DIYBMS v4

Hello everyone, there is also a new firmware with a Wifi fix.

One or the other has been affected by this, so try it out, it works well for me. No more reboots when the WLAN is off :slight_smile:

Issue:

Since overall power consumption is an important factor to you, you may want to consider these additional thoughts on the matter:

1 - the AP doesn’t have to be powered on all day; it only needs to be on whilst you’re using your phone to interrogate the battery (the battery will re-connect to the wifi when it comes back up, as will your phone).

2 - I haven’t don’t have any data to back up my claim, but I would imagine that if you’re only interrogating the battery from your phone for a short period a couple of times a day then the overall power consumption would actually be less than if the main controller supported AP mode and was broadcasting beacons all day long

Food for thought :slight_smile:

Thanks. My thoughts as well. Just need to switch on the AP when needed.
I’ve got a system working on an ESP 8266 (instead of an ESP 32) as this should use less power but I haven’t been able to test a 32 yet.

Back to that question, what functionalities are disabled when i dont use a shunt? Can i still use the dynamic charge/discharge function to control the Cerbos DVCC?

A long time ago i read here that you could not extend the lcd with a cable because of interference, well it actually works so if you need it you can do it.
