Getting unknown for next watering sensor

[mash2k3]

Describe the bug I get unknown state for the sensors next watering and delay finished

Expected behaviour get a timestamp for both sensors

BHyve devices HT25 Wifi hub gen 1

I downloaded bhyve_next_watering.py and moved it to \config\python_scripts

Added python_script: to config.yaml

called service service: python_script.bhyve_next_watering data: entity_id: switch.frontyard_zone

It created the 2 sensors but the states are unknown
