Sensor Rain delay errors on startup

See original GitHub issue

The following appears in my home-assistant log upon every restart for the rain_delay_*_remaining and rain_delay_*_finishing for each device:

Those rain_delay_finishing and rain_delay_remaining sensor examples are a bit… fragile. They were indicative only.

However - I do have a python_script which creates and updates sensors to do this which I’ll package up into a release. Will need a day or two to publish a beta release.

@TheGardenMonkey I’m going to close this issue as the original startup errors have been fixed. I am aware of the limitation of the next watering script ignoring non-smart watering programs 😃
