💬 Building a Raspberry Pi Gateway

Jean-Chris Ô-ô

Or NRF24L01+ and Rasp PI also as gateway/controller possible ???

hek

Yes, NRF24L01+ will also be supported.

Patrik Söderström

When do you think the install and build instructions will come up? :) Will this work with a B-model? (bought 2013)

hek

I'm not sure, @marceloaqno will finish the page when he feels the configuration options is stable enough.

breimann

Yes, can I use my Rasp Pi as a GW/Controller all in one? I have setup Domoticz on my Rasp Pi so could i do this and add an NRF??

alexsh1

RFM69 will work on RPi.
@marceloaqno PR works fine more me on my RPi3 so it will work on RPi2 or below, but this is still beta and has not been merged into development branch yet.
yes, it is possible to have 3-in-1 (nrf24l01+ RPi and Domoticz or any other combination).

frencho

I just saw that the PR537 was merged
@marceloaqno great job, do you now plan to write some build instructions ? I've had a look at the file, but I don't want to mess it all up

marceloaqno

@frencho I hope to write something this weekend, at least a draft.

GertSanders

@marceloaqno
looking forward to upgrading my gateway to v2 :-)

frencho

@marceloaqno just wondering because I could figure it out looking at your code : does it work with nrf24 And rfm69 or just nrf24?!

Regardless of your answer you did a great job, that awesome thanks

marceloaqno

@frencho thanks. Sorry no support for rfm69 yet. I order some rfm69 modules from ebay to play with but they haven't arrived. So I'm waiting to finish some tests.

hawk_2050

@marceloaqno I second @frencho's comment, excellent job on getting mainline support for the Raspberry Pi into the MySensors codebase. Thank you for your efforts.

Hello, I just installed @marceloaqno wonderful port of the mySensors 2.0 to the raspberry pi MyGatewaySerial. Thank you very much for that! I'm very glad to be using my boards that connect my radio directly to my Raspi! The installation went very smoothly.

I am having an issue with a few of my messages from my sensor node. My sensor node sends 6 messages. 3 are V-STATUS, 1 is V-TEMP, 1 is V-VAR1, and one is the battery voltage level. The V-TEMP and the 3 V-STATUS messages go through perfectly but the V-VAR1 and the Battery voltage are not reaching the Raspi. This is the output of the node:

@hawk_2050 same for you guys who helped, thank you for all the feedback.

@jerseyguy1996 I don't see anything wrong with your config.Try to add a small delay() after the first send() and before the sendBattery().

@annegerben This looks like a wire problem. I updated the guide, check the wire section again.

@marceloaqno thanks for the updated in the guide, I've now successfully connected the radio to the RPI.

Would it be possible to connect a I2C display to display some information, and drive that display from within mysGatway.cpp ?

marceloaqno

@ericvdb I2C is the next thing I'll do as soon as I finished adding support for signing.

@marceloaqno Amazing....adding the short delay fixed it! I'm curious why that is the case. Do you have an explanation for that?

marceloaqno

@jerseyguy1996 It's probaly related to this: https://www.mysensors.org/build/raspberry#improving-throughput-for-nrf24
