homebridge-miot: Roborock s7 maxV Ultra does not report values

Describe the bug A clear and concise description of what the bug is. I have a Roborock s7 maxV Ultra vacuum, and configured this plugin. The HomeKit accessory does not report correct “battery”, “mode” and “dock” values. All always remain at 0 or not detected.

Expected behavior A clear and concise description of what you expected to happen. When vacuum is in its dock, fully recharged, it should report 100% and docked to yes. When adding a monitored property on the “mode”, the lux sensor should report something other than 0.

Your config.json Provide the config.json entry for your device.
