MODBUS Holding registers are not updated about core HOT 9 CLOSED

Hey there @janiversen, mind taking a look at this issue as it has been labeled with an integration (modbus) you are listed as a code owner for? Thanks!

According to the yaml you are not reading holding_registers.

Please run the debug with only the failing hub, otherwise it is very difficult to see if there is a bug or not.

Сan you tell me how to enable the debug only for the second one without disabling the first hub.
Thanks!

According to the yaml you are not reading holding_registers.

I have commented "input_type: holding" just for testing purposes only.
Initially input_type: holding was included into sensor config, but I decided to check the default settings ( input_type: holding) as noted in modbus integration documentation.
I read the holding registers (function 03) starting at address 40000 with offset 501 ( or 500 for HA).

Reading data from the weather station through third-party modbus utility.

Log with 1 hub only.
home-assistant_modbus_USR-W610.log

Sensors in HA. Temperature and humidity data are real.
Meteo_pool_wind has scan_interval: 5 sec
Meteo_outdoor_humid and temperature - scan_interval: 60 sec.
But no updates at all...

Your configuration seems to be wrong, you read address 500, count 8, but your next entity is defined at 504.

You could remove the custom an read float32 directly.

I cannot see any modbus errors, and as you can see the entities are read with scan_interval and the result is interpreted correctly.

If the data do not change the HA updater will not change the UI.

So in total I cannot see any modbus integration bug.

You're right!
My mistake. I specified the structure: ">4f" and the count: 8.
But I have to read 4 registers of 2 bytes each (int16) and correct is: count: 4 and structure: ">4h" .
Indeed there is no integration bug, everything is working correctly.
Thank you very much for your help on this matter!
