@penguin86 if there's any vibration on those wires (and they lead to a speaker) the stiff point of the system is the part of the wire with the solder infused on it. So that's the likely failure point.
I crimp jst-xh's for this, specifically that size because I have a big selection box of them assorted, and dont have dupont crimpers or ends.
Also very guilty of the crime of just pushing the wire through a pad and soldering it when space is tight, but this is prone to this failure too.

@worik pcb sits inline between Balboa hottub/spa controller and its topside panel which use a bespoke serial protocol to passing sensor data up + button presses down from the panel. Controller is older generation so no remote.
This extracts data for HA and injects button presses sent over mqtt/wifi giving remote capability. Which turns the spa into sink for excess solar generation as grid tied unpaid 3Kw max return. Currently reducing limits in opendtu's with HA dynamically to stay under limit.

And continuing on the Balboa #homeassistant project, built Magnus Per's interposer board using their github gerbers/schematics at https://github.com/MagnusPer/Balboa-GS510SZ, had pcb and parts prepared as needed it even if the pic read had worked. Tweaked the sketch to use static IP and flashed esp8266 with it. Now waiting for break in nasty weather to fit and test.

Epic fail. Need to get wife's spa connected to #homeassistant but gs500 balboa controller + topside combo isnt listed. Cunning plan, take old broken topside panel, hope read protection bit isnt on & dump its PIC16C62B chip and reverse for proto differences.
Hot air'd PIC onto SOP28->DIP28 pcb->socket on T48 minipro and it wont read, protection errors on vcc pin. Dont know if dead at start or heat death fatality in process. But its broke properly now. Have to make the sniffer board instead.

Another HA project. Kramer VS-120 AV switcher perfect for my retro console collection. 20->1 output -> scaler->hdmi switch->projector. I wanted a menu on #Homeassistant for people to select eg Atari 2600 and have everything configured to route audio and display. Kramer had rs232 mgment and win95 app. Sniff app inside kvm to get proto bytes. Then wrote code for esp32 to bridge network and kramer's serial & feed io to HA via mqtt. Can switch input from HA, and manual button changes to HA. Nice.

Hi Everyone I should probably write a hello post, since I've just been lurking.
Im pseudoing under jmp49 because I work in IT security although I'm GenX, and like to keep the worlds apart. Nobody needs to know everything in one easy to find place...
For fun I'm into retro hardware, software, canbus stuff, amateur radio etc. When I'm not in the office I do motorbikes and car & mechanical engineering stuff.

Tinkering in #inventree recently & wouldnt it be great if I could search it for the location of X using lab's #homeassistant page. HA>inventree integration broken (author aware), and too heavy for task. So wrote a HA script to search via latest api. Then someone said "I thought it'd be voice activated". Challenge accepted... Voice intents on HA and some yaml/scripts later We can ask HA voice pipeline "Where is a X" and it reads out stock location. Will try to make time to publish it on github.
