Show uptime as readable text

[bharvey88]

Version: 26.9.29.1

What does this implement/fix?

Replaces the numeric Uptime sensor with ESPHome's built-in uptime text sensor, so Home Assistant shows uptime as 3d 4h 12m instead of a raw count of seconds. Thanks to @kernelpanic85 for the idea in ApolloAutomation/R_PRO-1#72.

• Uptime is now a text entity. Its history graph and long-term statistics stop, and any automation or template that treats uptime as a number needs updating.
• Home Assistant sees it as a new entity. The old numeric Uptime entity will show as unavailable and can be deleted.
• The ID stays sys_uptime, so component.update: sys_uptime in the report scripts still works.
• At the 60s update interval ESPHome leaves seconds off, so uptime under a minute reads 0m. Battery devices that sleep right after reporting will usually show 0m.

Walkthrough

The ESPHome configuration updates the firmware version from 26.8.27.1 to 26.9.29.1. It removes the uptime sensor and adds an uptime text sensor with a 60-second update interval and a space separator.

Changes

ESPHome uptime reporting

Layer / File(s)	Summary

Priority: ⬇️ Low

Estimated code review effort: 2 (Simple) | ~5 minutes

Change: Feature

Suggested reviewers: bunton33

Merge Risk: ⚪ Minimal · up to 3d93b

Uptime will appear as readable text instead of numeric seconds, so automations and history or statistics relying on the former numeric entity may need adjustment. The update call remains supported, and no actionable merge risk is established.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 3d93b

The uptime change is an intentional breaking change for numeric consumers. The reviewed configuration does not show a new access or secret-handling risk, but deployment and rollback behavior remain unverified.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

• inferred — The demonstrated change affects the device’s reported uptime and its Home Assistant consumers. The available evidence does not quantify deployed devices or establish a wider authority change.

Trust Boundaries and Controls

• inferred — No attacker-controlled input, new credential or authorization transition, or privileged sink is established by the reviewed changed ranges; this does not verify the security of the broader deployment path.
