Fix: Cannot read properties of undefined (reading 'setCharacteristic')

[Copilot]

Fixes a critical runtime error where the CookRefresh service was causing Cannot read properties of undefined (reading 'setCharacteristic') when HomeKit tried to initialize characteristics.

Root Cause

The error occurred because this.CookRefresh.Service was undefined when setCharacteristic was called. Unlike the Internal and Ambient temperature services, the CookRefresh service lacked proper fallback logic to create the service when getServiceById returned undefined.

Solution

Added service creation logic for CookRefresh that matches the pattern used by other services:

if (this.CookRefresh) {
  if (!this.CookRefresh.Service) {
    this.CookRefresh.Service = new this.hap.Service.Switch(this.CookRefresh.Name.toString(), this.CookRefresh.Name.toString())
    if (this.CookRefresh.Service) {
      this.CookRefresh.Service = this.accessory.addService(this.CookRefresh.Service)
      this.debugLog(`${accessory.displayName} Cook Refresh Service`)
    } else {
      this.errorLog(`${accessory.displayName} Cook Refresh Service -- Failed!`)
    }
  }
}

This ensures this.CookRefresh.Service is always defined before characteristics are set, preventing the undefined error.

Fixes #27
