Daly2MQTT GitHub release Discord

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
  • 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)

Collection of docs, software and firmware around Daly BMS. Firmware-Updates are at your own risk! NO SUPPORT!

Completely assembled and tested PCB's

You are welcome to get fully stocked and tested PCB's. These are then already loaded with the lastest firmware. The earnings from the PCBs are used for the further development of existing and new projects.
