Success

I am happy to report that changing the configuration "time" to

time:
  - platform: homeassistant
    id: homeassistant_time

resulted in the totals resetting at midnight as they were supposed to.
Thank you mgulick !

hmm...
for me, that results in:
*** [/data/emporiavue2_1/.pioenvs/emporiavue2_1/src/esphome/components/sntp/sntp_component.o] Source src/esphome/components/sntp/sntp_component.cpp' not found, needed by target /data/emporiavue2_1/.pioenvs/emporiavue2_1/src/esphome/components/sntp/sntp_component.o'.
