Python Plugin: Smart Virtual Thermostat

[SzuR]

Ok thanks so i have to try till it works.
Are you using stable domoticz or beta?

Edit
So frozen domoticz was an issue with last domoticz update. Couple people have same issue and it is connected with mydomoticz allowed in settings...

This is a pretty impressive plugin.

You mentioned that the plugin required 2 to 3 days to learn. What's happen in case of restart of domoticz or even the hosts system. Are we back to 2 to 3 days of learning ?

The plugin saves the « learning » in a dedicated user variable that it creates. This survives a restart or a reboot (and is backed up as you make backups of domoticz). Only if you delete that user variable will learning be lost.

Interesting, I'll have a look. I was not aware that a uservariable could be created .

Thanks

You can't create it, but you can 'modify' it, if you know what you're dining. Worst case you simply delete the content and let the plugin recreate it.

Still having problems with Domoticz crashing.
Pity.
Just by reading about it it seems the easyest and best solution to create modulation on my 19 years old boiler.
Waiting for a version without bugs.

Anyway: Thanks for all efforts you have put and still put into it.
Great job @Logread!

PS
What is the most gracefull way of deleting Smart Virtual Thermostat from RPI.
I do it by deleting SVT directory and a restart.
I have the impression there is more to delete.

Do not use « localhost » as IP in the plugin configuration page... use 127.0.0.1

And yes your dummy temp sensor with idx 9 should be ok then

Following is not succesfull
- using 127.0.0.1 instead of localhost in hardware settings of SVT
- removing login info in hardware settings of SVT
- removing login of both domoticz and SVT

update:
error is probably because no devices are added bij Domoticz after adding a SVT hardware item

You are correct, domoticz does not create the devices if you so not allow it to: see the settings page and allow new devices to be created. This should resolve your issue.

This is a pretty impressive plugin.

You mentioned that the plugin required 2 to 3 days to learn. What's happen in case of restart of domoticz or even the hosts system. Are we back to 2 to 3 days of learning ?

Similar question: what happens if the target temperature changes over day? Does the learning persist?
Thanks.

[Logread]

Plugin version 0.4.4 is now available on GitHub.

This does not bring any new functionality but improves handling of some errors or incorrect configuration parameters, based on users feedback (always welcome...).

Install/upgrade instructions as usual on Domoticz wiki at https://www.domoticz.com/wiki/Plugins/S ... ostat.html

Similar question: what happens if the target temperature changes over day? Does the learning persist?
Thanks.

The target temperature has nothing to do with the learning. Just read the description on the plug-in page. The learning is all about the room characteristics and those are applicable for all temperatures.

"an advanced virtual thermostat based on time modulation and self learning of relevant room thermal characteristics (including insulation level) rather then more conventional hysteresis methods"

[elgarne]

You're right. Thanks.

[alfpresa]

@Logread Thank you very much for your work. I've installed it without issues and I've been able to connect it through a Remotec ZXT-120 to my AC with heat pump (which doesn't have an on/off switch, but I've been able to emulate it with a virtual switch and a simple blocky script). I was wondering if, as remotec has the chance to set the air temperature, if it could be posible to turn this into a smart virtual modulating thermostat instead of just an on/off one . May be it could be as easy as, instead of using an on/off switch, it could use optionally an level selector switch to control heat intensity.

Keep up the good work!!

[Logread]

@alfpresa, thanks for your appreciation. I am afraid your suggestion of proportional vs. binary (on/off) heating control will be difficult to implement: it would require a totally different logic than what the plugin is based on.

[alfpresa]

@Logread What a pity, but totally understandable. It's anyway an awesome plugin, so keep it up!

May I also ask you some advice about the plugin configuration for my use case (with an AC heating pump). I've the feeling that with my setup I might require an smaller calculation time span (may be 15 minutes?), as AC heating is pretty fast heating the air, but not that fast heating the structure itself, so the temperature varies in very short cycles. The problem is that I'm unsure of what the impact of smaller time spans is for the system (unstability?, less predictable? resources consuming? ....). Which would you say that are the lowest and highest recommended limits of the Calculation Time setting?

Thanks!

[Logread]

@alfpresa, it’s all about trying. Low inertia heating requires shorter cycles indeedx. 15mins is what I am using with electric converters that have indeed minimum inertia. The plugin takes values >= 5 mins.

[jake]

@alfpresa, thanks for your appreciation. I am afraid your suggestion of proportional vs. binary (on/off) heating control will be difficult to implement: it would require a totally different logic than what the plugin is based on.

In my Domoticz system I also have an OTGW (Opentherm Gateway) implemented. This is an in-the-middle-device between the opentherm Remeha iSense thermostat and boiler.

Nowaydays I use the SVT to control the system:
SVT controls the virtual switch 'boiler on/off'
dzVents LUA scripts is trigged by this switch and increases the iSense setpoint above the current room temperature (+0.5'C) when the switch is 'on' and -0.5'C when the switch is 'off'
The 0.5'C change triggers the boiler to start/stop heating.

With the mentioned setup, I have made the temperature dip half the size. The iSense doesn't turn on the boiler until -0.2'C below the setpoint. With floor heating this is much too late. The other way around too: it doesn't stop heating unless the temperature is +0.2'C above the setpoint.
Actually, the SVT takes care that the temperature lands on the setpoint line and more or less stays there.

To secure proper working, I made a 2nd dzVents script that monitors the behaviour of the first script. When it discovers an error, it will notifiy me and put the SVT in the 'away' mode.

Hi!

I had a little problem with the plugin 2 days ago.
Inside temperature was bellow stepping, but the heater did not start.

I restarted domoticz and everything went back to normal.

Do you know what appended?

I'm running Domoticz beta 3.8450 (Should update to last stable version when I will have time!)
