Water box level is always at 0%  (Roborock T7 / roborock.vacuum.a11)
I got a Roborock T7 (roborock.vacuum.a11)
Everything is working fine except the water box level is always at 0% in homebridge and home app
But the log in the homebridge is: 
`INF getWaterSpeed | roborock.vacuum.a11 | WaterBoxMode is 202 over miIO. Converting to HomeKit`

Is this normal? or is there anything I can do to make it right?
Thank you so much 👍
