Hello! You recently added a Multicooker to support chunmi.cooker.eh1. But I have such a multicooker writes that it is chunmi.pre_cooker.eh1. Please add support.

Name of the device: Xiaomi СhunMi IH Rice Cooker 5L

Model: chunmi.pre_cooker.eh1 Hardware version: esp32 Firmware version: 2.0.7_0018

I tried to connect the rice cooker through the repository sschirr/xiaomi_cooker

There was an error in the file xiaomi_cooker/custom_components/xiaomi_miio_cooker/sensor.py in line 71, I replaced the construction locally
