Initial value for global float variable not working #6004

Open KlausHans opened 3 months ago

KlausHans commented 3 months ago

The problem

I have a global float variable i want to initialize with 0 and restore it:

globals:
  - id: g_water_daily
    type: float
    restore_value: true
    initial_value: "0.0"

On boot, i set the restored value to a template sensor:

esphome:
  ...
  on_boot:
    then:
      - sensor.template.publish:  # restore today
          id: today
          state: !lambda 'return id(g_water_daily);'  
sensor:
  - platform: template
    name: "Heute"
    id: today
    icon: "mdi:water-plus"
    unit_of_measurement: "L"
    device_class: "water"

This doesn't work. The template sensor is always unknown after startup: grafik

I also have a global int-variable that restores pulse counts, it works flawlessly. That's why i think the problem is the float type. Also worth mentioning is, that the reset to 0.0 via globals.set works too.

try "Factory Reset Button"

KlausHans commented 3 months ago

Thank you for the suggestion, nice idea.

It didn't changed anything, but in the log there was an error while resetting:

Is this a clue where the problem is?

uli-rpi commented 3 months ago

Yes I had the same problem, and using factory reset button fixed it. Please refer to the "note" in the documentation

KlausHans commented 3 months ago

I did the factory reset at least two times. As i said, it didn't changed anything regarding the problem i posted. The template sensor, that should be initialized by the global float variable, that should be initialized with 0, is still unknown (int variable init still works). grafik

I don't understand your hint to the note. There is nothing of importance in there for me, it only warns for lost data and wifi connection.

ssieb commented 3 months ago

If you factory reset, it can't save the preference at reboot because you've deleted it. You can ignore that error. Watch the serial logs from boot to see what's happening with the template sensor.

uli-rpi commented 3 months ago

Sorry I was imprecise, I only did the factory reset once manually, after that the problem was solved for me

What exactly do you mean with serial log? I've added a restart button and this is the log via the esphome ui:

Is that the right log? I don't see anything helpful. Or do you mean to connect via usb and check with a serial connection/terminal?

yes

KlausHans commented 2 months ago

Hm, i don't know why, but it works now as expected. As far as i am aware i didn't changed anything in the yaml. Strange. grafik

KlausHans commented 2 months ago

Eh, i was to fast. After reset of the device the value is not restored. grafik Will try usb serial if i have the time for it.
