ELV Max! Heating control system

[l0gic]

Hi guys,
wow! you lot have been busy!
Very impressive I must say and a much smarter solution than the old Max!Buddy option. It was needing a few sticking plasters on it to keep it working.

I'm going to have a go at implementing this on my Windows system, I'm guessing getting the lua and luarocks working in Windows will be a bit of a challenge, but what the hey - it's only time.

I'll be back once I have an installed lua subsystem on my box.
Plus I'll document it for addition to the wiki.

great work guys!

All the best

Excellent news!
Welcome back

Cheers Sean.

Quick question, is the luarocks luasec actually required?
I've managed to install lua and luarocks after a bit of pain and faffing around, but the luarocks luasec is being a real pain.
Looking at the scripts I can't see luasec being loaded at all.
So before I put too much effort into it I'm wondering if it will be needed?

Also, can the script manage the situation where a room has a thermostat with two or more radiators?
I have a stat in my front room with two radiators plus the conservatory radiator also included as the physical rooms are combined.

Looking good, should have a working system tomorrow (hopefully)

All the best

Good question.
I think it was a possibly a requirement in another project that a lot of this was originally based on but may not be used. I'd try running the test script and see if it works. If it does... well the rest may and we can update the wiki accordingly.

As to 2 rads, it shouldn't be a problem as the max script takes it's temp reading from the wall stat and that in turn forwards it's set-point to the rad valve/valves associated with it. The second script... which didn't you write the original?... looks at the rad valve open % and doesn't much care which rooms or how many. At least that's my understanding of it.

Good luck with your set-up, I'm REALLY pleased with how mine is working now... more importantly, the Wife is REALLY pleased!

A happy customer here also! Would be nice and so Much easier If the luassec part could be skipped.. Looking forward to you're findings!

In the meantime im having a look at this interesting subject https://r.tapatalk.com/shareLink?url=ht ... are_type=t
Intelligent Multi-Zone Heating Script witch would be the ultimate addition to this system!

i cant see whats up with names, Temps will not update in Domoticz, Setpoints will not update in Domticz from Max But max will change if i change Domoticz setpoints.
Any help or ideas greatfully recived

Dave

Temperature will indeed not be updated if you don't have wall thermostats. Earlier versions of the script updated the Domoticz temperature device(s) with the actual temperature(s) received from the valves, but I removed that since the valves only send the current temperature when the motor is running. That didn't give very usable day graphs for the room temperature. We still need to explain this in the Wiki, actually you don't even have to create temperature devices in Domoticz if you don't have wall thermostats.

Apart from that, it seems you have everything set up correctly. The log says the Domoticz setpoints are updated, and it seems to send the commands. At least I assume so, because it says "Fetching url...", which is the expected message since I use API calls to do this. That is because of a bug Domoticz where updating setpoints via lua "UpdateDevice" commands results in script timeouts). Only the commands apparently never reach the setpoint devices. Are you using the right port number for the API calls to Domoticz?

You could try and replace (twice)

Code: Select all

table.insert(commandArray, { ['OpenURL'] = 'http://127.0.0.1:'..DomoticzPort..'/json.htm?type=command&param=udevice&idx='..otherdevices_idx[name]..'&nvalue=0&svalue='..setpoint})

with

Code: Select all

table.insert(commandArray, { ['UpdateDevice'] = otherdevices_idx[name]..'|0|'..setpoint})

which could give the notorious timeout messages but should work regardlessly.

P.S. I now see all your valves seem to report an actual temperature... This would contradict my story above. Can you maybe check, e.g. by running the lua test script a couple of times, if those temperatures are actually updated regularly? Maybe you have other valves than myself (I use the basic model)?!

If your valve temperatures are updated regularly, or if you don't have a problem with virtual Domoticz temperature sensors that are only updated every now and then, you can get temperature reading back into the script again by adding this line:

Code: Select all

		  table.insert(commandArray, { ['UpdateDevice'] = otherdevices_idx[room]..'|0|'..temp})

directly below the "if not useWMT then" line. This will update the virtual temperature sensor(s) named after the room name(s), using the current temperature as reported by each valve.

Hmm, having an issue.
Lua & Luarocks compiled and installed fine.
Installed Luasocket & Luabasexx, again fine.

Trying to run the script_time_EQ3_Cube.lua inside Domoticz (in the script directory) causes an error

Code: Select all

Error: EventSystem: in C:\Program Files (x86)\Domoticz\scripts\lua\script_time_maxCube.lua: error loading module 'socket.core' from file 'c:\program files (x86)\lua\5.2\lib\lua\5.2\socket\core.dll':
The specified module could not be found. 

However, running it from the command line it runs without the error (doesn't particularly do much though - not sure if it would)

I'm suspecting a clash between Lua versions.

I've set LUA_PATH_5_2 and LUACPATH_5_2 up OK. From the error it seems to see the core.dll file but cant find socket.core in it.
Luarocks install luasocket executed fine so I can only assume it is installed ok.

Anyone have any ideas at all?
NOTE - I have not been able to install luassec but I can't see that being the issue as it would have been indicated as a dependency if required.

Hi kevin,

What's in script_time_EQ3_Cube.lua?

Did you try the test script to do a basic read?

Hi guys, finally I`m able to run script but there is error:

Code: Select all

2016-11-08 15:45:01.078 Error: EventSystem: in /home/pi/domoticz/scripts/lua/script_time_max.lua: /home/pi/domoticz/scripts/lua/script_time_max.lua:138: attempt to concatenate field '?' (a nil value)

Does anybody have any idea what is wrong? I only copied script from Wiki.

Thanks

[Skippiemanz]

Are U sure youve got the latest version from the wiki?

I will compare my version with the wiki version tonight to make sure.

Yes. Copied few minutes ago.

Do you have Window sensors anf/or Wall thermostat? Could you post the result off maxtest. Lua

I have window sensor.

[Skippiemanz]

Ok. Did you name it like this Entrance Room-Sens?

That way it's ignored by the scripts but stil sets the valves low when Window is open

Fuck... I'll do it... Sorry. Thanks

No problem, i think it's not yet marked in the wiki

It isn't there. I'll send update about Lua installation on RPi image...

Ok! Please update the wiki on the lua part and If you have time also about the Window sensors!

Windows sensor is type "switch" in Dummy?

The Window sensors are not(yet) seen in domoticz so no devices are Needed
