Did you recognize that _sendAttemptsLeft is never resetted on an successful call of SendOutputValuesAsync in

• BuwizzDevice
• Buwizz2Device

I know it's not perfect there, also PoweredUp devices had similar issues in past. In general there are more sever issues right now, unfortunately. My fix policy is to address the most important issues and smaller ones I hope there will be chance to let them fixed in the originally repo, it it comes to live again.

Teoretically neither BuWizz3 is correct as _sendAttemptsLeft can be set in the meantime.
I tired to reset it conditionally here: https://github.com/imurvai/brickcontroller2/pull/127/files
