I deleted state.json and restarted the bridge.

Any code modifications possible to prevent crashing on wrong data type ?

I think you might be on an older version of the server. Could you please update to latest version and let me know if you are still seeing the error?

Hi,

I just updated my version, we will see

For my other issue on the SmartThings forum, I will open another issue right away

Thanks
