  1. I am thinking about the board to put everything on... Leaning towards white opaque 5mm correx boards, which is great to print on (dials etc) and the flows leds can shine/glow through and be nicely diffused without too much extra work. Will need get a sample board to test that theory 1st. And on the back can maybe add some foam board for sound dampening. The servos should/could then be isolated from the front correx so sound/vibration should be a lot less as the front board will/should have less chance of amplifying the vibrations.
  2. Just finished coding the mqtt, now to start with the servos to use most of that data
  3. Un-Check Solar Export then it will be the same as mine which has been working great for almost 3 years now Do not check Limit to Load Only unless you do not want your non-essentials powered. Yes if there is load-shedding the batteries will still charge if there is enough power for the loads and any left over will go into the batteries. Is there a particular reason you Have the inverter limited to 500W ?
  4. It should not make too much difference either way. Also I have some other ideas that will use up some more of those pins It is more just a personal preference to use a single string which I can segment in software. My coding is DIY/hobby level so I learn as I go if it becomes too dirty I will certainly try splitting the string and seeing if it makes the coding easier or harder. It's the only one I found that gives me the functionality I need for this use case. Yes, it has a ton of effects. Will start looking at options/styles for the dial faces and needles on the weekend. Not really given thought to the indicator led's yet either. Again, thank you for the inspiration to give this a good try
  5. I am close, just need to do a test print to make sure I got the scale correct. There are 8 Flow segments, one battery level segment and one matrix segment. Total LED's 105 in the segments and 256 Led's in the matrix. With the coding so far it ended up being better/easier to split the segments from the matrix, so ended up using two data pins. The 9 Servos will use I2C Wifi will call mqtt to populate the display data. Overall the esp32 is going to be doing some actual work for a change
  6. I am using mqtt so I can get the data from any of my existing sensors without need to re-code anything, idea is so that anyone can make some small tweaks and then have their data populate the display. Many people use HA so they will/should be able to use their data easily. ( THAT'S THE THEORY ANYWAY ) Will see how that goes with the programming I had a spare 5m roll of 300 led 60/m WS2812B in a drawer gathering dust, i am putting that to good use now for the flows Programing it is a bit of a bitch, as I am using 1 single string segmented to 13 pixels per segment or whatever size is needed at each location Took all afternoon to get the scale worked out, now I just need to use the scale and do all the rest of the flows. All the segments will be cascaded together into a single string. Using fastled patterns and palettes make the programing reasonably slick. Here you can see 2 segments of 13 pixels each working nicely independently from each other. Colours and directions change nicely according to the data received from mqtt WhatsApp Video 2023-12-27 at 6.27.44 PM.mp4
  7. I am going to give this a go I am waiting for my BMS PCB's from China so quite bored... My initial mockup using 100cm X 70 cm footprint. esp32, 9x mini SG90 180d servos driven by pca9685 16 channel and using ws2812b led's for the flows and battery SOC For a change all the parts were available locally at decent prices, should get delivery on Friday and bonus is the servos were on promotion at botshop for 2x 5 pack (R260)
  8. @HedgeSlammer Maybe try ws2812b led's, then you do not need all those shift registers only single data pin needed. And if you set the intensity to low/mid range then the esp8266/esp32 will easily handle up to 300 of those led's before needing any power injection.
  9. Definitely not correct You can add new batteries to old, you can add bigger batteries (AH) you can mix and match as you like as long as the chemistry and cell numbers match.
  10. And for SA you could add nice LED's to indicate load-shedding status too Currently my back kitchen rgb smart light changes colour depending on loadshedding status, but this would look so much cooler.
  11. I tried getting my wife to use all my graphs, she said the data is just too much for her. This, I believe, she will appreciate and use for sure.
  12. This is the freaking most awesome project I have seen in ages... Well Done... Love it!
  13. I had a look at your projects on github a few weeks ago
  14. Yes I know about that, it's the one Andy promotes and did some tests on. He called it the "Peter" board Very neat project and using esp32 makes it open to many possibilities, that is until they decided to close the source code behind a paywall. I will have to just plod along tinkering away with the opensource code that's available.
  15. I am doing this purely out of curiosity to find out what all the fuss is about battery/inverter comms. My batteries have been running just fine for a few years now using voltage settings and the JKBMS. That said, I am quite intrigued at how everything works now that the JKBMS is controlling the inverter and it seems to be doing a pretty good job This project is very very simple and can currently only handle 1 JKBMS to inverter. The LCD display is optional for those who like to see visually at a glance whats happening. I personally like the LCD as it is way easier to read than the inverters screen This is a passive device (install and forget ) that just sits between the BMS and the inverter, allowing the BMS to instruct/suggest the inverter what to do. You still do all the usual settings on the JKBMS itself. Once I am satisfied this basic one works well, then I will have a go at porting it to an ESP32 so we add more functionality like settings, charge algo's etc just like the one Andy has been promoting.
  16. I am going to drink now, you got my 3dimensional brain in a total twist now
  17. Agreed, unfortunately standardisation forces/pushes prices downwards, the big industry players do not like that. they draw better than me but you get the idea.
  18. I would love the new JKinverterbms but I already have 4 of the older ones and they work perfectly
  19. Orientation is correct for the connectors. the wires will not crossover. So if e.g. you buy two female leads you would simply solder the same colour wires together. OR You can solder one lead directly to the board side. Reason I did it this way: not everyone will have the ability to make up the cables, so they can simply buy 2 female cables and solder the same colour wires together
  20. You should get the new JKInverterBMS it has ALL the bells and whistles Quoted Directly from Andy's website
  21. @Kalahari Meerkat Let me know I have used your suggestions and redesigned the board with a decent voltage regulator to accommodate the VBAT from the JKBMS. Turns out VBAT is the full main battery voltage. I have made it so you can choose (jumper) if you want use/solder on RJ45 or micro JST for the JKBMS side. The cable for using the Micro JST option is straight through female-female so no confusing getting it right And you can choose if you want to use VBAT from the BMS or external 12v Supply. Let me know what you think
  22. Lol no worries ... .I thought you meant you found a place in Cpt meaning you lived in Cpt I am sure someone will assist you, or as @Scorp007 mentioned go to battery place they usually kind enough to assist, I used to do that before I bought my crimper.
  23. @Greglsh I do all my own cables so you are welcome to message me and let me know your location in CPT, if you are not too far away will gladly visit and help you do the crimps
