Im gonna play a llittle with the variables and see what is does to the boiler switch

[l0gic]

Well I've has a little play.

As the whole set up is dependent on the Max! Buddy script kicking out regular values, things could get messy if the system was working on outdated values.
So I've added some code to check the last update time, check it with the current time and send an email if it is outside a pre-set value (configured in the pre-set values)

Code below;

-- Thermostat are named "Stat <room name>" so a search is made for "Sta" to indicate thermostats
-- If found it will be interrogated for temperature value

-- If demand is greater than BoilerOnPercent value then fire up boiler
-- If demand is less than BoilerOnPercent minus HysterysisOffPercent then switch off boiler

-- Preset Values
BoilerOnPercent = 50					-- percentage valve open at which the boiler will be turned on 
HysterysisOffPercent = 20 				-- percentage below BoilerOnPercent to switch off the boiler

I have found a little problem with the Max!Buddy operation though.
If I use the 'Boost' function on the thermostat, Max!Buddy sulks and reports that the room is in an 'Invalid State' (script error in line 86) and stops sending data into Domoticz.
Once the boost period is over, Max!Buddy returns to sending in the values.

As the time monitoring period for me is greater than the thermostat boost period I don't get an email warning, but it is worth bearing it in mind if you want to set the email period short.
Also as no data is being sent during the boost period the logs are not updated, not a problem but again worth realising.

Had your newest script running for 4 days now.

At first the values seemed to be stuck but after a power failure of 2 hours everything started up as planned and from that point on the values looked promissing.

Her is my overview of the Boiler on switch during 3 days.

[l0gic]

Well that is looking ok as a starting point.
I'm playing with the optimum values that allow me to keep the house warm without short cycling the boiler.
I think that will only really happen once the script actually controls the boiler.

Regarding your sticking values, if you look at my last post I've set up a monitor the ensure that the values are up to date.
If we rely on them for control we need accurate values.

I'm playing with a new script for MaxBuddy at the moment to open the valves from Domoticz.
I have a wood burner in the house which is connected to the heating system.
I want to be able to override the cube settings to ensure the radiators are on to dissipate the wood burner heat.
It's bespoke to me but I'll post it up once I've got it working.

[Skippiemanz]

I havent modified the values yet.

Trying to figure out how i can control my boiler through my Radio Thermostat by a json script.

I agree that controlling the valves directly from domoticz would be a far better option and just use the cube as a sort of rfxcom for the signal transmitting.

Great how much time you've put in so far keep up the good work! and im looking forward to your next script/solution

[demoorpeter]

Hi,
I am new here and have read that the ELV Max system can be interfaced in the Domaticz software.
I have 6 radiator valves and 1 control box in use and as other users already have written: the software is bad.
Can anybody explain me (English / Dutch) how to implement them in the Domoticz sofware?
(Budy software for windows is no longer available....)
Thanks in advance!
Peter

[l0gic]

Hi Peter,
you will need to install the MaxBuddy software as it is key to interfacing with Domoticz.

You will need the MaxBuddy software (found here.. http://download.maxbuddy.de/ )
Get it working with the cube and then add the script from this thread (page 3 post from Skippiemanz )

Have fun!

Kevin

[demoorpeter]

Thanks Kevin,
I am a bit busy this week but will test it asap

regards,

Peter

[Skippiemanz]

Kevin,

Are you having some progress with controlling the valves directly?

Maybe this could be of any help to you

http://www.mega-nas.de/max/readerscript.php?host=&port=

Also ive tested with the Holiday mode, but due to some reception failure on of my temp readings is 0. So the boiler turns straight on in Holiday mode.

Is there a way to ignore the 0 temp readings?

[l0gic]

Morning guys,
the end of summer is approaching so I've had another play prior to the heating season hitting us.

I've updated the code to replace all instances of 0C with a dummy value to prevent spurious operation of the boiler when a device is not contactable.
This value is in the Preset values (ReplacementTemp) so can be changed to suit.

I've also added an email functionality to advise when a bad value is encountered.
This requires a User Variable in Domoticz called HeatingErrorTime of type time.
This will prevent an email being sent each time the script is run.

Hope this helps someone;

I've also been playing with Max!Buddy scripts and I'll start up a separate thread for those.

Kevin, I missed this post so sorry for the late reaction! I am running domoticz on my synology now so have to find out how to get everything running but the new script looks promising! Wil get back to you! And I am interested what you can do with the scripts!

[l0gic]

No problem Skippiemanz,

I'm still playing with one of the MaxBuddy scripts, so I'll upload them once I'm done.

I'm also playing with the MySensors system at the moment, I'm going to add some temperature sensors to my central heating pipe system which will ultimately control the dummy switch into the MaxBuddy system.

All the best

Kevin

Hi,

www.maxbuddy.de is down, is there a backup site for API references and also max backup ?

Hi,

http://www.maxbuddy.de is down, is there a backup site for API references and also max backup ?

Nope.
Everything has gone.

I've gained information from de-constructing published scripts from around the web.

You are pretty much on your own now, sad to say.

Kevin

[Skippiemanz]

Do you have the tar package Kevin?

[l0gic]

I do have some packages.
They are Windows only but it includes a portable version, so should be able to be used on any java enabled OS.

Gents, (and Ladies if there are any here)......

Looking for some advice/assistance please.

Has anyone come across the error where the Maxbuddy dometicz script gets 'stuck' when trying to activate a room relay defined in the tasks tab?

It seems to my (non-programmer) eye that the issue occurs when the request to change the relay state occurs when the Cube is in the disconnect state.

Domoticz is running on a Pi. maxbuddy on a laptop running XP.

Here's a small cut of the debug log:-

and on and on until a restart of maxbuddy

I've tried different hardware combinations and can always recreate the problem.

One thought I have had is if I changed the "Thermostat Switch" for a "ETH-002" relay but don't want to buy yet more hardware and find I get the same problem.
I've also played with some timers but nothing has fixed the problem.

Any suggestions much appreciated.

Thanks

Steve

Hi Steve,
I've noticed that the valves can be in a state that the domoticz script does not cater for.
A typical example would be if you boost a room for a period of time the script can not deal with the state of the valves and just fails until the boost time is over.

Short term I'd say there is nothing that can be done, longer term I keep telling myself I'll have a look at the code and get it sorted.
It shouldn't be too hard to put a print statement into the code to show the state of the valve and wrap some code around that condition to deal with it...

All the best

Kevin

Edit - Just noticed that you have issues with the scheduler rather than the domoticz script - oops!
Not had any(obvious) issues with that.
Perhaps a call to the suppliers help desk?

Hi guys,

I've been reading this with interest.

I've tried StellaZ and Smartwares and been VERY unimpressed. Danfoss is over priced and doesn't tick all the boxes.

How do you guys rate this stuff? I've been looking at the EQ-3 on conrad-electronic.co.uk. I assume that the minimum I need for testing is a cube and 1 trv? or is a thermostat essential?

Thanks for any advice/tips
