you posted by changing FRAME_BUTTON in SBH20IO.cpp?

If yes, please elaborate your results a little bit. Your current listing has some contradicting lines e.g. TEMP_DOWN and TEMP_UNIT are both 0x2000. Can it be that you do not have a TEMP_UNIT function? On the other hand you added some extra values. I assume these are the extra function of the SJB. What is "F-C"?

As soon as I have the hole picture I can add a variant for the SJB model and the necessary command support via MQTT.

[Monsardi]

F-C switches the display from fahrenheit to Celsius

[jnsbyr]

@Monsardi
Thanks for your reply. So "F-C" is the same as "TEMP_UNIT" of the SBH - no big surprise here. That leaves the contradiction that your "TEMP_DOWN" has the same value.

Could you please answer all questions from my last comment in some detail? I do not have a SJB - so without you input I cannot make the required changes.

[Monsardi]

Hi, i'm afraid I can't answer your other questions, as it is maceba96 who found out the rest of the code.
