2.5.0

  • Added separate efficiency-mode thresholds for charging and discharging, so two batteries can share discharging early while charging stays on one battery until the surplus is large. Set MIN_EFFICIENT_CHARGE_POWER and/or MIN_EFFICIENT_DISCHARGE_POWER (#642, #755).

  • Added a minimum and maximum charge and discharge power per battery, so a battery stays idle instead of running at a few watts where it is least efficient, or is held below a limit you can change live. Set MIN_*_POWER / MAX_*_POWER and optionally MIN_POWER_HYSTERESIS, or per battery in Home Assistant (#721, #752).

  • Fixed the ESP32 build with MQTT Insights restarting itself while the MQTT broker kept dropping the connection; the meter now keeps answering the batteries through the drops (#748).

  • Fixed the Marstek app being told firmware version 148 for the emulated CT002/CT003 over MQTT; it now gets the same version a real one reports, 124 for CT002 and 122 for CT003 (#749).

  • Fixed the ESP32 build briefly ignoring the batteries every five minutes while cloud reporting was on, because each report held up the meter for a few seconds; it now reports in the background (#749).

  • Improved efficiency mode (MIN_EFFICIENT_POWER): when the running battery reaches its power limit or is full or empty, an idle battery now covers the rest instead of the house importing or exporting it. A 0 % Efficiency Window Weight now makes a battery a backup that covers what the others can't; to keep a battery out entirely, set its Distribution Weight to 0 or switch it inactive instead. (#751)

  • Added answers to the Marstek app's CT002 Diagnose on the ESP32 build: it passes while the board receives meter readings, and fails once they stop, instead of ending in a communication error. To report your real grid voltage and frequency, there and in cloud reporting, set voltage_sensor_l1–l3 and frequency_sensor under ct002: (#746).

  • Added Bluetooth to the ESP32 build, so the Marstek app adds the board like a real CT002/CT003, with no Marstek login, and shows its live grid power. Set bluetooth: false under ct002: on a board short of memory (#713).

  • Fixed cloud reporting showing twice the real grid power in the Marstek app's device list; reports now also carry the time slot, date and energy totals the way a real CT002/CT003 does, every five minutes. If you set a cloud reporting interval, remove it to use the real CT's 300 seconds (#744, #747).

  • Fixed the Marstek app and cloud reporting sending extra requests to a polled power meter, such as a Shelly or an HTTP source, on top of the batteries' own polls; they now reuse the batteries' latest reading (#698).
