Hi As the price of these gizmos goes up, the likelihood of them only going into something *necessary* also goes up. You simply can’t get the purchase approved otherwise. If you have to do a ship and return, you take that necessary chunk of the operation offline for (weeks / months?) while that process works its self out.
So - I wonder how well the device can project when it’s going to run out of Rb? A scheduled shutdown is always preferable to an unscheduled one.
