For some battery-powered devices it may take up to 24 hours until the battery percentage remaining is send by the device. For some devices, this can be forced by removing the batteries for a couple of seconds and inserting the batteries back into the device.
As this is a Tuya device, it is not always guaranteed that HE inbuilt drivers will work with all models and manufacturers. If the battery reading (or the humiridy) does not show up within 24 hours, you can try this custom Tuya T/H driver.
