Unpack error while trying to write into register

[PaulOckenden]

Anyone know what this error means?

write_multiple_holding_registers. unpack requires a buffer of 132 bytes

(I’m trying to set one of the parameters used in TOU mode).

(And probably being an idiot!)

Thanks.

It could be due to many reasons:

1. Wrong function used
2. Used wrong register
3. Trying to set the register to incorrect value
4. Just bad luck (No kidding, I already heard from many people that it worked for them after they tried it for x time)

Thanks. I didn’t know whether the “132 bytes” thing would be a clue.
