I'm having errors on 61, 62, 63, 64.

Only writing, reading works good as always

Well it seems like your device does not support function code 6 (preset single register). Unfortunately Modbus is very often not thoroughly implemented. I have seen a couple of devices that do not support function code 16 (write multiple registers) when writing only one register. Since that seemed to be common I changed spiciermodbus2mqtt to always use function 6 when writing only one register: 687b9a9

A device that only supports function code 16 that is a new quirk. I will add a a command line option to exclude specific function codes.

Wow,

Indeed modbus implementations are a mess.

I roll back temporarily to version 0.65 and it's working.

Thanks so much for the debug, and for the project, is being working very well.

Please use the command line option --avoid-fc6
