Add suport for jacuzzi 335 #1

Move from this thread https://github.com/garbled1/pybalboa/issues/11

HyperActiveJ commented 1 year ago

Debug code is in to capture the data from the new messages and initially pass to existing functions. Several button types have been identified and will be added. Second pass on status message decoding is in process to identify differences in field ordering.

HyperActiveJ commented 1 year ago

@jackbrown1993 I pushed a quick filter fix if you have a chance to run it. I may be able to get the status message fix in as well.

HyperActiveJ commented 1 year ago

The fields are more different then first pass guess made them be. In the status message I don't see the time at all. I do see fields correlating well to the set temperature, jet state, heat state, actual temperature, and what I think is the active display data. If the new code removes the '10 bf 17' warnings and cleans up the output then send a single long capture with the temp set point going up up up till heater turns on then down down down till heatertirns off, jets one on, jets one off, jets 2 on, jets 2 off, set time to a different time, then set time back, set date to a different date, then set date back. At each change we should see an info message printed with one or two fields changing. From there we can deduse the remaining data. I'll commit a change to remove the invalid status printing so it's just the info message.

jackbrown1993 commented 1 year ago

I am at work but just tried to run the script and got an error after the first few messages as attached. Error.txt

HyperActiveJ commented 1 year ago

Hopefully fixed, give it another try. Good news is that it looks like it's going thru the process of attempting to get a channel number assigned to the client so you have a time slot and don't conflict with the panel when responding on the bus.

jackbrown1993 commented 1 year ago

Yep, just found the error in the code and then noticed you had pushed a commit :) I just run the code for 2 minutes and 10 seconds and didn't get much output as attached. Capture 1712.txt

jackbrown1993 commented 1 year ago

C4 updates are every minute, just timed a couple.

HyperActiveJ commented 1 year ago

Interesting hmm. Well that some good data at least. Bad crcs can be due to a bad wireless connection dropping data. More data makes more patterns apparent, so send more. I have some theories from what I've see but I need a full test set to run.

Long output.txt

HyperActiveJ commented 1 year ago

Looks like enough to make a first stab at it. All the button identifiers are there, I'll add code to the next test to validate by setting the temp up 3 times then down 5, then jets 1 on, jets 1 off, jets 2 on, jets 2 off, with 5 seconds between each. Do you have a "clear ray" button and function? As for decoding the it seems like first byte of the status message is minutes, the second is unknown, third is const, forth is temp sensor a, 5=set temp 6=pump state, 7=fixed, 8=const, 9=unknown, 10=temp sensor b, 11-15=const,16= current menu, 17=menu data. I have an initial decoder to convert the encoded values to human readable and display. Will push as soon as i can.

jackbrown1993 commented 1 year ago

Sure - appreciate your help on this and will send you some coffee/beer tokens. Yes, I have clear ray, will capture the button press when I’m home in an hour or so. Not sure the button actually exists but will check and confirm.

HyperActiveJ commented 1 year ago

No worries, I haven't been home so I'm doing this all from my phone, so its a bit more cumbersome then ideal.

jackbrown1993 commented 1 year ago

Clear Ray button: Got Button Press x7E 06 10 BF 17 0F 56 7E Lights on / off: Got Button Press x7E 06 10 BF 17 11 0C 7E Lights change colour: Got Button Press x7E 06 10 BF 17 12 05 7E

jackbrown1993 commented 1 year ago

I can send commands to the hot tub using the below code which appears to work OK

BTN_CLEAR_RAY = 0x0F
BTN_P1 = 0x04
BTN_P2 = 0x05
BTN_TEMP_DOWN = 0x02
BTN_TEMP_UP = 0x01
BTN_MENU = 0x1E
BTN_LIGHT_ON = 0x11
BTN_LIGHT_COLOR = 0x12
message_length = 0x06
data = bytearray(8)
data[0] = M_STARTEND
data[1] = message_length
data[2] = 0x10
data[3] = 0xBF
data[4] = CC_REQ_ALT_17
data[5] = val
data[6] = 0x67
data[7] = M_STARTEND
jackbrown1993 commented 1 year ago

@HyperActiveJ any advice on where I should start in decoding the status messages?

jackbrown1993 commented 1 year ago

https://github.com/jackbrown1993/Jacuzzi-RS485

I have Temp and Set Temp being read and sent to MQTT...still very hacked together but it's reporting the data.

Sorry I disappeared! Had some urgent things come up. Looks like you got the temp stuff i forgot to push before i left in and it's working?

jackbrown1993 commented 1 year ago

No worries! Temp is working but using a manual lookup array....it works as per below:

https://github.com/jackbrown1993/Jacuzzi-RS485/blob/master/app/jacuzziRS485.py#L62 https://github.com/jackbrown1993/Jacuzzi-RS485/blob/master/app/jacuzziRS485.py#L99

I also have the ability to send button commands to the hot tub, by sending defined HEX values as per below:

https://github.com/jackbrown1993/Jacuzzi-RS485/blob/master/app/jacuzziRS485.py#L40

Next steps I would like to be able to read heat and pump status if you have any advice :)

dhmsjs commented 1 year ago

Hi guys -

Late to the party I know. But I have just posted the actual decryption algorithm. Tested even!

See https://github.com/dhmsjs/jacuzzi_decrypt.

I'm pretty confident this is the real algorithm, but if you find any issues just let me know.

It should clarify your analysis of the panel status message fields. I am also trying to figure out the same but don't have an "encrypted" controller in my J-235 tub, so I can't do any testing myself. I am interested in seeing what you can tie down.

HyperActiveJ commented 1 year ago

Looks like a more valid solution. I'll see what I can do with it when I have some time.

dhmsjs commented 1 year ago

Somewhat academic perhaps, but this looks interesting:

If I add support for the CC message type to the decryption algorithm, with the decrypt key1 value = packet[5] XOR 0xDE, as in:

    # Encrypted packets have an extra byte that we use to form the first key value
    packet_type = packet[4]
    if packet_type == 0xc4:
        key1 = packet[5] ^ 0x19
    elif packet_type == 0xca:
        key1 = packet[5] ^ 0x59
    elif packet_type == 0xcc:
        key1 = packet[5] ^ 0xde
    else:
        # Done if not an encrypted message type
        return packet

then a "decrypted" CC message has these values:

225 - Nothing Pressed (0xE1) decrypted = 0x00
238 Clear ray button  (0xEE) decrypted = 0x0F = 15
229 Pump 1 Button     (0xE5) decrypted = 0x04
228 Pump 2 Button     (0xE4) decrypted = 0x05
227 Temp Down         (0xE3) decrypted = 0x02
224 Temp Up           (0xE0) decrypted = 0x01
255 Menu              (0xFF) decrypted = 0x1E = 30
HyperActiveJ commented 1 year ago

I just threw it in a test program and it certainly seems like it works, im refactoring around it now. I should say it seems like Jacuzzi/Sundane/Balboa is callign it 'encrypted', its really more like 'encoded'.

jackbrown1993 commented 1 year ago

Happy to also do some testing when you have a branch / PR setup.

HyperActiveJ commented 1 year ago

I've converted most of the field sover to the new version. Im still getting odd results with Temp 2 having offset when the heater is running. Otherwise im close to one for one replacement. I have to run some errands, i'll get a branch up when i can.

dhmsjs commented 1 year ago

So here's my experience with the second temp sensor on my J-235. It acts like it is in the piping just before or after the heater. So when the pumps are idle it will drift to a lower temp than the actual tub temperature, but as soon as my pump 1 comes on (which is also the circ pump), then the temperature quickly comes up to within a degree or so of the tub temp.

I also have a bit which comes on whenever the pump is running. Not the "Pump 1" status bit, but another, undocumented one further down the status message. That one seems to me to be the flow sensor.

And by "undocumented" I just mean that the Prolink app does not try to read it.

dhmsjs commented 1 year ago

@jackbrown1993 I've been reviewing your discussion above and it looks to me (as @HyperActiveJ pointed out) that your system is probably not "encrypted". Do you know for sure it is?

In any case what I see here is that HyperActiveJ's "encrypted" status packets have an entirely different format from my unencrypted status packets (I have a Jacuzzi 2021 J-235). By "format" I just mean how the bytes for temperatures, pump status, time and date, etc are arranged in the message packet.

I wonder if your status messages might be more similar to mine than to an "encrypted" packet. I looked at some of your captures but they seemed to be focusing on button commands, not status messages so I didn't find what I was looking for.

The snippet below is from my notes describing my "Panel Update" status messages (type code = 0x16). These are similar in function to the encrypted 0xC4 type, but clearly their formats are completely different.

jackbrown1993 commented 1 year ago

@dhmsjs don't think my packets are encrypted although it's been a while since I looked at this, would love to get this working reliably for my hot tub, did you make any more progress for yours?

dhmsjs commented 1 year ago

@jackbrown1993 I have a working jacuzzi.py at https://github.com/dhmsjs/pyjacuzzi which (like @HyperActiveJ's work it extends garbled1's pybalboa (https://github.com/garbled1) as well as work by ccutrer (https://github.com/ccutrer), and others.

jacuzzi.py does not yet support the maintenance timers (water, filters, cleaRay) but it does display and control most everything else that my J-235 has. I have a simple console app to handle the UI for now. You might try that out to see what works and what doesn't with your tub. I would be interested to know how it goes since my only test bed is my J-235.

My long-term objective is to integrate jacuzzi.py into HomeAssistant. I haven't done any of that work yet. Doesn't look to be too difficult though.

Another spa owner has also been seeking to control his Jacuzzi hot tub directly. He recently had to replace his (non-encrypted) main control board and the replacement was an encrypted type. That's how I got involved with the encrypted versions. But since my tub is not encrypted that other owner has to do all of our testing.

It is somewhat surprising to me how different the message packets are for each hot tub brand (Sundance, Jacuzzi, Balboa etc) given that they all seem to use Balboa controllers. The RS485 protocol is consistent across brands and there is a lot of shared code apparently, but also quite a bit of differences. Not sure why -- maybe to make sure users can't easily use hardware for one in another brand spa?

jackbrown1993 commented 1 year ago

@dhmsjs Just tried your code and it shows temp and set temp correctly when connecting to my Jacuzzi J335. Will have a bit more of a play and report back :)

jackbrown1993 commented 1 year ago

@dhmsjs are you on Discord, be good to setup a space to discuss a few bits.

dhmsjs commented 1 year ago

I am not (yet anyway). But email is dhmsjs at sbcglobal dot net.

jackbrown1993 commented 1 year ago

Thanks, I don't seem to be seeing panel update messages reflect reliably / quickly so trying to figure that out, if I change set point temp it doesn't reflect in the UI reliably / consistently.

Jack.

dhmsjs commented 1 year ago

On my tub (as seems common with most) the status updates spam out every second or so (or more). jacuzzi.py has a has_changed() method that remembers prior checksum bytes and ignores a new packet unless it has changed; you won't see status update packets unless they have changed.

I suspect your tub is spamming those status packets too, but if it were not, that would explain why no regular update.

The other thing I see is that the Prolink box itself seems to essentially go to sleep randomly. When it does you just cannot connect via WiFi until it wakes up again. Are you using the Prolink interface or a generic WiFi-to-RS485 connection?

jackbrown1993 commented 1 year ago

I am using a WiFi-to-RS485 connection - https://www.amazon.co.uk/gp/product/B097C8PT6F

dhmsjs commented 1 year ago

Well that is good to know. That means all of the initial work to establish the connection is purely from balboa.py. I've only used the Prolink module though I'd like to move away from it eventually anyway.

You might try adding some more log messaging to help find out what is causing the delay. Standard python logging should work and show up in the message window.

jackbrown1993 commented 1 year ago

I seem to be getting 0x23 messages every 10 seconds, not seeing constant 0x16 messages, as below, will check again with previous code I used to see.

The 0x23 messages are LED status messages. They are showing up because maybe your lights are doing the automatic changing thing right now?

Because jacuzzi.py is suppressing duplicate messages you will only see 0x16 messages when something changes -- which at a minimum will occur each minute, as the currentMinutes value changes.

dhmsjs commented 1 year ago

The "Requesting Module ID" message comes up whenever (I think) balboa.py loses the WiFi-to-RS485 connection. So it looks like the connection drops, then reconnects. I also see this with Prolink, but perhaps not as often as you are seeing there.

jackbrown1993 commented 1 year ago

@dhmsjs Yes odd that, is your plan to keep your pyjacuzzi repo into the HASS integration?

dhmsjs commented 1 year ago

Nothing so lofty; I just want to monitor and control my tub from my HA instance. If others can also use it to do the same, great!

Something I thought I should point out to you is that Jacuzzi's Prolink boxes always seem to use RS485 bus address 0x0a, whereas the general Balboa connection sequence is for a device to request an address from the controller and then use that. My jacuzzi.py isn't doing any of that specifically (though it may be happening in balboa.py; not sure).

In any case all of jacuzzi.py currently assumes it has a bus address of 0x0a.

The controller sends out status messages to bus address 0xff -- I suspect that is meant to be a broadcast address that all devices listen to. But if jacuzzi.py sends commands from bus address 0x0a to the controller and the controller hasn't established a connection with the device at address at 0x0a, it may decide to ignore those packets, or try to negotiate a connection, etc. I've never studied that much because it wasn't needed for me to get jacuzzi.py to work with the Prolink box.

With your WiFi-to-RS485 bridge we're in somewhat uncharted waters here so what you discover may be helpful in understanding exactly how the controller behaves.

jackbrown1993 commented 1 year ago

@dhmsjs I am going to incorporate some of your code in mine. Will provide credit to you, I am facing issues with your code which I suspect is based on the channel selection, looking at my existing app and code I seem to be using channel 17.

@dhmsjs I have opened a pull request on my own repo on the below URL, I will also soon be opening a pull request for home assistant integration.

You may also find ProlinkMessageTypes.txt (in my docs subdirectory) to be helpful for showing the differences between Balboa and Jacuzzi message packets.

For @HyperActiveJ this is what I currently have captured regarding the format of an encrypted panel status message.

Day of month seems likely correct, but month number still remains a bit perplexing to me.

Message Type: PanelUpdate (for "Encrypted" Jacuzzi Controllers)

From HyperActiveJ:

           possibly combined by XOR with byte 19

        DAY_SHIFT =  3 #Shift date field 2 by this amount to get day of month
        -- i.e. day of month is bits 7-3 of the byte -- looks possibly correct

        MONTH_AND = 7  #Shift date field 2 by this to get Month of year
        -- i.e. month number is lowest 3 bits of the byte -- only allows for month 0 thru 7 (?)

        day = (data[DATE_FIELD_2] >> DAY_SHIFT) 
        month = (data[DATE_FIELD_2] & MONTH_AND)

@dhmsjs what is the sacrifice of not having the has_changed function, were you seeing issues with the duplicate messages being processed?

dhmsjs commented 1 year ago

For me the value of has_changed() was only to be able to ignore the regular flood of duplicate panel status messages that spam out roughly each second, so that I could focus on only the status messages showing an actual change in state.

jackbrown1993 commented 1 year ago

@dhmsjs understood, I have removed that function now as it was causing me issues with channel assignment.

I have made some progress on my branch, it correctly identifies and sets the appropriate channel which seems to be 17 for me. Pump controls are confusing me a little bit, why does pump 2 have two 'on' states in the UI?

dhmsjs commented 1 year ago

Depending on the spa model, pumps may have several speed levels. The message packets (on my J-235 at least, but I suspect it is a general solution) use 2 bits to report pump state. If the pump has multiple speeds then 2 bits can support up to 3 separate speeds, as well as off. When the pump only has simple on/off control, the additional bit is not really needed. The way pybalboa managed this was to set up an array of possible pump states, and then populate that array based on the config information the controller reports during the initial connection negotiation.

Jacuzzi spas don't seem to have this dynamic configuration feature so their configuration needs to be static instead.

My J-235 has no pump 0. Pump 1 is the jets pump; it cycles through off-low-high state. My pump 2 is the blower for injecting air bubbles; it can only be on or off.

As far as the UI is concerned, I'd have to study it to know for sure, but likely it was just a way to keep pump 2 from displaying as "low" or "high" when it could only be "on" or "off."

And in fact here is a comment from the jacuzziui.py code:

    # Jacuzzi spas return a pump status of 0x02 when pump
    # 2 is On, which means the text returned by get_pump()
    # is "High". Since pump 2 has only 2 states (On or Off)
    # we use this local string array instead.

I'm impressed with how this is all evolving and fast. you guys rock. @jackbrown1993. I will make the 485 to wifi cable this week as I was still using prolink and will see how your code works with my encrypted board. I have a J-355, which should be very similar to yours, except for the encryption which makes me think there is some sadistic programmer at Balboa that enjoyed switching bits around.

I've been dormant the last 2 weeks and was still chasing the bit locations in relation to @dhmsjs unencrypted message findings. PIA to find the needle in the haystack amongst the 40 bytes. had made a simple script to colour the changed bytes on screen to help chase, but with your progress maybe it won't be needed. script here if it could be of interest. Not a programmer, so kudos to chatGPT entirely. https://github.com/pddc/jacuzzypy-compare

Hey @pddc, it's great seeing a few of us coming together and tinkering to try and build something great. If you want to branch off of my repo on what you are doing we can maybe create a script for development/testing which includes your color changing bytes?
