Hi,
I would like to control my Powermax via the RaspberryPi, with a web gui.
Eventually I want to control the Powermax via an android app.
I found some hardware in my box and tried to connect my Pi via an USB-serial converter to the Powermax connector.
my usb-serial device has an old prolific chip which is not supported under windows8.
So I can't try the software package that comes with the Powermax to program the alarm system.
Now I'm stuck in receiving and sending the right data from the Pi to the Powermax.

I hope someone can help me to get this connection up&running

------------------------------
Some other data so far
------------------------------

The serial adapter is connected as follow:
PI - Powermax
GND - GND
RX - TX
TX - RX

Powermax pin's found @ domoticaforum.eu/viewtopic.php?f=68& ... 152#p53758
------------------------------------
|?0V GND TX RX 3.75V |
|?0V ?3V ?0V GND 3.75V |

I can connect to the serial adapter via:
# screen /dev/ttyUSB0 9600

When I connect the tx and rx on the serial adapter together I get my own echo/reply's when I'm pressing some keys.

Hi,

The type of Powermax you are trying to connect to is not clear from your post. Just so you know, a Powermax+ has a different pinout for the serial connector. If you do have a Powermax+, have a look at:

http://www.domoticaforum.eu/viewtopic.p ... =45#p63022

It describes in some detail the serial connector for the Powermax+. I've used an FTDI USB-to-RS232 converter that works really well. I also tried a Prolific based cable, but never got that to work, I got no response whatsoever from the Powermax+ using that cable.

I've got a Powermax Pro.
My connections look exactly like those on the pictures on:

hello everybody!

I want to connect my Powermax Pro with Raspberry Pi, but using the GPIO pins. I would use 6 GND, 8TX, 10 RX.

I know nothing about electronics. I have read that it is necessary that the voltage is 3.3v and it seems the PC port / IP and raspberry Powermax work to 3.3 v

Can it be done directly without any converter?
thanks

No. You dont need use a serial USB adapter. Raspberry and powermax use the same TTL voltage (3.3v) so you can connect both directly.

I'm looking for the same.

Best regards

I haven't put any energy in the project as I was stuck on receiving any serial data from the powermax.
Maybe I have to powerdown the main powermax controller, just cut the AC and battery's so it get's a hard-reset.

I still have all the hardware, but I'm unsure if I have to run the windows programming software to "unlock" the serial-port.
Anyone knows the procedure to get the serial up&running?

My English level isn't very good....

How are you connect both? With gpio rx tx or USB ttl adapter?

Regards

I've used a USB ttl adapter. But it doesn't matter which client, right?
I just need to know which codes to send to the controller.

Hi,

I want to do the same : connect my RPi to my powermaster30 in order to manage my alarm and got sensors informations. It works with vera (cf micasaverde forums) but no information about Rpi but this topic. Vicknet talk about a checksum to initiate the connection with openwrt but i haven't seen any how to

Has anybody got success with Rpi ?

@kingofnuls:

The PowerMaster30 isn't 100% compatible with the PowerMax protocol. The magnet contacts will work fine, BUT you can't get easily the PIR (motion sensor) information from the PowerMaster. I am still analysing protocol information, and I think i got an idea how to "guess" which PIR is detecting movement. It won't be a 100% solution, but it seems to work 97% (or more) in my case.
I think will have this worked out in a few weeks, but then you need to implement it in the application yourself to be able to use it on the Pi (i will only document the behaviour and implement it in DomotiGa).

Hi Alex,

Because of (thanks to) you, i've connected my french Powermaster30 to a Domotiga3 Rpi B. I'm learning to use Domotiga which is more difficult than domoticz (imho). But your work is fantastic and i can now send my magnetic contacts informations and my alarm status to my domoticz controller. Domotiga will also be in charge of SMS communication.

For your information, in order to have the connection up with my PM30, i had to put the right download code.

THanks again for your hard work.

PS: Have you in project to switch on and off the alarm panel ?

Best ragards,
