Describe the issue/bug

Since upgrading to 2023.08.23-0.5.5 from 2023.08.17-0.5.3 I get these messages in the logs now.

Can you try adjusting READ_ALLOW_GAP down to 1?

kellerza commented 1 year ago

You can also try updating to 0.5.6

dandare100 commented 1 year ago

Howzit. Thank you for the prompt response and for a lekker plugin.

Adjusting the READ_ALLOW_GAP to 1 did the trick. It is sorted now and running smoothly

kellerza commented 1 year ago

🚀 Glad it's working!

With 0.5.7 calculating the batch size should work even with a gap, but you only need to adjust this if you are having read issues/specific modbus gateways
