Set/Clear Bit in register. (without touching any other bits)

Set/Clear Bit in register without touching any other bits?

[davidrapan]

This would be another feature request. I see if I can do something about it. 😉

[davidrapan]

feat: Switch platform - bitwise operations:

      - name: Clear records
        platform: switch
        rule: 1
        registers: [0x0210, 0x020F]
        value:
          bit: 5

Edit: OR if the register has "auto-reset capability" or/and you want to use simple button ...

feat: Button platform - bitwise operations:

      - name: Clear records
        platform: button
        rule: 1
        registers: [0x0210, 0x020F]
        value:
          bit: 5

Edit2: feat: Add support for writing of values > 16b will be proly needed too.

Edit3: refactor: Moved bit prop in Button & Switch platforms is needed too.

Edit4: fix: Button & Switch platforms typo

Edit5: fix: Bidirectional writing across multiple registers

Edit6: fix: SolarmanWritableEntity - TypeError: 'int' object is not iterable

Edit7: refactor: Writing of 32b registers

Ah yes, you need to add:

code:
  write: 0x10

into entity description.

[davidrapan]

0x10 is normally the default but you have it proly changed at the group level?

[murik85]

Oh, yeah, I did that:

• group: Settings
  code:
  read: 0x03
  write: 0x10
  update_interval: 15
  items:

  • name: "BAT Type"
    platform: select
    rule: 1
    registers: [0x0BB8]
    lookup:

    • key: 0
      value: "No Battery"
    • key: 1
      value: "Lithium"
    • key: 2
      value: "Lead Acid"

  • name: "Meter Type"
    platform: select
    rule: 1
    registers: [0x00D3]
    lookup:

    • key: 0
      value: "No Meter"
    • key: 1
      value: "Current Transformer"

  • name: "EMS Mode"
    platform: select
    rule: 1
    registers: [0x09C4]
    lookup:

    • key: 0
      value: "SelfUse"
    • key: 1
      value: "ChrFst"
    • key: 2
      value: "SellFst"
    • key: 3
      value: "Maintain"
    • key: 4
      value: "CmdChr"

  • name: Restart
    platform: button
    rule: 1
    registers: [0x020F, 0x0210]
    value:
    bit: 3

It's all working. Thank you so much.

[davidrapan]

Wonderful! You're welcome! 😉

[davidrapan]

BUT...

Even it's working I think we have it implemented wrong. Writing now working with registers in this order [0x020F, 0x0210] but it should be [0x0210, 0x020F].

Cause if you set bit 3 which is number 8:

• Reading of [0x020F, 0x0210] using rule: 1 will result in 524288.
• Reading of [0x0210, 0x020F] using rule: 1 will result in 8.

So you will have to switch places of those registers in your custom yaml and I need to reverse order of writing those registers in the code.

[murik85]

Yeah, I noticed that too. But it was working just fine. Swapped it out, thanks.

Can you tell me if I should change the input registers too?

[davidrapan]

Can you tell me if I should change the input registers too?

Which registers?

[murik85]

code: 0x04

• name: "E PV"
  class: "energy"
  state_class: "total_increasing"
  uom: "kWh"
  scale: 0.1
  rule: 3
  registers: [0x0403, 0x0402]

[0x0403, 0x0402] or [0x0402, 0x0403] ?

[davidrapan]

No, I believe that those are correct:

• 0x0403 = low
• 0x0402 = high

And you would immediately notice if it was incorrect cause it would render insanely high production numbers.
