Hmm, this could probably be improved, will look into it. Meantime as Chris suggested above you can make some suitable connections to the Mains power loss connection. Aside from local alerts,...

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...

Yes of course its always a good idea to manually back up files you have laboured on :), but also Cortex will make an automatic backup before it saves a database. I suppose this doesn't prevent you...

As a general comment, deleting objects and disabling/enabling network nodes is better done when the network is stopped. In the latter case if you disable the network nodes whilst the network is...

Just to put things in perspective I think this might be one of the largest installations coupled with the smallest computing platform :). My last information was around 250 modules totalling 1088...

A temporary change will also be removed at midnight and if the network is stopped/started. A return to normal profile can be made to occur based on other signals via the HVAC Heating (or Cooling)...

Firstly I should make clear that I am from IDRATEK. As my usual mantra goes ... there is a difference between home automation and home control. So collecting together sensors and actuators and a bit...

Chris,

So is the duct tape experiment not entirely effective because it still occasionally allows motion at one level to be seen by both sensors or is it that it is too aggressive and then doesn't...

Well as usual it depends on the specifics, but you could check out our system (IDRATEK). It provides a range of sensors and general signal interfaces together with software which talks to these and...

Oh I see what you mean now. Interesting that it just seems to employ two wires, suggests that maybe the power to the sensor perhaps gets pulled low for a short burst upon touch? Would need to know...

I think not as they appear to be inline mains switches i.e use mains as a power source

Sorry its taken a while to compile something. It isn't exactly an idiot's guide but hopefully might point out some of the important considerations. Use link:...

Don't know if I've posted these before but just out of interest here is some data captured from a property some time ago when it was empty and doing some heating/cooling tests. Shown are temperature...

I suppose it could be a thermistor connected into a QAI but obviously the main problem is how to route the wiring. If very thin wire such as enamelled copper or very thin flat riboon are used then...

Do you mean specifically relating to the suggested gas monitoring idea or more generally?

I'm not sure I understood the question so clearly, but anyway Cortex already has sophisticated heating and cooling controllers (HVAC) within it so you wouldn't ordinarily have to create your own...

For new users please note that we now primarily provide a USB rather than RS232 network interface.

QBA: There was a reported issue with HVAC energy analysis caused by HVACs which had no connected...

'Lightweight' I think only applies to Cortex's required processing power not the application's capabilities ;). As Chris points out it depends on whether you intend to include processor intensive...

Allan,

Always good when someone else does the work for you :). Thanks for that information. I looked at the LEDlite product description via your tlc link. Looks like the LED driver is separated...

Toscal, thanks for that document link - its a good indicator of the present vagaries of dimmable LED technology.

Allan, we have fiddled around with mapping tables and even the triggering schemes...

Chris,

There is of course an existing 'Verifier' object in Cortex which allows you to set up some expected criteria to be checked a certain time after an event and an action taken if the criteria...

In the first example do you mean like a multiway conventional swich operation? Unless you are running IDRATEK relays in conjunction with conventional switches this should not happen, i.e you just...

Please send us the license details you are presently working with and the version of Cortex.

Sorry I just noted the question part in your post of December 13th... The DFP fits over a dual gang...

Well from what you've described you've certainly come to the right place :). To set up a simple physical network, as you have correctly deduced, you will need a PC/IDRANet interface module (presently...

Yes I should imagine a BC547C would do the job (form a darlington pair with the IR phototransistor). I'm not sure if the OPB720A-06Z would distinguish between the variation in reflectivity at close...
