UPS Plus is a new generation of UPS power management module. It is an improved version of the original UPS prototype. It has been fixed the bug that UPS could not charge and automatically power off during work time. It can not only perform good battery power management, but also provide stable voltage output and RTC functions. At the same time,it support for FCP, AFC, SFCP fast charge protocol, support BC1.2 charging protocol, support battery terminal current/voltage monitoring and support two-way monitoring of charge and discharge. It can provide programmable PVD function. Power Voltage Detector (PVD) can be used to detect if batteries voltage is below or above configured voltage. Once this function has been enabled, it will monitoring your batteries voltage, and you can control whether or not shut down Raspberry Pi via simple bash script or python script. This function will protect your batteries from damage caused by excessive discharge. It can provide Adjustable data sampling Rate. This function allows you to adjust the data sampling rate so that you can get more detailed battery information and also it will consume some power. The data sampling information can communicate with the upper computer device through the I2C protocol. UPS Plus supports the OTA firmware upgrade function. Once there is a new firmware update, it is very convenient for you to upgrade firmware for UPS Plus. The firmware upgrade can be completed only by connecting to the Internet,and execute a python script. Support battery temperature monitoring and power-down memory function. UPS Plus can be set to automatically start the Raspberry Pi after the external power comes on. The programmable shutdown and forced restart function will provide you with a remote power-off restart management method. That means you don’t need to go Unplug the power cable or press the power button to cut off the power again. You can set the program to disconnect the power supply after a few seconds after the Raspberry Pi is shut down properly. And you can also reconnect the power supply after a forced power failure to achieve a remote power-off and restart operation. Once it was setting up, you don't need to press power button to boot up your device which is very suitable for smart home application scenarios.

Automatically turn on when there is an external power supply (If the automatic shutdown is set, when there is an external power supply, it will shut down and restart the board.)
1) If you want to completely shut down, please don't turn on the automatic startup when there is an external power supply.
2) If you want to shut down the UPS yourself because of low battery power, you can shut down the UPS first, and then automatically recover when the external power supply comes.
3) If you simply want to force restart the power, please use another method.
4) Set to 0 to cancel automatic startup.
5) If this automatic startup is not set, and the battery is exhausted and shut down, the system will resume work when the power is restored as much as possible, but it is not necessarily when the external power supply is plugged in.
bus.write_byte_data(DEVICE_ADDR, 25,1)

Restore factory settings (clear memory, clear learning parameters, can not clear the cumulative running time, used for after-sales purposes.)

Enter the OTA state (the user demo program should not have this thing, after setting, unplug the external power supply, unplug the battery, reinstall the battery, install the external power supply (optional), you can enter the OTA mode and upgrade the firmware.)
i have the impression that you do NOT have a EP-0136 UPS. the i2cdetect command for this device should show i2c responses for addresses 0x17, 0x40, 0x47 and 0x68, 0x68 being the real time clock.
your device only shows responses for 0x40 and 0x68, and there is a good chance that 0x68 is a real time clock and NOT an INA219 sensor which your code tries to address. there is a good chance that your UPS is some other model (EP-118 ??? check with the photos on the 52pi wiki).
make sure you got the UPS which ordered, and just keep the first part of the .py script which seems to be working.
