Need reliable electrical or mechanical 24hr timer

Click For Summary
SUMMARY

The discussion centers on the need for a reliable 24-hour timer capable of performing at least 50 cycles with a cumulative error of no more than ±30 minutes. Participants seek recommendations for components suitable for a home project that meets these specifications. The conversation also raises questions about the cumulative error period and the feasibility of using standard clocks for this application.

PREREQUISITES
  • Understanding of electrical and mechanical timer mechanisms
  • Familiarity with cumulative error calculations in timing devices
  • Basic knowledge of home automation projects

It needs to perform at least 50 cycles with a cumulative error of no more than [+\-] 30 minutes. This is for a home project.

Any suggestions of components?

I'm not sure I understand...why can't you use a clock (either electrical or mechanical)?
