I have a solution that is working for the moment. I am using a script to call the relatively-new ‘reload config entry’ service, like this. It seems to be doing the job.
alias: System - reload Home Connect
description: ''
trigger:
- platform: time
at: '05:00:00'
- platform: time
at: '17:00:00'
condition: []
action:
- service: homeassistant.reload_config_entry
data: {}
target:
device_id:
- deviceid1 <- find this in the URL when looking at your Home Connect device page in HA
- deviceid2
mode: single
