Moon phase

[Yihaaa]

Hereby my suggestion to add a "moon phase" feature.
On a lot a standard weather stations the phase of the moon can be seen and it looks me a good idea that it would be nice to have this implemented also in Domoticz

[soiltech]

*bump*

would love to see this as well, it is an important part for gardeners using this controller.

Please give more details

URL, screenshot, API, usage, .....

I believe he'd like the data from: http://www.wunderground.com/weather/api ... onomy&MR=1

more specifically:

moon_phase
percentIlluminated
ageOfMoon
phaseofMoon
hemisphere

If I'm not mistaken,

[gizmocuz]

So something like a moon rise/set ?
I still do not get its usage ? Why is this important ? And can't the sun set/rise be used ?

Not sure, but found this: http://www.almanac.com/content/planting ... g-calendar

Could be something in it

[alexsh1]

No need to add anything to Domoticz.
One has to use the existing capabilities to add things like moon rise/set in case needed.
Please see my lua script below. Do not forget to add 5 dummy sensors and name the script "script_time_moon.lua" before placing it in lua directory under scripts in domoticz folder.

PS I am still developing it

forecast.io have this information in daily json

Code: Select all

daily: {
data: [
{
time: 1465941600,
summary: "Light rain throughout the day.",
icon: "rain",
sunriseTime: 1465963534,
sunsetTime: 1466020087,
moonPhase: 0.34,
precipIntensity: 0.0141,
precipIntensityMax: 0.0317,
precipIntensityMaxTime: 1466017200,...

moonPhase: 0.34,
just add it in forecast.io hardware like wind or rain?

moonPhase (only defined on daily data points): A number representing the fractional part of the lunation number of the given day: a value of 0 corresponds to a new moon, 0.25 to a first quarter moon, 0.5 to a full moon, and 0.75 to a last quarter moon. (The ranges in between these represent waxing crescent, waxing gibbous, waning gibbous, and waning crescent moons, respectively.)

[gizmocuz]

Why not calculate the moon-phase yourself ?

http://www.nano-reef.com/topic/217305-a ... e-arduino/

[jackslayter]

and add dummy device in Dz with moon phase like Alert device

[gizmocuz]

Why a dummy device? We could create a 'moon sensor' ?

[jackslayter]

yes, like Alert sensor

[Toulon7559]

For Python-applications the modules Astral and PyEphem provide easy & accurate calculation of moonphase, etc.

[gizmocuz]

I shown the calculation part already above... not that difficult, and should be easy to add to the system, just like the sunset/sunrise is calculated
Infact, someone could use that as a start place to implement it

Thanks @alexsh1!
I used your script and modified it somewhat

The result looks like this:

-- Original by: alexsh1 in https://www.domoticz.com/forum/viewtopic.php?f=31&t=107

Good work @ wizjos!
Is your moon icon changing according to the moon phase? Very nice - now I'd like to implement it too

"There is a lack of scientific evidence proving the beneficial effects of astrological gardening."

Nonetheless the moon phase is a nice extension to domoticz.

I'd love to, but I'm not completely sure about what exactly your question/problem is. When looking at your screenshot you're adding a uservariable. I use this variable to determine when the last check (= property lastupdated of this uservariable) was done. At this time plus 3600 seconds ore more the check/update is performed again. The uservariable displays a time, but this is purely cosmetic. The check is performed against the time of the last update.
Does that answer your question/clarifies things somewhat?

Nice icon..
