core: iTach remote device not starting correctly

Home Assistant release with the issue:

0.80.3

Last working Home Assistant release (if known): 0.78.x

Operating environment (Hass.io/Docker/Windows/etc.):

HassOS, raspi 3b Component/platform:

https://www.home-assistant.io/components/remote.itach/

Description of problem:

When restarting HA more often than not, one or more remote devices defined for the iTach component will not work (will not send IR command). The device that fails is random. A restart of HA may correct the issue (all devices work as expected) or a different defined device may stop working. Other devices defined for the iTach component do operate as expected so it is not the component failing as a whole.

This is a problem with the HA component as I can still send a command directly to the non functioning device using putty to communicate directly with the iTach unit.

I note that quite a bit of ‘tidy up’ work was done on this component about the time the issue appeared. I have removed the redundant “device:” requirement but this made no difference.
