Raspberry PI + RFXCOM RFXtrx433 +Oregon Scientific sensors + http://www.domoticz.com/

With this system you can log temperatures, humidity, wind, rain.
You can also access the system from remote.
In addition you can control HomeEasy, ByeByeStandBy, LightwaveRF, X10 and more.

Many X10 items

One thing to bear in mind is that a particular database file name is linked to historical data files using that name. In other words its ok to change the name of backups but to view the data you will have to change the name back to that which created the data. Hence good idea not to change the name of the active database. If you absolutely need to do that then its not impossible to link it to the history data but a case of manually renaming history data files. If you look at these you will understand how.

Hi,

You could have a look at Geovision, see: http://www.geovision.com.tw/english/...VASManager.asp
The feature list seems broadly inline with what you're after.

I think the Comfort alarm system can do most of what you want too, although I'm not sure about the CCTV integration. If you've got a smart phone you could access your CCTV/IP camera separately though.
See: http://www.cytech.biz/page.php?page=Overview and scroll down to the "Door Station Intercom" bit.

HTH,
Tim.

Easy Power Management output from Wiser or Touch Screen

blacky7 — Fri, 17 May 2013 02:44:18 GMT

Hi All,

I wrote some logic for a client who wanted a text output rather than looking at the pretty graphs. Thought someone here might also find it useful for your own purposes.

It displays the last 12 months of Current Measurement Data (from the 5504CMU C-Bus module) and gives an easy to read output to assess your power use for the period. You just go into PICED, select your project and 'refresh project from unit' so it downloads the latest power CSV file. Of course, don't upload an earlier project to your screen or Wiser or you will overwrite your power data.

You can run this in the PICED logic window by setting your 'logic options' in the logic window to 'Allow use of all functions for testing' and 'Send WriteLn output to log'. You then look for the output in the PICED log file under the 'View' pull down menu in the main PICED window.

Output is as follows:

Code:

C-Bus Network Power Measurement

     

Total Energy (in kWh) Use Measured as at 17/05/2013

This Months Power Use To Date  = 665 kWh

This Months Expected Power Use = 1241 kWh

    

Previous 12 Months

    April 2013 Power Use = 1238 KWh

    March 2013 Power Use = 2166 KWh

  Febuary 2013 Power Use = 2324 KWh

  January 2013 Power Use = 1527 KWh

 December 2012 Power Use = 1514 KWh

 November 2012 Power Use = 1826 KWh

  October 2012 Power Use = 1607 KWh

September 2012 Power Use = 1353 KWh

   August 2012 Power Use = 1708 KWh

     July 2012 Power Use = 1850 KWh

     June 2012 Power Use = 1784 KWh

      May 2012 Power Use = 1632 KWh

     

Average Monthly Energy Use          =  1711 kWh

This Month's Expected Power Use     =  1241 kWh

This Month's Energy Use vs Average  =     -27.5 %

Setup in a new module in PICED Logic called [Power Monitor] (or whatever)

Code:

WriteLn('C-Bus Network Power Measurement');

WriteLn('     ');

DateToString(Date, Today);

DataString := Today;

WriteLn('Total Energy (in kWh) Use Measured as at ',DataString);

MonthPower := GetRealIBSystemIO("Power Meter Total Energy",3, 1, 0, 0, 0, -1);

Format(DataString, 'This Months Power Use To Date  = ', (MonthPower/1000):0:0,' kWh');

WriteLn(DataString);

CMonthPower := GetRealIBSystemIO("Power Meter Total Energy",3, 1, 0, 0, 1, -1);

Format(DataString, 'This Months Expected Power Use = ', (CMonthPower/1000):0:0,' kWh');

WriteLn(DataString);

WriteLn('    ');

WriteLn('Previous 12 Months');

countup := 1;

while countup <= 12 do

  begin

  MonthPower := GetRealIBSystemIO("Power Meter Total Energy", 3, 1, countup, 0, 0, -1);

  Format(DataString, ' Power Use = ', (MonthPower/1000):0:0);

  MonthValue:=Date-(31*countup);

  DecodeDate(MonthValue, CYear, CMonth, CDay);

    case CMonth of //Select Month

    1 : DMonth:='January';

    2 : DMonth:='Febuary';

    3 : DMonth:='March';

    4 : DMonth:='April';

    5 : DMonth:='May';

    6 : DMonth:='June';

    7 : DMonth:='July';

    8 : DMonth:='August';

    9 : DMonth:='September';

    10 : DMonth:='October';

    11 : DMonth:='November';

    12 : DMonth:='December';

    end; 

WriteLn(DMonth:9,CYear:5,DataString,' KWh');

  countup := Succ(countup);

  MonthAv:=MonthAv + MonthPower; 

  end;

WriteLn('     ');

WriteLn('Average Monthly Energy Use          = ',(MonthAv/12)/1000:5:0,' kWh');

Format(DataString, 'This Month''s Expected Power Use     = ', (CMonthPower/1000):5:0,' kWh');

WriteLn(DataString);

WriteLn('This Month''s Energy Use vs Average  = ',(-((MonthAv/12)-CMonthPower)/(MonthAv/12)*100):9:1,' %');  

DisableModule("Power Monitor");

It is designed to just run once and you can use it from PICED or your touch screen using a button etc.

and you need these variables defined in 'Global Variables'

Code:

Global Variables

countup : integer;

DataString : string;

Today :string;

s :string;

MonthPower : real;

CMonthPower : real;

CYear:integer;

CMonth:integer;

MonthAv : real;

DMonth:string;

CDay:integer;

MonthValue:integer;

In the case you wanted to write the output to a text file to keep as a power history, either on a Colour Touch Screen or from PICED after downloading the power data from the touch screen, use the following:

Code:

AssignFile(file2, '12Month_Power_Data.txt');

ReWrite(file2);

WriteLn(file2,'C-Bus Network Power Measurement');

WriteLn(file2,'     ');

DateToString(Date, Today);

DataString := Today;

WriteLn(file2,'Total Energy (in kWh) Use Measured as at ',DataString);

MonthPower := GetRealIBSystemIO("Power Meter Total Energy",3, 1, 0, 0, 0, -1);

Format(DataString, 'This Months Power Use To Date  = ', (MonthPower/1000):0:0,' kWh');

WriteLn(file2,DataString);

CMonthPower := GetRealIBSystemIO("Power Meter Total Energy",3, 1, 0, 0, 1, -1);

Format(DataString, 'This Months Expected Power Use = ', (CMonthPower/1000):0:0,' kWh');

WriteLn(file2,DataString);

WriteLn(file2,'    ');

WriteLn(file2,'Previous 12 Months');

countup := 1;

while countup <= 12 do

  begin

  MonthPower := GetRealIBSystemIO("Power Meter Total Energy", 3, 1, countup, 0, 0, -1);

  Format(DataString, ' Power Use = ', (MonthPower/1000):0:0);

  MonthValue:=Date-(31*countup);

  DecodeDate(MonthValue, CYear, CMonth, CDay);

    case CMonth of //Select Month

    1 : DMonth:='January';

    2 : DMonth:='Febuary';

    3 : DMonth:='March';

    4 : DMonth:='April';

    5 : DMonth:='May';

    6 : DMonth:='June';

    7 : DMonth:='July';

    8 : DMonth:='August';

    9 : DMonth:='September';

    10 : DMonth:='October';

    11 : DMonth:='November';

    12 : DMonth:='December';

    end; 

WriteLn(file2,DMonth:9,CYear:5,DataString,' KWh');

  countup := Succ(countup);

  MonthAv:=MonthAv + MonthPower; 

  end;

WriteLn(file2,'     ');

WriteLn(file2,'Average Monthly Energy Use          = ',(MonthAv/12)/1000:5:0,' kWh');

Format(DataString, 'This Month''s Expected Power Use     = ', (CMonthPower/1000):5:0,' kWh');

WriteLn(file2,DataString);

WriteLn(file2,'This Month''s Energy Use vs Average  = ',(-((MonthAv/12)-CMonthPower)/(MonthAv/12)*100):9:1,' %');  

CloseFile(file2);

DisableModule("Power Monitor");

Please note this code was knocked up quickly till late last night and may have some minor bugs. If you find one, be nice and PM me rather than replying and I will correct it for everyone.

Otherwise Enjoy and I hope you find it useful.

HVAC Object with no presence connection, what profile does it use?

Remember that the Set-Point at any moment in time can be influenced by a number of factors such as occupancy, outside temperature compensation and and any user offsets. So I'd say its pretty useful to display this. Obviously if you don't use cooling then better not to clutter with latter. Also in the Setup | Options | HVAC and Radiator setting my own preference is for Icon to show the Set-Point

Thanks Karam!

HVAC configuration

chris_j_hunter — Thu, 16 May 2013 09:01:49 GMT

Hi Paul -

we put one in every heat-transfer circuit, so one per pump - bar solar, which could get too-hot - so, one in the loop between ASHP & its thermal store (235 litres), one per UFH circuit (ie: two, one per floor, with the circuits including three & four loops), and one per inter-'store circuit ...

we tried to devise a lower-cost way, perhaps sharing them, but extra motor-valves would have been needed ...

all pipes, all around the house, are insulated, using standard stuff - but it's surprising how the losses add-up - we lose a bit more than 0.5degC between 'stores, three or four times that between ASHP & 'store, and a touch more even than that between vacuum-tubes & 'store - we should have done the sums, rather than rely on following what we thought was normal practice ('stores & sources are not co-located, the runs between being in the range 10 to 15m long - 'tubes on the roof, tank in basement, ASHP in yard, tank in sub-basement, etc) ...

of course, we know this only because we've clipped sensors onto each end of each run (sensor resolution is �0.5degC, so also need to try to take that into account) ...

v.glad you're including at least one flow-meter - so few people do and, without it, there's no way to know (rather than speculate or think wishfully) about heat transfers ! Only exception to that is with heat-exchangers - we've one where we measure flow-rates on one side only, and compare the temperature deltas to deduce the flow-rate on the other ...

thermo-syphoning (and other induced flows), yep, did wonder ... we added some solenoids to the DHW secondary-return circuits because we thought losses there were too great (despite being well insulated), to ensure only necessary loops were activated at any time in response to Presence - 'though we've yet to try it / them (needs us to add some logic to our Cortex database - part of the 10%) ...

Gas usage monitoring

cliffwright — Tue, 14 May 2013 13:45:43 GMT

Maybe I am just being dense - but I really am looking for an idiots guide here - a total step by step instruction of;

1) You'll need an XYZ dooflop
2) Connect pin 1 to input A
3) Connect pin 2 to input 2
4) Point the dooflop at the moon and stand well back.

I'm just not familiar with electronics, resistances etc and don't want to blow anything up.

Software is my 'bag' not electronics.

Hope someone can help.

Managing UFH Manifold and Mixing Valve

Paul_B — Sat, 11 May 2013 14:13:20 GMT

Afternoon all,

Resurrecting an old thread as it relates to what I am trying to determine. I have recently replaced an old non-condensing boiler with a wonderful Viessmann model with weather compensation. This was stage 1 of my plan and to some extent I now realise I may have installed a very capable boiler only to stopiing using some of its features in subsequent stages, but on the plus I know if things don't work out I have a good foundation.

Stage two is happening now and this sees the use of a 750L thermal store for providing flexibility in heating our home as future stages see the introduction of solar thermal, solar PV and wood burning stove with back boiler. The store has 100mm of insulation so expected heat loss is 0.5 degrees over 24 hours. I am also moving from a vented to unvented system. My plumber friend is currently going bald trying to make this work and still use as much boiler functionality whilst taking into consideration that solar is not available today only in the future.

Stage three is the distribution side of space heating and DHW. Again plans are afoot to move from radiator based system to UFH, one room has been completed but not commissioned. I'm therefore thinking about a UFH manifold and whilst researching came across the Emmeti M3Vwhich can combine hot and warm water distribution to centrally control radiators and UFH. The manifolds have electro-thermal heads so ideal to control via Idratek. I may also consider the addition of energy monitoring in the form of direct read meters with pulse output (1 pulse = 10l). But before I go and order it I was interested in what others have done and any considerations?

"unbinding" HR80

des0tds — Wed, 08 May 2013 20:43:23 GMT

Hoping SensibleHeatUk is out there still ... or someone else as good!
This system has given problems and more problems.
* As with the original discussion I've decoupled several HR80s, which seems to have worked fine. I haven't decoupled all, then recoupled some; just decoupled the annoying ones. Any issues with that?
* I've had rooms sweltering when the radiator's are set to 5 deg C! Two possible causes I think I've identified: 1) battery is low, but not low enough to trigger the "battery low" message; 2) the controller motor not being able to rotate far enough to shut the valve - attaching the HR80 by hand wouldn't get the motor close enough to the pin, but tightening it up (hard!) with a pipe wrench seems now to have worked. Do these sound like "normal" things?
* more worryingly right now - i've set the heating to "off" on the CM67Z, but the "always on" radiator is still always on. Assumed it would go off when the heating was turned off. Any suggestions?
Thanks!

Good luck with that!

My system struggles with more than 8 FHT 8's. The problem is the radio frequency gets really busy and latency becomes a problem.

Have a look at the Cul devices from busware , they are cheaper.
