I also saw the firmware update notice, but I had hard time to update the firmware. I tried the update a few times and always failed at the point where “installing firmware” appeared. Then I heard a couple clicks inside the faucet and the LED went off. After that the BlueTooth connecting screen appeared and stuck there until timeout. The “something went wrong” showed up. I powered cycle the faucet and it reconnected back to the hub. Firmware did not update to 41, stil at 0041.
Don’t know the difference between these 2 firmware. I will stay at 0041 as it works for 2 years.
