script for controlling Essent (ICY) Thermostat

Posted: Sunday 08 November 2015 12:36
by JuanUil
Hi there,

I have made a script to controll my Essent Thermostat.
It controlls the temperature on time for weekdays and weekends.
But it also switches to nighttemperature after 1.5 hour as we are away.
and back to daytemperature when we come home between certain hours
The dummyswitch Thuis is controlled by pinging both mine and my wifes telephone.
You have to set your thermostat to vaste temperatuur, it then overrides the program of the thermostat itself.
Any comment is welcome!
Enjoy...

Script look great but are you sure it works?
I mean, the script when i use it isn't setting the new setpoint if needed.
Amended a little bit and now it does set a new setpoint when needed.

Just a little tip, some more information/details on what to change or create for users who don't have the knowledge would be handy.
Had to look how you wrote it and what i needed to create.

Compare my amended script to yours...

Yes script is working fine with me at home.
But I admid I could have and should have pointed out where users have to put their own data in.
Thnx for adjusting the script.

Sorry for my ignorance but i made a dummy 'Vaste Temperatuur' and have a correct working dummy 'IemandThuis'.
Is the dummy 'Vaste Temperatuur' or 'Thermostaat Dummy Switch' needed for the script to work? I dont see an IDX of this dummy in the script.. ?

Can someone explain the exact dummy's connected to this script, and how they are called?

Ive marked my uncertainties.. Sorry i'm new to lua..

Code: Select all

   
       setpoint = tonumber(otherdevices_svalues['E-thermostaat'])
    werkelijk = tonumber(otherdevices_svalues['Kamer Temperatuur'])
   
       commandArray ['Vaste Temperatuur']= 'Off'                                   No IDX?
 
       commandArray ['Vaste Temperatuur']= 'On'
Update: The script seems to work fine to 20C and when away to 15C! What does the dummy 'Vaste Temperatuur' or 'Thermostaat Dummy Switch' do?

An error occurs: 2016-03-09 11:02:00.453 Error: EventSystem: in script_device_Thermostaat.lua: [string " -- ~/domoticz/scripts/lua/script_device_Ther..."]:62: attempt to index global 'devicechanged' (a nil value)

Hi There,

the dummy switch vaste temp is ment to prevent the thermostat to go to nighttemp when he sees no movement for 2 hours

Hello, anyone, is there a Json command to set ''vaste temperatuur'' on a icy thermostat? I am not handy with Lua yet and would just like to enforce this setting in some cases.
Thanks in advance.

I think everything you need is in here: https://www.domoticz.com/wiki/Domoticz_API/JSON_URL%27s.

Something like json.htm?type=command&param=udevice&idx=<idx>&nvalue=0&svalue=<temperatuur>?

Hello,

I have implemented this script and it seems to work, however i'm wondering something: The value 'setpoint' that is read from and written to the thermostat idx. This idx in my case is the hardware device type 'icy thermostat' i created in hardware setiings and this polls from the icy-e online server using login/password. However, ICY has announced that this service will stop (or continue as a paid service) on 1-2-2019. Am I missing something here or will this mean the script will stop functioning then as the value cannot be polled anymore?

Ah, thank you Jos. That is unfortunate, as you pointed out there is no known way of connecting to the thermostat locally at this point. Maybe we should ask ICY..
