RECV REQ VAR1
Nice, looking forward to it! Let us know if we can help in any way
in case its down for whatever reason
A new beta is building at the moment (will take at least 15 minutes), please let us know if you got it working !

Is it still actual guidance to get USB based SerialGateway properly set up and recognized at Domoticz?hansrune wrote:For the connection question : Connection is to the Arduino via a serial USB interface.
As for RFXcom devices, it is convenient to make a persistent device name that Domoticz can read and write also for the MySensors gateway connection. Use the lsusb command to display the vendor and product id, then use these as in the following udev rule example.
Here is my /etc/udev/rules.d/71-mysensors.rules. Domoticz will find the Mysensors serial gateway via ttyUSB31

Maybe your right, I'll check on mysensors sources later.gizmocuz wrote:The acknowledge should be send by the gateway and not by the controller (software application) or did I miss something?
.So I checked and you are totally rightfets wrote:I'll check on mysensors sources later.
No, my patch is necessary to manage incoming message with ack request (we agree that the answer was sent abck by gateway).gizmocuz wrote:Does this mean all should work fine without your patch?
notify to who or how ?andriej wrote:And it would be also nice to notify that incoming message from MySensors is with ACK.

no...There are errors in the serial monitor when i ulpoad from the Codebender Browser PluginMediacj wrote:What is displayed in the serial monitor of one of your sensors? Do you see errors or?
