Automation is executed multiple times
**Describe The Bug:**
I have an automation in Homekit that should turn off the heating in the children's room every evening at 7 pm. Unfortunately, this only works sporadically. Yesterday I saw in the Homebridge log that several commands are sent at the time of switching. Probably the order always varies a bit, that's why it works sometimes. With the Homebridge version 1.2.5 it works without problems. The log refers to version 1.3.0 beta 46.

**To Reproduce:**
1. create an automation in the Homekit app
2. wait until the automation time has come

**Expected behavior:**
Automation is executed only once.
