I have been using BigTimer node to turn on a floodlight at 4:45AM every morning, and off at sunrise. It's been working fine for many months, maybe more than a year. It's disabled in the node during the summer months and was supposed to resume in September.
However, ever since September 1, it's been turning on the light at midnight.
Here is the flow. Any ideas why bigtimer is turning on the light at midnight??
