I have the same problem from three days.
MySensors plugin : Cannot send command - communications error
but MYSController 1.0beta is running ok, pinging to gateway is ok. I cant' understand what is happened
@Marshall It's always great to hear from people that their problems are solved. And it's also great that you were able to solve it on your own!
I actually think that most things you'd wanna create are available through the build page.
Since it's a pity to have one Arduino per sensors, the next step would be to try to combine some sketches. I mean Arduino's are relatively cheap. But if you use only 50% of their capabilities and would use another for another sensors, it will end up being more expensive than needed.
@yoram apart from all the "2016-08-08 20:12:50 Message" texts (does your terminal program add them?) output looks OK.
I don't have a Vera, so can't help you any further...
I had the same problem after updating to UI7 from UI5. Finally I was able to reset the box with this help with SSH (using putty on windows) : http://forum.micasaverde.com/index.php?topic=9949.0
After reset I upgraded the firmware to latest one and then take the settings from saved backup.
It kind of works now, but I am still struggling to get MySensors Plugin updated.
If anyone has any ideas, please reply in this thread: https://forum.mysensors.org/topic/4226/changing-baudrate-to-57600-in-veraui7
@leeoz please do not post the same question multiple times. It wastes people's time.
No roadmap for the Vera plugin at the moment. I_HEARTBEAT will be documented on the main site when 2.0 is released.
@BartE has done a great job implementing new sensor types on Vera. Creating a new sensor type is a fun and pretty isolated development task. Additional maintainers is always welcome.
I don't know which sketch you're using, but sure you should be able to control send frequency in the program (hard coded).
There's also a possibility to request values from a senor from Vera (using lua code). But it means your sensor needs to be awake all the time and answer these requests. Basically you have to setup a function which listens to incoming messages from controller and answers them. Like the RelayAcutator example.
