Connection Error - checksum error: Checksum error

[ochorocho]

Hey .. i've created a tiny homeassistant addon for the inetbox.py:

https://github.com/ochorocho/homeassistant-inetbox

This works so far. Data can be read and displayed in HomeAssistant. :-)

But i can't send data:

Cannot send updates to inetapp, no status received from CP Plus yet. Changes will be delayed until status received.

Any idea what is going wrong?
