Description
While trying to write a script to reduce the charge current of my electric car charger (called amina, connected via Zigbee2MQTT) by changing the number.amina_charge_limit value, I can see it in the graph but it does not actually happen. In the image below you can see in blue that the script changes the values (around 10:35) but the actual current (yellow) stays the same. Later, just after 10:38 in the graph, I changed the number.amina_charge_limit in the HA GUI, and then the actual current, with a small delay, does change, as expected.
It looks like state.set does not work as expected. I am expecting the charger to reduce current and the value in the graph to change, but only the value in the graph does change. The new value is somehow not communicated to the underlying device (zigbee2mqtt in this case). I checked also the zigbee2mqtt logs and values of the charge_limit do not change when running the pyscript, but do change when changing it in the GUI.
My test script:
@service
def test_state_set():
state.set("number.amina_charge_limit", value=13)
log.warning(f"1: {number.amina_charge_limit=}, {sensor.amina_current=}")
task.sleep(10)
state.set("number.amina_charge_limit", value=10)
log.warning(f"2: {number.amina_charge_limit=}, {sensor.amina_current=}")
task.sleep(10)
state.set("number.amina_charge_limit", value=13)
log.warning(f"3: {number.amina_charge_limit=}, {sensor.amina_current=}")
task.sleep(10)
number.amina_charge_limit=9
log.warning(f"4: {number.amina_charge_limit=}, {sensor.amina_current=}")
task.sleep(10)
number.amina_charge_limit=6
log.warning(f"5: {number.amina_charge_limit=}, {sensor.amina_current=}")
task.sleep(10)
number.amina_charge_limit=13
log.warning(f"6: {number.amina_charge_limit=}, {sensor.amina_current=}")
log file result:
