100Balance2MQTT

Little Program for ESP82XX to get the 100Balance and new Daly (H/K/M/S series) BMS data to web and MQTT

⚠️ This firmware requires a license for full functionality. The license is valid for the lifetime of the BMS used. If you set up the Wemos and cable yourself, you can purchase the license at https://all-solutions.store/license (when purchasing the PCBs in the store, it is automatically included).

Features:

• captive portal for wifi and MQTT config
• config in webinterface
• switching MOS gates over webinterface, MQTT and via web at /set?loadstate, set SOC over MQTT
• 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!!!)
• wake the BMS over MQTT or keep it awake (not supported on ESP-01s)
• universal switching output (only with external power supply, not supported on ESP-01s)
• blink codes for the current state of the ESP (not supported on ESP-01s)
