Analog_Sensor and expired sensor reading

[Lieven Hollevoet]

Hello,

I'm trying to couple readings from my ambient lightlevel sensor with Misterhouse. The reason is that I would like to use Misterhouse to control some lights and our window blinds, and that I would like to use the real light conditions instead of the ones calculated by Misterhouse.

Some background: the sensor itself reports its readings wirelessly to a 'gateway' that is on my LAN. Misterhouse then periodically interrogates the gateway to get the readings. The gateway keeps a counter that is reset every time a valid RF packet is received. In this way, I can know how fresh the value is that I read from the gateway. If for some reason the gateway is not receiving RF packets, I don't want Misterhouse to react on an 'old' value. If the counter is bigger than 250, I consider the reading to be too old to be used.

The basics are already working (see attached code file), but I have a specific question concerning the 'freshness counter' in the gateway.

I'm using an ANALOG_SENSOR to keep track of the current lightlevel (between 0 and 100%). Is there a way to make clear that the current measurement that is done for the analog sensor is not valid any more?

What I'd like to obtain is that if I request the value of the analog_sensor item in usercode,  I could first verify if the value is still valid.

Theoretical example user code in combination with attached file:

# Switch on the desklight if it is getting dark
my $desklight_auto_on_allowed = 1;

if (new_minute) {

    my $lightlevel = $sa_lightlevel->measurement();

 
    if ($lightlevel > 70 and $sa_lightlevel->valid()) {
        $desklight_auto_on_allowed = 1;
    }
    if ($lightlevel < 30  and $sa_lightlevel->valid() and $desklight_auto_on_allowed){
    &::print_log("It is dark outside ($lightlevel %), switching desklight on...");
    $desklight->set("ON");
    $desklight_auto_on_allowed = 0;
    }
   
}

Can somebody point me in the direction on how to solve this please?

Kind regards,
 Lieven.

Since Analog_Sensor is derived from Generic_Item, you can use the get_idle_time method on that object to return the seconds since it was last set.

Hello David,

perfect, indeed that's what I was searching for.

Thanks,

Which light sensor are you using?  Is it something custom that you hacked up?  I have two of the 1-wire temperature/humidity/solar sensors from Hobby Boards, and I haven't figured out how to read the solar sensors yet.

It is a custom design, so I'm afraid I won't be able to help you with the Hobby Boards one.

I made a description of my setup here: http://lika.be/wp/2009/06/self-powered-wireless-ambient-light-sensor/

Greetings!

I'm hoping one of you might be so kind as to point out an obvious route of
enquiry.... after a power failure and an SVN update, my previously working
MH is now giving me an error and failing to start:

  10/15/09 03:00:11 PM: Global symbol "$benchmark_tickcount" requires
explicit package name at (eval 411) line 3222.
Global symbol "$benchmark_tickcount" requires explicit package name at
(eval 411) line 3222.
Unmatched right curly bracket at (eval 411) line 3224, at end of line
syntax error at (eval 411) line 3224, near ";

}"
Line 3217:  }
Line 3218:
Line 3219:
Line 3220:
Line 3221:
Line 3222:     $Benchmark_Members{'insteon'} += &get_tickcount -

Line 3225:
Line 3226:  sub insteon_table_loopcode {

Any ideas what might have chnaged that my previously working insteon.pl
might no longer work?

Many Thanks,
Tom M.

Found my problem.  Don't know how it got there, but as the message below
indicated, I had an extra curly brace. Sorry for wasting your bandwidth.
(My excuse is that I'm jetlagged, and was stressed because my automation
was broken!)
