Need a little help here with a few things;
-
I run an odd sized bank. I have 17S2P that I wish to monitor. How do I best do this? I currently have 17 modules hooked up and running, 0/0-1/0 and thats working just fine, sorta. How do I add my other 17S bank? Do I need to run a second loop with its own controller and IP address?
-
How can I can the volatge RANGE on the maiin screen? I run LiFePO4 and my MAX is 3.65vdc, so I would like the max voltage say 3.75vdc. The reason is that screen is not well used all being at the bottom. Is there some code that I can edit, or is this hard coded? and option on the settings screen would be nice.

I am getting some errors, and I am not sure why, it works mostly, hangs up sometimes. I can Leave a window open to the settings page in the background so I have access to the reset button, and that works most times. When I say hang up, I mean that the busy circle in the middle just keeps rotating and never fully loads.
on my modules page I see many bad packets on some but not all modules heres a clip;

Notice that the mass of errors around cell 0/9. What is the likely cause of this?
-
Also, could you add a rule that uses the temp Int? This would be nice in addition to cell temp. Ie turn on a fan for high temp, or disable charging for cold cells etc.
-
Do the wires between the modules need to be twisted? If so how many twists per inch/cm?
-
Self powered controller? It there a possibility of including a small voltage reg to buck the pack voltage down to 5v? The other advantage is a controller based voltage sense.
Thats all I have for now.
PS Stuart, I have exposed my esp via a port forward so you can poke around if need be, PM me for the link so you can see the errors I am getting. Due to no security on the webpage I won’t post this publicly.
Thanks in advance, Michael.
