The smart IC card water meter shows that it is normal, and there are still 50 tons of water, but it just can't get out.

If there is water in the water meter, there is no water in the card. Without water, it cannot be said that the tool card can get water. It's the card, so it's possible. Even if you don't know if your home has less than 50 tons of water, if not, you can set the valve to 50 tons and then plug in the card to get water. This explains why your card can't be used, but the tool card can be used.
