Thanks guys, will implement these and see how it goes

Thanks guys. Will jump in and see what happens.

Hi all,

Just wondering if it is OK to have two gateways running within range of each other. I have a home system running, but want to build a system for a friend and do the testing at home. That means I will have two gateways (and their nodes) within range of each other when doing the test and build.

I would imagine both gateways will pickup all nodes. Would this cause confusion in the systems?

Thanks for the advice

@jkandasa as discussed on chat, but thought I would put the info her as well.

Using one of the 4 USB ports on the PI.

Versions

Linux raspberrypi 4.1.6-v7+ #810 SMP PREEMPT Tue Aug 18 15:32:12 BST 2015 armv7l GNU/Linux

@jkandasa I do have an AMA0, but it does not work on that one either. The gateway is definitely connected to ACM0. Which is the one it works on when I have Domoticz connected up.

Something odd is happening with the PI USB side of things. Tried switching to another port but no luck there either.

As a side, I installed on windows and it works fine, so I know the gateway is OK, but I really want it running on the PI at some point

@jkandasa Checked my settings and they were already set as per that article, so I don't believe that is the trouble I am facing. From the logs I sent you, anything else you think could be causing the issue. Was the port being opened OK in the system?

@jkandasa OK thanks

At least I am not going crazy :)

@davidbd Thanks for the reply.

Yep, can connect to the port and see the node / gateway data in the line.

Still nothing though in the Mycontroller

All my settings seem pretty standard, so not sure what the issue would be or what to check next.

@jkandasa Thanks

Have now done all that. Stopped the Domoticz server, started Mycontroller. I get the webpage up now, but still no nodes showing up and for some reason nothing is being written to my logs the past few hours at all.

What can I look at?

@jkandasa Thanks for that.

The latest Java version has go me going as far as server access goes, but I am having issues opening the serial port it seems.

I am trying to run in parallel with Domoticz, but I maybe having an issue trying to access the same port I am guess.

Suggestions on how to get around that?

For some reason cannot seem to get it running.

Have installed the software and the server appears to start, but there is no web access and this is what I get when I check the log.

Have I setup something incorrect

Just wondering if it is possible to run two controllers side by side both looking at the same serial port?

i.e. can I run Domoticz and MyController at the same time in serial mode with the one gateway or would it cause issues?

I have a requirement where I will be running a sensor in a remote location that I will not have physical access to for several weeks. I will have remote access via either port forwarding on the remote network or using weaved on the PI.

http://www.weaved.com/in-action/weaved-iot-kit

The issue I have is that from time to time, a node may lock-up and stop communicating (often due to a noisy electrical environment). While it is not a common thing, I cannot afford to lose comms with the node, so I am after a way to either

1. have the node reboot at some specific time or some type of watchdog system on board to do this

2. a way to reboot the node remotely when I see it not responding anymore

Any suggestions, tips and pointers appreciated. If I had to change controller for this specific project I could consider that, but must have the remote access.

Setup

Raspberry PI
Serial Gateway
Moisture Detection Sensor
NRF24 Radio
Domoticz Controller
Weaved (http ssh access)

Thanks for the input all

I might put two sensors together and see what transpires to see if I can narrow things down a bit and see if it is specifically a sensor issue or the controller.

@BartE Thanks for that. My issue ended up being with the signal lead from the sensor to the arduino. A bad connector. Your advice on the pull-up resistor was very useful.

Thanks

Hi all,

Just looking for some help here. I have uploaded the soil moisture sensor sketch, but when I look on the serial port, it is just a constant stream of messages alternating as below. Eventually the system fails.

Even if if I disconnect the moisture sensor from the system it does the same thing, so not the sensor. If I upload a different sketch to the node (Dallas temp sensor for example) it does not have the issue, so I am thinking it is something in the moisture sensor sketch.

Any suggestions on what is happening?

Below are the messages that stream past in the serial monitor at high speed

send: 1-1-0-0 s=0,c=1,t=16,pt=2,l=2,sg=0,st=ok:1
1
send: 1-1-0-0 s=0,c=1,t=16,pt=2,l=2,sg=0,st=ok:0
0
send: 1-1-0-0 s=0,c=1,t=16,pt=2,l=2,sg=0,st=ok:1
1
send: 1-1-0-0 s=0,c=1,t=16,pt=2,l=2,sg=0,st=ok:0
0
send: 1-1-0-0 s=0,c=1,t=16,pt=2,l=2,sg=0,st=ok:1
1

This is the standard sketch i am using

Hi all,

Not sure if this a domoticz or mysensor issue. Every once in a while I will get a random temp reading on my graph and I am not sure exactly how to go about tracking down the issue, so any advice appreciated. The sensor being used is a DS18B20 on a serial gateway to a PI. Normally if I lose radio connection the sensor data will flatline so the issue must be somewhere else. In this case it has dropped to zero degrees.

@kolaf I was wondering what you needed to do to get MQTT working with the MySensors and Domoticz. Can you point me in the right direction for that?

Thanks, I will watch out for conflicting node id's

I have two gateways (home & work) and I am wanting to swap some sensors back and forth between gateways.

Is there any issue in moving sensors between gateways?

Once the sensor ID is assigned by the first gateway, does it then keep that ID when moved to the second gateway or will the second gateway try and assign a new ID?
