Hi all,
has anyone got an idea on how the wireless smokedetector SD10 works, especially in regarding to powerhome? Does it work the same as the Hawkeye? (sends an a1 command through RF which can be received by a transceiver TM12?) Any other (hardweare)ideas on how to add a smoke detector to Powerhome are welcome too.... I've made a macro and trigger in powerhome which do:
1: send an e-mail to my smartphone and my wife's smartphone
2: Open the front and backdoor shutter
3: let the frontporchlights blink
Now fot the hardware!

I don't know about the SD10 specifically, but the Ademco 2112/24ATR Smoke Detector provides a relay output. I wired the relay into an x10 door/window sensor transmitter. Powerhome then receives the smoke or heat alarm via the extended RF x10 code. Powerhome then gives a verbal warning that echoes through the furnace ducting, plus email, phone text, and pager notifications.
One caution-- make sure you know how the sensor behaves if the power source (AC, DC, or battery) fails. Some of my sensors "trip" upon a power outage (fortunately I also get a power outage warning so I can then properly interpret any warnings).
I like your idea for opening the shutters-- that way if you're not home and you get a smartphone message, you can ask a neighbor to look inside. One other thing that would be useful would be to shut down HVAC and/or electrical power (assuming that won't further compromise safety) in case either is contributing to the fire.

That was my idea also, but then to use an SM10 universal transmitter which in turn sends an A1 command to the address. I've already seen some snmoke detectors which have a relay-output. The best would be however to have them connect to eachother through the ISM-band (895 mHz) and have the detector the closest to the server send the command through the SM10, however, your idea of a verbal warning is outstanding, but since PH runs on a Pentium 100 I think this Pc is too slow for Verbal Messages.... (I could however put a faster PC/laptop on my wishlist)

That will be something to expiriment with... I could have a formula watch the serialport for a 0x3a message and go on with that!

Well, my HVAC is not only secured with fuses but also with earth-leak detectors, they act on a difference of 15mA and shut the whole system down. My 2 servers and emergency ligthing are the only devices that will continue to work. I could however have a 3rd earth-leak detector connect to another SM10 which in turn sends an apropriate command to the server which in turn shuts the whole house down after the shutters have been opened....

Wow. Quite a setup you've got there.
I think it would still be logical to shut off HVAC, even with the protections already in place. If one were to accidentally leave that apple pie in the oven and go to sleep, then the billows of smoke wouldn't get pumped into your bedroom.

Well that is the least amount of work. I just have to exchange the main-switch with an X10 rail-switch and I am done. I have seen several smoke-detectors... Det. that are RF-linked, linked with a cable..... the best of both worlds would be a set of three that are radio linked and one has AND radio linkage AND a relay output. However up until now I haven't found it yet...

I have bought 2 smokedetectors which can be connected through a 2 wire-cable. The detectors give a 9volt signal to eachother when an alarm is given. Next is to connect this 2 wire-cable to an SM10 unviersal-alarm-module. This module will give a signal at address a1 and the Macro which was already programmed is executed. In theory it'll work... so now I am going to order the SM10 and in a week I will know the outcome of this small project...

Here is an update on the smokedetectors:
The detectors are in place, connected both to the SM10 and the macro perfectly executed including mailwarinings to my smartphone (Thanks TonyNo for mailing me your macro on e-mails) Also when A fire-alarm is given, the temperatures (of another project I was working on) are contained in the warning e-mail. The HVAC is switched off when an earth-leak-detector is activated and the server(s) run on a UPS as well as the lighting and the shutters. Total running time on the UPS for the server(s )is about 17 minutes, litghing can run on UPS for 2 hours, the Shutters can bleed the UPS dry when they have been activated 3 times...
