Need a timer app

I’m looking for way to control a dry or wet type zwave relay such as a Linear FS20Z-1 relay. The relay will drive a mister to spray mosquitoes etc. for 30 sec to 90 sec (I want to control). It needs to come on at sunset (with a ± minute variance) the repeat at intervals during the night. Can someone recommend how I can do this?

WebCoRE is one option you can look at…

Does anyone have code or something I can modify? If I described the functionality I need is there someone that could create this app?
