Unable to keep @state_triggers running.

[code-in-progress]

So, I've started using pyscript recently and one thing that always seems to get me is that my @state_trigger functions get called once and then they basically never respond again. I've had success with @mqtt_trigger functions (which I might just use instead), but I'd like to be able to get @state_trigger working properly.

My setup: HA core-2021.2.3 and pyscript 1.3.1 (HACS install).

This is a simple script that I wrote that should trigger off a group of 2 motion sensors:

`
@state_trigger("group.kitchen_motion_sensors == 'on'")
def kitchen_lights(**kwargs):
task.unique("kitchen_lights")
log.info(f"Triggered; turning on the kitchen lights with {kwargs}")

mode = None
timer = 180

if binary_sensor.mode_manager_early_morning == 'on':
    mode = "early_morning"
    timer = 180
elif binary_sensor.mode_manager_morning == 'on':
    mode = "morning"
    timer = 300
elif binary_sensor.mode_manager_afternoon == 'on':
    mode = "afternoon"
    timer = 300
elif binary_sensor.mode_manager_evening == 'on':
    mode = "evening"
    timer = 300
elif binary_sensor.mode_manager_night == 'on':
    mode = "night"
    timer = 90
elif binary_sensor.mode_manager_overnight == 'on':
    mode = "overnight"
    timer = 30

scene.turn_on(entity_id=f"scene.kitchen_{mode}")
log.info(f"Timer for kitchen lights set at {timer}.")
task.sleep(timer)
scene.turn_on(entity_id="scene.kitchen_off")
log.info(f"Cleared; turning off the kitchen lights")`

If I'm understanding correctly, group.kitchen_motion_sensors is a valid state trigger target as it exposes 'on' or 'off'. However, I have the same issue when it comes to using binary_sensor.kitchen_motion_sensor_1.

Any ideas?

I ran the following test repeatedly with success. I imported your function, changing only the trigger variable to match one of mine:
@state_trigger("input_boolean.sunshading_active == 'on'")
def kitchen_lights(**kwargs):
task.unique("kitchen_lights")
log.info(f"Triggered; turning on the kitchen lights with {kwargs}")

On my Lovelace control panel I toggled input_boolean.sunshading_active, which triggered the function and created log messages repeatedly. Note that with the " == 'on'" test, it will only trigger when changing state from 'off' to 'on', not the reverse.

I HAVE had a situation that seemed similar to what you describe, but upon investigation of the log file I discovered the trigger had invoked code that had terminated with an error, causing Pyscript to stop running.
