room monitor 276 reports good battery status and 0C/32F/0%RH when batteries are low

I installed five 276RM sensors with my upgraded smart hub, 3-in-1 outdoor sensor, and one T/RH tower.  The performance has been OK except for recurring short periods of poor communication with the hub (random as to which sensor, sensor location and reported signal strength; data are lost for 1-2 hours).  But overnight one 276RM units switched from reporting actual room T/RH to 0%RH and 0C/32F temperature even though the battery status continued to report as normal.  After six hours of bad T/RH signals I checked the batteries and found each was reading 0.9V so clearly depleted.  The sensor returned to normal operation after replacing the batteries.   

What is the point of reporting "battery status" that is wrong, especially if the sensor does not report a low battery even after the point where the readings are erroneous because of low voltage?  I guess I am pleased that the radio continued to work at such a low voltage.

Hello Bruce,

I have reached out to our development team to find an answer as to when the low battery alert will trigger on My AcuRite. It is possible that your batteries did not reach the threshold to trigger the low battery alert.  Once I have that information I will update you. Thank you.

Hello Bruce,

You should of gotten an alert. The low battery alert will trigger when it isaround 2.5V. Please put fresh batteries in and let us know if you experience this issue again.
