Using pyscript functions instead of template sensors?

[vvuk]

Howdy! Is it possible to use pyscript to build entirely new entities, similar to how template sensors/entities work? The built-in templating engine is... less than optimal. I believe I can already do almost all the needed bits with pyscript -- I can define triggers, and within that trigger function I can set state values. But I need a new synthetic entity to set state on; any suggestions on how I can create that?

I just saw #129 -- it looks like what I'm looking for. But is it required, or is there a less-elegant workaround possible before this is merged?

Okay, answering my own question. state.persist works perfectly well for this use case. Sample in case someone else comes looking for this:

POWER_ATTR = { "unit_of_measurement": "kW", "device_class": "power" }

state.persist('pyscript.tesla_card_grid_to_house', default_value="0", default_attributes=POWER_ATTR)

@state_trigger('sensor.powerwall_load_now', ...)
def recalc_power():
    ...
    pyscript.tesla_card_grid_to_house = 123.0

so, I guess when you use auto_entities (hacs), you can automactly add this to lovelace (when you create the names in a smart way :) )
