Re: Python Plugin: Smart Virtual Thermostat
Hy Guys,
This week I finally where able to install this plugin and its working great, thanks logread and all other contributers!
After reading the posts I read the option to install multiple instances of this plugin. Because I'm not that guru and want to create multizone heating I'm looking for some pointers how I can do this.
Do I simply copy the plugin into an extra directory "SVT2" and then proceed as I did with the first one?
Hopefully somebody is willing to help.
Thanks again, Johnny

In the domoticz hardware page you can just add a second one with a different name.

Re: Python Plugin: Smart Virtual Thermostat
You can add the SVT hardware multiple times. Only the thermal characteristics will be shared and that is not optimal, since every room can have it's own thermal characteristics.

Re: Python Plugin: Smart Virtual Thermostat
Quoting myself: an idea: what about giving the uservariable with the settings the same name as chosen when the hardware was created? By doing so, every thermostat can build it's own set of parameters for optimal functioning in that room. (in our case, floor heating downstairs and convectors upstairs. Totally opposite from eachother)jake wrote:You can add the SVT hardware multiple times.

Re: Python Plugin: Smart Virtual Thermostat
To which variables are you referring? I have 4 different SVT's set up for four rooms. They each have their own internal variables in the user variables. Each containing the following string (with different values of course):jake wrote: ↑Saturday 24 November 2018 21:33Quoting myself: an idea: what about giving the uservariable with the settings the same name as chosen when the hardware was created?

To test it, I created a new 'test thermostat' and to my surpris it creates a new uservariable with the name [name-of-thermostat-as-given-in-hardware-page]-InternalVariables
Yes, the plugin already has the flexibility to create an own set of unique parameters for each room.
Thanks for correcting my statement.

Re: Python Plugin: Smart Virtual Thermostat
Yes, multiple instances of the plugin work well for a 'zoned' heating solution. You just need one (or more) temperature sensors for each area and also a heater switch for each area.
I use z-wave TRVs on each radiator to regulate the heating appropriately in each 'zone' and have virtual 'Call for heat' switches (see below) that are triggered by the different temperature sensors based on the settings of virtual thermostats.
The need for 'Call for heat' switches
If you only have one boiler switch then you need the virtual switches to call for heat otherwise if you just use the real boiler switch in the SVT hardware parameters the different instances of the plugin will conflict with each other trying to switch the heat on and off.

Re: Python Plugin: Smart Virtual Thermostat
Hi,
Yes it is true, if you use SVT on central heating with TRV and one boiler, need to make some "adjustments", as script and/or virtual switches etc.
After month of test of the LC13 (and popp version that is same), and speaking with Danfoss etc. What we are sure.
First, temperature measured by the TRV is not each time as the one measured by the room temp sensor. Most depending of the position of the TRV, angle etc. More is the is curtain near it...etc. The result is if you have TRV and SVT for same zone, the risk is asking 21 for example in SVT, and if ask same at the TRV, never reaching this set temp.
So. When you have several zone etc, you need to use the TRVs as more or less ON/OFF control of the radiator.
For this, when heating is requested, ask setpoint of 28 to the TRV, when OFF, ask 17.
IT is what we do in several installation for testing, it work well...
As i wrote, i am working on SVT plugin for trying to make one version of it for central heating with TRV. About this, &logread, your help can be very good. And better if we can make only one working with all. But i think will ask for hours of coding and test...
And for now, all mode parameters are used..
What is needed.
First, adding in the SVT one dummy named for example "Heating request", and that will turn off or on depending if SVT ask for heating.
Like this can be used for controlling the central boiler (or heat pump) using a small script if you ahve several SVT in same system (but i am working also on one plugin for controlling the boiler with several "heating request" switch and using the water temp control depending of the outdoor temp, meteo etc).
For now what i have tried :
my work is here : https://github.com/Erwanweb/SVT3/blob/master/plugin.py
After :
if 7 not in Devices:
Domoticz.Device(Name="Heating Request", Unit=7, TypeName="Switch", Image=9, Used=1).Create()
devicecreated.append(deviceparam(7, 0, "")) # default is Off
i tried :
# flip on / off as needed
self.heat = switch
command = "On" if switch else "Off"
Domoticz.Debug("Heating '{}'".format(command))
for idx in self.Heaters:
if switches[idx] != switch: # check if action needed
DomoticzAPI("type=command¶m=switchlight&idx={}&switchcmd={}".format(idx, command))
if switch:
Domoticz.Debug("End Heat time = " + str(self.endheat))
Devices[7].Update(nValue=0, sValue="100")
else:
Devices[7].Update(nValue=0, sValue="0")
I try to do this but have some bad returns for changing the state.
Some one have one idea ?

Re: Python Plugin: Smart Virtual Thermostat
I control the TRVs so that when the boiler first switches on they are all set at 28 degrees, after that, when the room temperature sensor is above the target the TRV is instructed to 'turn down' by twice the difference between the target and the room temperature, equally this is also the case if the room is below the target then the TRV is 'turned up' by twice the difference.
This allows for a more gradual transition between the radiator being on or off and seems to assist in maintaining a steady temperature.
I also adjust the set-points based on the outside temperature and time of day and additionally increase them if it is raining or the wind gust is high (to counter the cooling effect of drafts (we like to keep the window vents open for fresh air.

Re: Python Plugin: Smart Virtual Thermostat
@jake, @alanlsmith,
Many thanks for sharing your experiences and how you have been tweaking your setups around the SVT plugin... @alanlsmith, your tip for "Call for heat" virtual switch is great.
@Erwanweb,
I am not sure it is useful to add another switch to the plugin, considering the solution provided by @alanlsmith... Most users probably will want fewer default devices, not more !
Feel free to fork for your own needs though, but by the way your code for switching a switch device on/off is wrong... nValue = 1 or 0 is to be used... not sValue

Could you clarify your algorith?
Lets say you want 23 and the current temp is 20. I guess you set 28 on TRV. When the temperature reaches 23, you do nothing as the difference is 0. Everytime the temperature changes, you adjust TRV setting ? When it gets to 23.1 you turn it down by 0.2 and set it to 27.8 ? When you got 24 in the room, you set 26 on TRV? In such cacase valve would probalby be still full openened, so the temperature in room will keep rising, wouldn't ?
I have exactly same cause as you and would like to use your experience to set up my heating
Regards
Piotr

Re: Python Plugin: Smart Virtual Thermostat
You are almost right Piotr, what I failed to mention is the frequency with which the room temperature is checked. So what actually happens is that, with a target of 23° and a TRV fully open at 28° if the target is exceeded by 0.1° then the TRV is turned down by 0.2°. Then 2 minutes later this is checked again and if the target is still exceeded by the same 0.1°the TRV will turn down by another 0.2°(obviously if the temperature has continued to rise, as is likely, e it will turn down by more) until it is effectively turned off.)
The adjustments to the TRVs are limited to between 17° and 28°
Also, as the room temperature has exceeded the target the thermostat in that room would have turned off the 'call for heat' switch. This may turn the boiler if no other rooms need heating but if it doesn't the 2 minute monitoring of the TRVs will continue to adjust them to attempt to maintain the temperature near to the target.
Originally I had a plus 0.1° and minus 0.2° tolerance around the target that was constantly recalculated and if those limits were exceeded then the TRV would be adjusted by 5 times the difference but this seemed overly complicated.
A bit long winded I'm afraid but I hope it is understandable.

Re: Python Plugin: Smart Virtual Thermostat
I'd say when room temperature is below setpoint, increase valve setpoint to 28 degrees, the other way around: lower it to 17 degrees.
In other words, when the boiler switch is on, TRV setpoint to 28, otherwise to 17 degrees.

Re: Python Plugin: Smart Virtual Thermostat
Here is the script I use to control the TRVs, there are comments explaining most of the sections.Skippiemanz wrote: ↑Friday 07 December 2018 23:10 Alan, Sounds nice! do you do this with another script or?
I'm looking for the same kind of setup
There are 4 rooms Front, Kitchen, Bedroom and mumsroom.
The script requires 4 temperature sensors (I actually use 2 in each room and average them to provide the temperature for that room), 4 virtual thermostats, 4 TRVs, 1 boiler switch, 8 variables holding the max / min temperatures for each room and 4 virtual text devices to show a summary for each room, the last section of the script deals with the generation of data for these sensors.
There are 2 boost switches one for the whole house and one just for the bedroom, these increase the SVT set point to 1.5° above the current temperature for 1 hour.
There is also a round function that is used to make sure that the target and actual temperatures are in the same format for comparison. this function in my script is called from a separate script, it's pretty standard but I have included the function below for reference.
Code: Select all
--Round to a set number of decimal places
function M.round(what, precision)
if (what) then
return math.floor(what*math.pow(10,precision)+0.5) / math.pow(10,precision)
else
return math.floor(val+0.5)
end

Re: Python Plugin: Smart Virtual Thermostat
Welcome everybody,
Great job with SVT, thanks anyone involved. I inteend to use it with my Synology. I do have a problem, as such termostat runno problem, I can not change the setpoint temperature by event. Other events like swich on/off work no problem, but setpoint temp not, may you have any advise?
Edit: I,ve soled it this way, time must be set to > or < as event need time to be trigered
