“The old lady”  works on technical problems, too. Fresh batteries and an alternate setting. Alas, “the old thermometer”  hasn’t responded to my resuscitation efforts. (1) New batteries, (2) swapped to a second sensor, (3) worked with settings, (4) pictures of my futile efforts! ~~ “Other activities“: Washed the dishes, washed my hair, took a shower, and prepared Hummingbird nectar.
