I need to check my notes, but i remember that when i send a download request with an invalid pin, the PowerMaster30 responded with the auto-enrollment (set new pin for the PowerLink). After this, the keep-alive started. If your device is in error state, check the CVisonic.class code of DomotiGa, it ...

@lmaurice: I am sure if it is possible to have both the PowerLink2 module and RS232 communication (i only have RS232). Do you acknowledge the "0xAB 0x03 ..." (=keep-alive) etc message, if you don't and the PowerMax does NOT go in an error mode, then the PowerLink2 is still active. If i don...

@lmaurice:

Just to confirm, you properly acknowledge the message(s) send by the PowerMax? Else the communication will stop.

Which commands are you sending to the PowerMax? For almost all requests you have to be in the "download" mode first.

(little bit late - sorry) New version 1.0.013, you must upgrade your database. Please make a backup of your database and DomotiGa directory tree first! Because of the big database change it can take more time to upgrade database!! Also because of the change in device values​​, is the device informat...

@uAlex: Thanks for the PM, I cannot reply yet as I have not posted enough. Yes my code works - Initially it was failing when the lobyte evaluated to FF, by trial and error I found that if that is the case the checksum appears to be the hibyte instead. Since then all the messages received have calcu...

@romac: At the moment I bought the PowerMaster, i didn't know the report wasn't instant. I knew it worked with the PowerLink protocol (thanks to Wouter). I need to analyse the protocol a little bit more, maybe i can get more usefull information out of it (already months on my todo list ;-(). The Pow...

I have the PowerMaster 30 (UK) here and I am getting the motion sensor events now (you need to enable "always on" on the motion sensor first) via the serial. It isn't realtime, like the PowerMax. I get them once a minute. I initially had some timing issues in the code i am using, which som...

@Mario:

If you got issues, maybe you can share some code / examples where it goes wrong?

Op het forum is er een doorlopende 10% korting (15Domotica), dus je kan de set krijgen voor:

319,95 - 32,00 = 290 euro

Het was ooit 15% en zonder korting onder de 300 euro Ikzelf ben ook Z-Wave only nu.

There are 2 options given to calculate the checksum, the first one is always working. The following one is NOT : Other way to calculate the checksum: 1. Sum all the payload bytes in a word; 2. Subtract both high and low byte from FFFF; 3. Low byte contains the checksum. It should be: Other way to ca...

A RFXComTRX would do the trick:

And supports much more

It also continues when HomeSeer is off/shutdown?

I understood the zwave.me firmware has issues with communication, so can't be solved ;-(

You can install tcpdump as follows:
$ sudo apt-get install tcpdump

@mschut:

There can also be something "weird" in the xml response, can you make a tcpdump of the xml-rpc traffic and email it to me?

to make a tcpdump:

sudo tcpdump -i any -s 0 -w /var/tmp/xml.eth port 9009
