Fasades lighting script by time and outside sensor

[AlexLV]

Hi, I started to create widget for fasades lighting and easy script, but all not so easy for me. Idea - swich On/off by time or/and outside sensor.

At widget I need enter hour/min for On time and hour.min for Off time. Also I added Sensor control - Light level form sensor, Lux when Light will be On, and Delta when Light should be off.

Below my widget (not finished) and script. 

Some moments I need help:

1. How to show zero in front if hours or minutes from 0 to 9 ?
2. For me my idea not forking correctly, fasades light is flashing some times.
3. How check "mistakes" settings better?

Not found example at forum. 
i used resident script 1 minute.

Code:

HStart = grp.getvalue('0/1/100') -- Hours to start Fasades Light On MinStart = grp.getvalue('0/1/101') -- Minutes to start Fasades Light On HStop = grp.getvalue('0/1/102') -- Hours to stop Fasades Light On MinStop = grp.getvalue('0/1/103') -- Minutes to stop Fasades Light On SensorValue = grp.getvalue('1/0/100') -- Outside Light Sensor Value LUX SensorLightOn = grp.getvalue('0/1/105') -- LightOn Value LUX LightOffHysteresis = grp.getvalue('0/1/106') -- LightOff Hysteresis LUX ------------------------------------------------------------------------- now = os.date('*t') -- time table time = { day = wday, hour = now.hour, minute = now.min, second = now.sec, } if (now.hour == HStart) and (now.min == MinStart)then   FasadesLightTime = 1   grp.write ('0/2/19', 1) -- Group Fasades Light   end if (now.hour == HStop) and (now.min == MinStop) then   FasadesLightTime = 0   grp.write ('0/2/19', 0)   end if SensorValue <= SensorLightOn then SensorOn = 1   grp.write ('0/2/19', 1) end if SensorValue > SensorLightOn + LightOffHysteresis then SensorOn = 0   grp.write ('0/2/19', 0) end
