Accessory Simulation (1 Lock w/ single-channel)
* **Please explain your feature request in a one or two sentences.**
When adding accessory simulations, accessory list must be refreshed.


* **Is your feature request related to a problem? Please describe.**
Adding a simulation to an existing device, makes that device double on HomeKit.

I figured out as follow:
1. Add a simulation to an existing device;
2. Disable the Ewelink plugin; (all Ewelink devices will be removed)
3. Enable the Ewelink plugin; (all Ewelink devices will be available, and those with simulation now well displayed in HomeKit).


* **Any particular eWeLink devices that this relates to?**
This simulation: 1 Lock (w/ single or multi-channel device)


* **Anything else?**
Siri can't manage the "unlocked" status with this simulation: "1 Lock (w/ single or multi-channel device)".
Siri says: "Can't open the gate" despite the gate has been unlocked correctly.
Using the iOS Home App, this simulation works perfectly.

I hope this helps you.

Thanks for your job.
