Modpoll v1.6.0 gives warnings: | pymodbus.logging | BinaryPayloadDecoder is deprecated and will be removed in v3.9.0 !

[andrehmj]

After an upgrade of my Pi from Debian 11 to Debian 12 (Bookworm), the old version of modpoll (installed in 2023) stopped working, so I installed the latest version v1.6.0 (with pipx, because "pip3 install modpoll" gave the error "error: externally-managed-environment". )

However, when using this v1.6.0 I get lots of warnings like this one when reading data via modbustcp:

2026-01-01 13:47:41,394 | W | pymodbus.logging | BinaryPayloadDecoder is deprecated and will be removed in v3.9.0 !
Please use "client.convert_from_registers()" or "client.convert_to_registers"
See documentation: "https://pymodbus.readthedocs.io/en/latest/source/client.html#pymodbus.client.mixin.ModbusClientMixin.convert_from_registers"

It seams like an incompatibility with pymodbus v3.9.0, however when reading 189b3fd I think that modpoll v1.6.0 should already be compatible with pymodbus v3.9.0?

Who knows what's wrong? Any help is appreciated!
