Connected but no reading

Recently purchase of this tyre pressure and I had installed it and it showed connected but it doesn’t show and reading as show on the pic

Probably the batteries are empty. Best check by changing the battery on one of the sensors, and see if data shows up then.

Thanks.

You are right. I had changed the battery and it works

You might want to contact Nonda customer service to get reimbursed for the empty batteries they delivered with the product.
