daly2mqtt's Introduction

Daly2MQTT

Little Program for ESP82XX to get the Daly BMS data to web and MQTT

Features:

captive portal for wifi and MQTT config
config in webinterface

get essential data over webinterface, get all data like cell voltage and more over MQTT
classic MQTT datapoints or Json string over MQTT
get Json over web at /livejson?
firmware update over webinterface
debug log on Wemos USB (use only if you don't supply Wemos from BMS!!!)
