General Discussion

Not at the moment. There is still only a few boards where the author has activated sales function. When this number grows, I'll add some more filters. https://www.openhardware.io/explore#view=forSale

@dzairo search the Web for rebooting arduino from code. There are many ways each with its own (dis) advantages.

You only need to enable if if you actually use the resulting ack message for something. If you look at the RelayWithButton example you can see an example of how the local relay only get updated when the ack is received (after pressing the local button).

Not sure I'm doing this right way, but changing this line: fh => $serialDevice->{'HANDLE'}, to this line fh => new_from_fd IO::Handle ($serialDevice->{FD}, "w"), Fixed Filehandle GEN0 opened only for input bug for me on RPi 2. Fix works because of $serialDevice->{'HANDLE'} is opened as read only in SerialDevice and should not be used for write: # a handle object for ioctls: read-only ok $self->{HANDLE} = new_from_fd IO::Handle ($self->{FD}, "r");

@mfalkvidd Thanks. That explains it all pretty perfectly.

I've got a MQTTClientGateway using an Uno with DHT22 sensor attached. It's working for weeks without problems.

@bjacobse RF circuit is mine, based on many simulations etc., so I can't fall back on 3rd party designs. Yes, it will have to be certified globally, as much as possible. I've been involved with the approval cycle in the past, so I'm familiar with how this works. I'm too old for financial involvements with other people, so I'll just have to see what "shakes out". I'm "beating the bushes" now for potential manufacturers who may want to procure the design outright. Thanks for your input.

Thanks.. I did break down and order 10 of the nrf radios last night... should be here tomorrow.. In thinking it through more, it seems that it's shortsighted of me to want everything on Wifi just because it's familiar.. I'd end up needing eventually to possibly expand my subnet, have to be reliant on an access point that is probably being killed by my son playing online games, etc.. I'm sure there's a learning curve to the NRFs, but from what I read about their low power requirements and the advantage of all of the self healing, it seems it's the right way to go.. Thanks for the info!

Found it! Thanks a million!

No worries. There is a reason it is called FAQ - lots of people ask that question :-)

Great that it worked. Thanks for reporting the result :)

Hi. I know this topic is a few months old now, but I'm wondering if you were able to accomplish what you wanted to do. I have a wifi gateway set up and would like to do something similar but with Home Genie as the broker running on a Raspberry PI. Did you have to modify the MQTT Client code much to fit your needs? I'm new to MySensors, but I've been researching topics as much as possible before I dive into the code. Can you point me to the version of the client code that worked for you? I would appreciate any help or tips as I am eager to set up several sensors around the house and perhaps a relay to control a garage door. Thanks.

Ok got it working. But now i see the main problem. When you change the colour - there is a lag so othe colours are seen. Same goes to switching off. For example we were at white light fullbrightness than switched off. You can first see the light becoming yelow, than blue than off. How can this be fixed? If i understand correctly - you have to pass all these HSB value processing to arduino and have the controller send 3 values at once. Are there any examples?

oh it's really long .. thanks.

It would be cool to be able to do the other way around... have wifi/bluetooth recievers listen and determine when someone was nearby. This could be used without the need for any application installed on your phone. Anyone have any pointers for a system like that? I know we use it in stores for example to measure visitors and how they move within stores/malls.

It's enabled automatically for the w5100 gateway.

@scalz Unfortunately, I didn't like the chipquick flux performance as much, so I reverted back to what I had been using.

[image: 1462873937252-water-pressuresensor.png] Update: I figured out how to make a few changes to the Vera device display. Now for some reason all three are reading from one analog pin. I have each one of them set on A0, A1, A2. Never mind as I was writing this post I think I figured out what I done wrong. For some reason I had the A0 pin defined twice in my sketch. Still need to test it an see that's the problem. And the only thing I have left to try an figure out is in the Vera Scenes the language is still in French. Anybody have any ideas how I can fix this??
