I’m currently in the process of designing and building a battery balancer and monitoring system/circuits for a home made DIY Powerwall. I’m aiming to use this forum to log the design decisions and gather comments and improvements from the wider community. This is some useful background reading fro…

i did that and they contacted me to ask for more money (Hi, the panel is no more than 100*100mm and it needs you to pay for extra board fee 6.1$ . If the extra fee haven’t been paid ,the order will be cancelled for you in 2 days.Thanks!)

I made and ordered this panel in the end (happy to supply gerbers) [Untitled_Combined_Top] as I had similar issues.

thanks but they already started production on the controller so all i need is the smaller one

Wouh, good to see! I am still debugging. My AttinyModule double blinks every 8 seconds. The ESPController blinks every 4 seconds. But I still don’t recieve any data. In my case it’s my first SMD-soldering. So I try some more soldering and debugging :wink: I love this project! Great thanks to Stuart…

Hello all. Thanks for all your time and energy into this project. I am having an issue with v3. Modules disappear when I try to provision a second module. First module is fine. My understanding is to leave the first one connected, then connect the second one to the first one and provision again. Wh…

Ok, I’ve got the hardware dialed in. After a couple of bricked attinys and a some 710’s replaced, I’ve finally got the cell modules good. I can’t see any modules on the web interface. I’ve flashed my Amica Node MCU controller with the correct settings (again), and went through the wifi setup. The c…

Fred, are you referring to the V3 boards? If so, did you follow the provision process?

Yes, V3 boards and I believe so. I’ll give a brief history of my process maybe someone can figure out what went wrong/not done correctly. I assembled 6 boards (I only need 4 currently). The only issue was that the 710’s had no pin 1 markings so I toasted a couple before I figured that out. I progr…

No luck. I’ve reset both the controller and the module to ‘factory’. Then, using Arduino 1.8.5, successfully loaded both scripts (including the bootloader on the mod; bootloader first). Successfully provisioned but nothing on the Management console. Ok, this is what I see without cell module conne…

I finally think I’ve got it. I needed to be sure that there is 3.3V to the NTC thermistor, and I needed to be sure that the ADUM’s pins were ALL soldered down. It really helps a lot :smile: THANK YOU to all that put in the time and energy needed for this project’s success, I am grateful! [finally…
