dzVents script for heating control

Post by Eoreh » Sunday 14 January 2018 17:16

Me and my friend Tom would like to introduce our dzVents script to control the heating in our homes.

Main goal is switch on/off device depending on the temperature in a user-friendly interface
The script requires the following objects in the domoticz:
- 1 x device to switch on / off (Central heating boiler)
- 2 x thermometers (Main and backup)
- 3 x selectors (Heating - working days with buttons for zone of hours exp: [5-22] or [5.30-22.30] or [5.30-7/14.00-22]
Heating - weekends with buttons for zone of hours exp: [5-22] or [5.30-22.30] or [5.30-7/14.00-22]
Working mode with buttons [AUTO],[MANUAL],[HOLIDAYS],[OFF]
- 4 x setpoints (Comfort temperature,Economic temperature,Temperature for manual mode,Temperature HOLIDAYS)
- 1 x text device (Current working status)
- 2 x user variables type:string (HeatStatement, HeatWorkCondition)

the script has rich debug logging. For example as below

Mode of action:
AUTO:
System checks the temperature, time and day of the week every 2 minutes and it compares the data it receives to all the selectors like “Heating- working days”, " Heating - weekends" and setpoints “Comfort temperature”, “Economic temperature” etc. Then it sets itself to either comfortable or reduced temperature.

MANUAL:
The system takes the temperature from „Temperature for manual mode” (Temperature for manual mode) as the comparative value and according to that it controls the heating in a way it keeps the same temperature all the time- any of the day time modes don’t matter at that point. At 11PM the mode changes to AUTO on it’s own.

HOLIDAYS
The system takes the temperature from „Temperature HOLIDAYS” [Temperature for the time when nobody is home for a longer time] as the comparative value and according to that it controls the heating in a way it keeps the same temperature all the time- any of the day time modes don’t matter at that point.

OFF:
The system does not control the temperatures or anything else.

Current system operation status:
Is displayed live in Domoticz, in “text” type of switch.
Let me add that in my living room there’s a tablet on the wall running ImperiHome, displaying all the switches that I explained earlier and it’s really easy to control all the settings from it.

Selectors
Hours are taken from the names of the buttons to operate the script. The hours must be separated by the "-" sign. There may be zones on the button separated by the '/' sign. All hours can contain minutes with separator '.'
Hide Off level in selectors is on TRUE.

Notifications
Notifications are sent on a pushover in default only NOTIFY_TIME = 'at 05:00-22:00'
You can easily change this in code.

Code: Select all

Nice. On tip for better readability (shorter lines) is to rename domoticz with dz.

Thank You.
By the way it would be great if the object "domoticz" to contain more information about information about environment. Especially the "port" on which the web server is running, then it would be possible to set up the objects in script when it doesn't exits.

Owh.. that's interesting. It is actually there but not documented. I made sure it is in 2.4.0. For now you can do:

Code: Select all

domoticz.settings['Domoticz url']
In 2.4 you can do this:

Code: Select all

domoticz.settings.url
domoticz.settings.serverPort
domoticz.settings.webRoot
Right now you can get the port:

Code: Select all

local port = globalvariables['domoticz_listening_port']

Hello

I'm just discovering Domoticz scripting, and now the dzVent part... Very interesting !

I just managed to get a heating control script in Lua working, except my timers do not work for some reasons (OnTime planning configured on virtual switch), I'm still pulling my hair off and suspect this is a bug...?
But I'm also looking at dzVent option as well now...

So thanks for sharing your version.
Btw, I guess you made a small typo in the "function(domoticz,device,triggerInfo)", you probably have an "s" missing for "device"
=> function(domoticz,devices,triggerInfo) ?

Cheers
Olivier

No, that's not a typo. That parameter is the device that triggered the script.

Yes, it is an alternative in a way. But - in my opinion - our solution is more flexible and user friendly.

I love this script as it can be configured from dzVents.

Anyone using this script for the Anna thermostat? Got the first setup working but need to redesign a bit so the Anna thermostat temperature is altered when the script result decides to start the heating.

If I read this correctly, you're controlling the boiler temperature off the thermostat in your living room, with an alternative thermostat used only in case the 1st thermostat fails to deliver a temperature, right?

Have you thought of putting (z-wave) controlled thermostats (f.e. Eurotronic Spirit or fibaro's FIB_FGT-001) on the various convectors in your rooms, to achieve zone-heating? that way you would have a thermostat plus valve in every room, making it possible to set a preferred temperature for each room separately (for example, I like my bathroom to be warm in the morning, but it doesn't need to be heated the rest of the day). The main script would need to control the boiler temperature based on the demand from all of the rooms. I'm thinking of making this a next project of mine and am seeking for other person's ideas.

Yes it works only as backup. 1st.

This script dont support multi-zone heating. It will be hard to achieve in its architecture (but of course you can try to adapt it to your needs)

You have to create virtual sensor type "Text" with name "Current working status CO", for proper operation of the script

Are you variables set as STRING?
Looks like you made your variables as INTEGER, which is not correct

Just an example, don't look to the name of the variable.
But the variable type needs to be STRING, not INTEGER

Hi
Thanks for last reply, I have literally just seen it.
I appear to have only 1 user variable called HeatStatement that is now String.

I have rectified other issues and finally down to this now

Sorry with this i can't help, i don't have that much knowledge of scripting

It looks like it gets no value for "num"
The function round makes a decimal whitout ','
when it gets a number 4,3, than the function makes it to number 4 (the 0,3 are cut off).
I think the problem is not on line 84 which your error says, but somewhere else in your script. But where, that's the question.

Did you made the 2 variables?

"Round" function in which the error occurs is used in the line with devThermometer_second in line nr 295

Code: Select all

 temp_current = round(domoticz.devices(devThermometer_second).temperature,2)
I think problem is with proper set "secondary termometer" in line 16

Code: Select all

	local devThermometer_second = 'Backup thermometer'           -- backup thermometer to control switch  when main thermometer dont work  (lastUpdate > max_time_last_seen)
