Schedule a trend sensor to start sampling at specific time?

Configuration
1

My thermostat starts heating at 6am, but sometimes the furnace doesn’t turn on. I have a trend sensor setup for the temperature to alert me when the temp is not rising but I get many false positives. I’d like to schedule the trend sensor to start sampling at 6am so it is in sync with the thermostat. Is this possible?

Two possible solutions:

  1. incorporate time conditions into your notification automations to prevent the false alerts.

  2. Set a really long Scan interval for your sensor (years). Then use an automation with a time pattern trigger and a time window condition to call the update_entity service to update your sensor regularly from 6am to whenever.

perhaps you need to configure your sensor so it gives you less false positives?
you can still impose time limits but the main issue is false positives and imho it’s better to get rid of them than limit their number :wink:
