Write 32bit register.

[murik85]

Is it possible to write a value to a 32-bit register?

[davidrapan]

Of course, what you are trying to accomplish?

[davidrapan]

Are you sure that what you have is a proper documentation for your device? What brand and model you have and which yaml profile are you using currently?

Did you check that the value (currently 15) does match value of the configuration item on your device? (To confirm that you are trying to change correct parameters)

[murik85]

Yes, the documentation is correct. The register is 100% read-write. The register is written through Node-Red without problems (I switch stick logger to “transparent” mode).

[davidrapan]

So in the device it's currently set to 15W?

[murik85]

Yes

[davidrapan]

Your issue is not about 16b or 32b or if the register is writable or not. Stick is simply refusing to accept the value you are trying to set it to and I have really not much idea why... 😕
