Zanzito Device Info Configuration Help

Im trying to get the extra device info from Zanzito into HA for a few automations. I have Zanzito setup now working fine, it provides me the location and battery level at the moment.

I seen a post about getting more info like charging and that using topic zanzito//device_info

Ive added this to a mqtt sensor and when i look at the logs I see it is sending the information but looks like it is hitting a 255 charector limit and/or having trouble with the time format. Has anyone else ran into this?

Sensor:
  - platform: mqtt
    state_topic: "zanzito/my_cell/device_info"
    name: 'S9 Status'

Logs:
da@hass:/home/homeassistant/.homeassistant$ cat home-assistant.log

Also, if there is anyway to get heart rate data too that would be nice :slightly_smiling_face:

This does indeed appear to be a 255 character limit. I raised a bug.
