sensor.iphone_step is a string not an int

Hi,

In my experimentation with iOS application.
App version: 2025.5
“Steps” appears as a string instead of an integer so I can not graph or build automation based on value.

**Screenshots**

It seems a bug, It should be numeric (have a unit).

I found a workaround to add a graph-able value by adding in configuration.yaml

```yaml
template:
- sensor:
- name: ip14step
unique_id: ip14stepcalc
state: >
{{ '%d'|int(states('sensor.ip14p_steps')) }}
state_class: measurement
```

tks,
W.
