Our maintenance guy did the ladder round last month with the OTA-capable firmware. Yesterday we pushed 2.1.1 (the reconnect fix) to my office board first, then to the profile in waves of 5. All 30 show Updated, no ladder. One room went « No answer in time » because the board was unplugged by housekeeping, it updated the next morning when it came back. The first upload was refused because the Name was « Room-Sensor » with capitals and the boards report « room-sensor ».
