Existing modbus integration of a Smartmeter stopped working as expected after HA update to 2025.6.1

After HA update to 2025.6.1 the value of my smartmeter starts now to appear as “unavailable”

here how it is looks like before update:

and here how it looks like after the update, note the interruptions

during that interrutptions the values are “not available”

here is the configuration, any idea how to fix?


      
modbus:

        unit_of_measurement: kWh
        state_class: total_increasing
        device_class: energy
        scan_interval: 600

per default, the scan interval for power demand is 10 seconds, Ive tried everything, now 2 seconds, but the value stills gets unavailable.
