[CB2S] Issue with power readings about libretiny HOT 11 CLOSED

more precise: inverted signal on CF and CF1

from libretiny.

p24 = pin 16 on the BK7231N qfn32 which is virtually mapped to arduino D3 in libretuya.

from libretiny.

also p6 and p7 are not D0 and D1

from libretiny.

There's no pin 34, so I believe this is a typo.

@descipher If you take a look at the docs here, you can see that D0 and D1 are indeed P6 and P7.

Since yesterday, you can actually use the P* pins directly in esphome config (make sure you have the latest commits for both esphome and LibreTuya).

Sorry guys, i don't understand, is there an error in my config? Or this type of power meter is not supported?

Thanks

from libretiny.

This type of meter currently has some sort of problem. We're investigating it, and hopefully we'll find a solution in the coming days.

ok @kuba2k2 thanks for the fast response, i could help of course, please give me some hints to where to look to fix

from libretiny.

You can try adding a basic pulse_counter component, and see if it reports anything:

sensor:
  - platform: pulse_counter
    pin:
      number: D0
      mode: input
    name: "D0 Pulse Counter"
    update_interval: 10s
  - platform: pulse_counter
    pin:
      number: D1
      mode: input
    name: "D1 Pulse Counter"
    update_interval: 10s

(adjust the pin numbers as needed)

from libretiny.

Tried with your suggests but i receive 0 pulses/min in the two pins, so i think the problem might be in pulse_counter also

from libretiny.

Thanks to the help of @catalin2402 i successfully read the current/voltage/power from that BL0937
I will post the updated yaml soon, the trick was to invert cf and cf1 pin

from libretiny.

Like promised this is the yaml

sensor:
  - platform: hlw8012
    model: BL0937  # note that the model must be specified to use special calculation parameters
    voltage_divider: 780  # adjust it according to the actual resistor values on board
    current_resistor: 0.00107
    update_interval: 10s
    sel_pin:
      number: P24
      inverted: true  # the logic of BL0937 is opposite from HLW8012
    cf_pin:
      number: P7
      inverted: true
      mode:
        input: true
        pulldown: true
    cf1_pin:
      number: P6
      inverted: true
      mode:
        input: true
        pulldown: true  
    current:
      name: 'Plug 1 Current'
    voltage:
      name: 'Plug 1 Voltage'
    power:
      name: 'Plug 1 Power'
    energy:
      name: 'Plug 1 Energy'
      # convert it to kWh
      filters:
        - multiply: 0.001
      unit_of_measurement: 'kWh'
      accuracy_decimals: 4
