Doorbell 2 connected to the Chime Pro with the weakest signal

I have 2 chime pros. The 1st chime pro typically provides the doorbell with an RSSI of -60 to -58. The 2nd chime pro's signal is around -70 to -65 due to more walls between it and the doorbell. With both chime pros on-line the doorbell is almost always connected to the 2nd one with the weaker signal. Does anyone know if the doorbell periodically looks for a better chime pro signal and connects to it? It doesn't seem to be doing that in this case. As a test, to see if there is a problem with the 1st chime pro, I can unplug the 2nd chime pro then the doorbell works great with the 1st chime pro with the stronger signal.
