Essent ICY Thermostat

[JuanUil]

Hi Folks,

I had a lot of problems finding the right way to control my Essent Thermostat.
Especially for putting it in a continuous temperature mode.
I have found a way of doing this by a Lua scipt.
Maybe it is old news for a lot of you but maybe some beginners (like me) find it helpfull.
I have made a dummy switch Constant temperature and one called home or away.
Further on I have made the heating program for workdays and weekend so now you can delete the programming in the thermostat.
Any questions don't hesitate to reply

Enjoy
Juan

Code: Select all

werkelijk= tonumber(otherdevices_svalues['Room Temperature'])

	werkweek = true; weekend = false
elseif (dag=='Sat' or dag=='Sun') then
	werkweek = false ; weekend = true 
end

-- Als we thuis zijn temperatuur instellen volgens een schema

Great script first of all. I have done it through a work around but get stuck a little.
I have created multiple virtual switches (which you can use in blocky too) to get more programmed Temperatures and times. The standard ICY is too limited.

On the Virtual Set Point, I have used the Timers function, which follows the same concept as your script.

The one thing that I want to do is to disable the Timers when I'm long gone. I have created a group of virtual switch for this too, but that goes by On and Off actions through JSON.
It's a bit tricky, but as soon as you read the JSON commands (Chrome browser) you can actually use them.
The one thing I wonder about, is the command I use now "sets" the timers each and every time, and switches them On or Off.

Code: Select all

http://192.168.200.6:8084/json.htm?type=command&param=updatesetpointtimer&idx=2&active=true&timertype=2&date=11/03/2015&hour=7&min=0&tvalue=18&days=256

Does anybody know if there are other commands for the &param=updatesetpointtimer? (idx is the idx of the timer, not the device)

If I leave anything out, the JSON return with an error. Just using &active=false would do the trick, but gives an error too.

The general idea is to have the Timers function do it's work, and have a Override button (Group) to switch each timer Off.

Cheers,

Ray

Nice script! I have one remark: I think you can better retrieve your temperature settings via uservariables.
So, in stead of:

Code: Select all

-- Temperatuur instellingen
dagtemperatuur = 20.5
nachttempteratuur = 15
vorstbeveiliging = 10

do:

Code: Select all

dagtemperatuur = uservariables["dagtemperatuur"]
nachttempteratuur = uservariables["nachttempteratuur"]
vorstbeveiliging = uservariables["vorstbeveiliging"]

You can then set those values in the Domoticz uservariables settings. This is much easier to update when you want to change it. Next to that, you can also update the variables with another script for example.
Same goes for the if statement with the hours:

Code: Select all

if (werkweek and uur==7 ...

You can better put this in uservariables, much easier .
