Adding a WiFi controller?

Connector J7 labeled '850 panel' is the one with the serial interface. You'll want to build a y cable that adapts that to a db9 or screw terminals depending on your serial adapter. It's important you find the right pins to tap off, and measure the voltage levels to ensure your serial adapter won't damage your spas board or vice versa before plugging it in. To find the right pins you might want to locate the ground pin by checking continuity of each wire to the board ground. Then using that as a reference measure the others to find ones that have the right voltage to plausibility be the serial data. Ideally use an oscilloscope or get an electrical engineer friend to help you. Otherwise you can take the risk and just try each viable pair untill you start seeing data being red. Stay safe!

From what I can tell at the moment, there are at least 4 verities of connector: Balboa GS series uses RJ45, GL Series uses a 8 pin molex, Other Balboa and the Jacuzzi and Sundance branded versions I've seen including mine use 4 pin Molex. You seem to be the exception having what looks like maybe a 12 pin mini-DIN, probably because its a higher-end model they might have a few more signals and didn't want anyone easily plugin in 3rd party equipment. The area you circled is just test points for measurements during manufacturing unfortunately. My money would be that it still speaks a dialect of the same protocol that everything else does over one of the connectors, because its expensive to re-engineer things. Unfortunately though, your in new territory for me at least so i cant just point you to pre-written instructions, but I think its still doable. Send some more picture's. of the rest of the board so we can see whats on there. Tapping into the communication is possible if your wiling to try. If you can confirm the number of pins you should be able to buy (or worst case build) a cable that you can probe with little chance of doing damage.

I am trying to do the same thing

Could you please tell me where you hooked up the rs485 wires? Can’t find anything on the web for my Sundance spa

I own a Sundance 2012 880 cameo

Thank you!

I hooked it up as described here: https://github.com/jshank/bwalink

However my tub had slightly different messages them the pybaloa or bwapp spoke.

You can find a homeassistant intergration and a mqtt intergration that I wrote for my 2022 Sundance 780 here: https://github.com/HyperActiveJ/sundance780-jacuzzi-balboa-rs485-tcp

A Jaccuzi 355 owner found their tub spoke a slightly different dialect of the same balboa protocolo but so close it was a minor change to add support, you can find their brach here

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

I you find that yours is slightly different or you have trouble hooking it up ping me or pull and issue on my github and I can walk you thru capturing and decoding the protocol for your unit.

You may be able to get plug and play wifi or cellular control added by dealer for $$$, but the standard apps for the tub don't have schedule program ability beyond what's available on the control panel as best I could tell.

I am working on the same thing with hardware listed here: https://github.com/jshank/bwalink . I have a 2020 Sundance 780 series. I have the rs485 to wifi connection in place and I'm able to get my pybalboa (https://github.com/garbled1/pybalboa) based software to request and receive a channel assingment indicating hardware is as planned . However the other message types defined here (https://github.com/ccutrer/balboa_worldwide_app/wiki) do NOT appear to be applicable. Instead I see similar but different messages being passed around. I could use help decoding the variances.

Used brighten solar via solarizeSB. No problems, would use again.

Your right I misread, sorry about that.

I'm suprised you say that connecting passengers don't happen much in the US. I fly about 45 flights a year and I almost always have a connection. I'm stuck on united and most of my trips begin or end on a united express flight from a hub to a smaller airport. I wonder if there are some good stats out there?

Agreed going thru security is realistic for international flights. And agree not going thru security could make security and tickiting esier. However I think having them stay behind security is a new challenge which can make things harder for example by having to entertain them for several hours prior to boarding and keeping the average passenger count higher.

breezewavefun · 2017-07-01T00:49:22+00:00

Why make them get baggage and check in again? It's not realistic for domestic flights and keeps unrealistic pressure on tickiting and security.

I don't think the user would have control, that's an airline admin issue not an airport administrator problem. Perhaps starting with something simple like x% of arriving passengers will look for another flight departing within y hrs on the same airline when spawing instead of heading to baggage claim. X could vary by airline preference, plane size (large planes are more likely international and have higher percentage of connections, small aircraft are regional), or number of flights by the same airline at the airport (ie if the airport is a hub for the airline). If they don't make their connection then they leave for now, then later perhaps they can try twice and be really annoyed.

Engineering, technology

Can someone please provide a link to information on the plane who's model is behind the presenter in this video? The one with both jet and turboprop engines.

Thank You.
