Python Plugin: Smart Virtual Thermostat

[Logread]

I'm impressed with your thermostat.
In my house is the floor heating, or will the thermostat work with it?
Floor heating has high thermal inertia.

Do you intend to drive (i.e. switch on/off) the floor heating with the plugin ? If so you will indeed need to use fairly long calculation periods... I cannot give you guidance, but you need to monitor how the heating parameters best beheave (look at how constT and ConstC evolve over time in the uservariable used by the plugin) over a few days.

My mountain vacation place also has floor heating, but it is self regulated to only provide the minimum base heating required to maintain 10 degrees C of ambiant temperature when no one is there... all heating above that level is with electric convectors that are driven by the plugin, and I am pretty happy with that combination.

I found out after this plugin was released that no one has the same setup and needs in terms of heating. Hopefully the plugin is flexible enough to help as many users as possible, but clearly it is all case by case.

Hi

The below errors happen after one or two calculation cycles of logread's thermostat plugin. Can someone help me? I'm not sure if it's bug with how outside temp. gets set to "none" (line 332 in plugin.py) in the internals or a problem with my system.

System: raspberry pi model B, raspian jessie lite, python 3.4.2, Domoticz beta Version: 3.8755

@etampes,

Thznks for posting the log... I’ll look into this... bear with me pls

EDIT: @etampes,
I just pushed a new version that should fix the bug you uncovered. I indeed think it is related to the fact you have no outside temperature sensor in your setup. Can you please update to version 0.3.6 (use update instructions from the wiki) and report if this has fixed the bug ?
Thanks

[etampes]

Thanks for this, I'll update it.

Version 0.3.8 is available from GitHub for install/upgrade as per instructions at https://www.domoticz.com/wiki/Plugins/S ... ostat.html.
It fixes a logic flaw uncovered by @napo7 for the minimum heating level (v 0.3.7) and includes some minor improvements in the code (v 0.3.8).

Please keep reporting possible bugs and suggestions.

I've just installed this plugin onto a running Domoticz (latest beta) using the instructions on the wiki page. As soon as I enable the new hardware device, domoticz crashes. No debug messages or anything that i can see.

The only remedy is to rollback the database to the previously hourly backup.

Any clues on where to start?

It seems many people, but not all, have experienced crashes related to the python plugins framework, that is still a beta feature. If you do a search on the forum for « python crash » or « plugin crash », you will see many cases and this does not seem to be associated to a particular plugin. The following post might be relevant it seems for an issue with the latest beta: viewtopic.php?f=6&t=20899#p161669

You may try to downgrade to a prior beta (or the latest stable) or try some of the fixes others have found (like compiling domoticz yourselves rather than downloading the stock binaries).

Thanks for the support.

I read through the thread and knew there had been a problem with the Python framework, however I assumed it had been fixed. I’ll do some digging and report back.

[napo7]

Yes, it's a know feature of the latest beta
Every python plugins makes it crashing...
Devs are still searching the cause... Wait a moment

I can also confirm that the stable release doesn't have the problem.

Yes, I reverted to the latest stable release and it works now.

I want to use it to control the temp in my wooden office/man cave at the bottom of the garden. It’s reasonably well insulated but I may have to play with the tuning parameters.

[garethhowell]

After a reboot, SVT started crashing domoticz again. I’ve removed it for now until the python framework is stable.

Can you help me with that?

Did you allow password free access to domoticz for IP 127.0.0.1 ? Is domoticz reachable on port 8080 ? Is there a firewall rule that could interfere ?

[Logread]

Any idea?

Quaxx

Frankly no... besides making sure all steps for installing were followed. Did you try other python plugins to understand if this is generic rather than related to this particular plugin ?

[Quax1507]

Hmmm, seems to be a python problem!

I just tried Sonos plugin which crashes, too!

What could be the reson for that?

[blauwebuis]

There seems to be a python issue in the current beta:

I've just built domoticz from source and re-enabled SVT. So far, so good.
