Subject: Request for Firmware with Heater Control Support Hello Daly Support Team, I'm currently using your BMS and noticed that the DO output, which should enable heater control as per your documentation, isn't functioning as expected. The "Heater" option seems to be either missing or disabled in the app with the firmware I have installed. I'm looking for a firmware version that supports this heater control feature via the DO output. Additionally, if there's a compatible upgrade tool and instructions for flashing the new firmware, that would be great. Also, can you clarify if there's an official Daly heating module designed for this BMS, or may I use the DO output to control a standard heating pad through a relay or MOSFET? Your assistance is really appreciated!
