mysGateway: TSF:MSG:READ,0-0-0,s=0,c=0,t=0,pt=0,l=0,sg=0:
mysGateway: !TSF:MSG:LEN,0!=7

looks like a power issue with the nrf24 module.

Ok,

I've tested with the Voltmeter and the NRF24L01 module do get a steady 3.26 V. Both the gateway module and the Arduino sensor node...

Im now building a few extra sensor nodes, so I can test without the Raspberry pi. Hopefully I can atleast get them talking based on Arduinos first. Before testing the Raspberry Pi.

Can I attach one or more DallasTemp sensors on the Raspberry Pi gateway?

I haven't seen anyone doing anything similar so it might require some work. But almost anything is possible given enough work :)

[jerseyguy1996]

Has anyone else had an issue with getting a sensor node to reconnect after a lost connection? I can see it attempting to reconnect but even though it is back within range of the gateway it won't reestablish the connection. If I reset the node it re-establishes the connection without any problem. This is the cycle that it gets stuck in:

@Christian-Simonsen multimeter will not detect issues with the power feed (noise or unstable). It just says that you voltage under zero load is 3.3V.

Appears things are changing, please update wiki:
Warning: --my-radio is deprecated, please use --my-transport

[Patrik Söderström]

@mfalkvidd Alright :) The thing is that I have my Raspberry Pi as a Gateway today near my server rack and would like to measure the temperatur. Maybe I just get a Nano to do the work for me. Just would have been great to use the Raspberry.

[mfalkvidd]

@Patrik-Söderström You can probably connect a temperature sensor to the gpio pins and have your controller read the sensor (without using MySensors)

[marceloaqno]

@carlyler Thanks for pointing that out.

[marceloaqno]

@jerseyguy1996 Are you using a decoupling capacitor?

[jerseyguy1996]

@marceloaqno Yes its 220 uF. It was all I had handy. I read somewhere that this may be a problem specific to the arduino nano. I may give it a try with the pro mini. Although I'm not sure what that may have to do with it.

Edit: I tried the same sketch on an arduino pro mini and it worked fine. When I simulated a loss of connection by walking out of range of the gateway it immediately reestablished the connection when I got back within range. The only difference is that the pro mini is running at 8 mhz whereas the nano runs at 16 mhz. Not sure how that affects things.

Hello everyone. Is there a way to reduce the number of Heartbeat messages the gateway produces by itself? Using MYSController to analyze the data traffic, I see every 10 seconds a Heartbeat - would like to reduce this once everything is working as expected to maybe every 5 or 10 minutes...

[hek]

@Velo17

Just sleep longer. It sends one heartbeat every time the node wakes up.

[dopeeye]

@Christian-Simonsen

I have exactly the same error

mysGateway: !TSF:MSG:LEN,0!=7

Have you been able to resolve that problem yet? I have tried multiple radios with different capacitors and powersources grounded to the Raspberry Pi.

thanks

[Christian Simonsen]

@dopeeye

Sadly not. I ended up creating an serial gateway (arduino with NRF24L01 and a USB connector) and connected this to the Raspberry Pi, rather than connecting the NRF24L01 directly to the GPIO pins. This worked perfectly straight away.

[dopeeye]

@Christian-Simonsen

Too stubborn to give up, yet.
If i find a resolution I will let you know

[Graham]

I would like to try this, but my pins19-23 are already used by other hardware. Has anyone tried using the SPI1 Pins?

[carlyler]

@dopeeye I had this issue and unfortunately changed several things at once and got rid of it. However, one thing I noticed was I had different versions of mySensors in my library directory since I downloaded the examples package. Therefore the sensor was likely compiling on a different version than the Gateway. You might want to check that.

If you could post more of your logs (sensor and gateway) it might help.

@marceloaqno

When running as a service, is there a way to watch the debug log?

[Patrik Söderström]

Any ETA on support for RFM69 ? Need to extend my coverage :)

[alesc]

Done:

1. git clone https://github.com/mysensors/MySensors.git
2. ./configure --my-gateway=mqtt --my-controller-ip-address=127.0.0.1 --my-mqtt-publish-topic-prefix=mysensors-out --my-mqtt-subscribe-topic-prefix=mysensors-in --my-mqtt-client-id=mygateway1
3. make.
   Got error:
