2 years ago Hi! I use the ethernet connection. You should follow this link https://www.photovoltaikforum.com/thread/150898-byd-hvs-firmware-update/?postID=2215343#post2215343 (it's German but I am sure you will use a translator) User Becker3 has a very good documentation how to reach the battery via ethernet.
Hi, I am looking around for some tooling to read my HVM with ModBus. Unfortunately I could not yet find any docs about that but I found your project on photovoltaikforum.
Before going into further details I would like to ask, how you connect to the battery. You state that you use the WiFi of the battery. But that should turn off after x minutes. Is there any way to use the ethernet connection? What do you do to stay connected?
Best Ben
