Accessory stops working after a certain period of time
Not sure how long it takes, but somewhere a bit over a week, the accessory stops working. It still shows as responding in the Home interface, but when trying to turn the TV on or off, it fails.

Restarting Homebridge temporarily fixes the issue. Soft workaround is making a cronjob to restart homebridge once a week.

I'll try and get logs next time it happens.
