Energy sensor shows summation delivered multiplied by 100

Tongou TO-Q-SY1-JZT Zigbee Rail Switch Sensor shows “summation delivered” multiplied by 100 in Energy dashboard (i.e. 90 kWh instead of 0.9 kWh). Other readings (voltage or current) are displayed correctly.
Does anyone have an idea of a simple way to present the measurement correctly? How to divide by 100 and move the decimal separator? I have tried with the Riemann helper, but the result is not satisfactory. First of all, it produces kkWhh.

Template sensor, replace sensor.powr2_energy_total with your energy sensor

Thanks for the accurate hint. It works. I don’t know why I clung to the Riemann helper. Cheers!
