Node w/o radio, direct to Vera & usb hub
-
I know that this has been asked before. I spend some time looking through the Forum and really couldn't find an answer. I have 2 relay switches that are sitting less than 6 inches from my serial Gateway and would like to see if there is a way to directly connect them to my Vera unit. My gateway, like most, is on a USB hub. I am not looking to add the relays to the Gateway I/O's, but would like to add a stand-alone relay that can be controlled directly through Vera. My search through the Forum has shown mixed results some people say it is possible others say it is not. I'm looking to see if anyone has actually successfully done this. I find my motion sensors and light sensors work great on the my sensors Network, however occasionally the two relays I have do not receive the signal to turn on or off from the gateway. I have found the serial Gateway sketch under the dev section on GitHub, but still was unable to make it work successfully. Any advice would be helpful.

@pbcstudios I don't have Vera. But I've experienced the simular problems in the best. Did you add the capacitor to the antenna? It solved my problem.
You could also try to add Ack mechanism to the sensor. I wouldn't attach the relays directly to Vera. If for some reason you want to switch to another HA. You'll have to find another solution.
-
Yes, capacitors, regulated wall wart, etc...lol. Doesn't happen often and it's not the driving force behind wanting a direct connect. It just seems silly to have a transmitter next to a receiver.
-
@pbcstudios maybe you can add a serial gateway and connect the relays to that. I agree, it seems silly to have a transceiver next to the gateway. I know some people have connected sensors to the gateway, but I don't think I'd do that.

@pbcstudios
The gateway in the development branch should be able to handle sensors/actuators directly connected to it (without the need for any attached radio).So what is the problem you're experiencing?
Did you create a sketch?

Thank you for your reply. While I can understand the node sketches and alter them to fit my needs, the gateway sketch eludes me. I took the GatewaySerial.ino sketch in the development branch and inserted voidsetup and voidloop from the relay sketch. I guess it's not as easy as combining node sketches. When I compile I get a "gw not declared in this scope" error. I'm not even sure if I do get it working, if I create a new Mysensors plugin and hit Start to include or create a Relay device in Vera.

I think you forgot to copy something. If I look at the Serial gateway example in 1.5.4 I see at least this line:
// Construct MySensors library (signer needed if MY_SIGNING_FEATURE is turned on in MyConfig.h) // To use LEDs blinking, uncomment WITH_LEDS_BLINKING in MyConfig.h #ifdef WITH_LEDS_BLINKING MySensor gw(transport, hw /*, signer*/, RADIO_RX_LED_PIN, RADIO_TX_LED_PIN, RADIO_ERROR_LED_PIN); #else MySensor gw(transport, hw /*, signer*/); #endifThis part (you need more) is missing in your sketch hence the errors.

Just a sec.. I'll modify the sketch a bit.
I have now disabled radio and the inclusion button feature and MY_LEDS_BLINKING_FEATURE as it will interfere with your relays.

@hek Thank you. I see how the pins are in conflict, but I copy the sketch posted and still got errors when compiling (ie. 'sendSketchInfo' was not declared in this scope). What am I doing wrong?
-
Did you really install the MySensors library from the dev-branch?
-
@hek Ahhh! Got it. Thank you. But can I use the original Gateway sketch with attached radio from the Master branch? My Serial gateway with a radio died this morning, which is why I started down this path. I figure if I have to start my Gateway from scratch I might as well try connecting my relays directly. Or do I have to re-install that library?
