Sorry, I missed that. Why isn’t it just a header? I mean that’s a lot of real estate and you force the user to mount the controller where it can be seen. Why not an LCD attached via cable?
I’d like to hear a real user. I can speculate what they might be thinking as well as anyone.
The guy that makes the electrodacus bms says that people wanted the LCD for “security” reasons. I’ll bet that bogus reason is driving some of these requests.
The cost of adding a 2nd user interface to the DIYBMS is enormous. The time to program it, the questions that come from it, the requests for more and more features, and especially if they start demanding horrid little buttons to make a rotten UI that can change the settings… just shoot @stuart. He’s already helping individuals sort out wiring and programming problems. A second UI doubles his troubles.
The cost of buying some used phone, or tablet, plugging a usb cable into it and mounting it where you’d mount the LCD strikes me as a better solution because I would not be limited in placement except by my ability to get power to it. And all of this is so that I don’t have to switch to AP mode to see the status?
Sorry, but the LCD seems like a very poor choice for @stuart. It seems like a recipe for a ton of work.
