Re: Total Noob to mysensors Looking at feasibility of a project

I came across this topic which is a bit old... it's touching on the idea I've had for a Mysensors Single mobile network.

The idea is this:
Basically I'd like to create a network that I can move around in say the outdoors when camping, or out in the bush (yes, Im in australia) with the kids, where you can set in place several outdoor nodes (battery operated of course) maybe some with motion sensors and alarms in them, then maybe a pair of laser trip wires etc. Then you have a controller/gateway in one that is mobile either using an old smartphone that jumps on a small point to point wifi network, or uses bluetooth to talk back to the main controller, or maybe just a controller / gateway in one with a touchscreen??

Then you can monitor the various sensors - eg. if a motion detector goes off, you know which one, and you can reset or tell it to sound it's alarm or reset the alarm all from the control node/controller.

Obviously these would be all within 50-100 metres.

You might have a lux sensor to know if it's dark or light, then you could turn on some light nodes if someone trips your "perimeter" etc.

This could have some great application for group games for kids, (or kids at heart) or some more serious implications with detecting animal / foxes / etc entering a zone or area you're camping in etc.

Am I making myself clear? Does this make sense what I would like to do?

Do you think it would be feasible with mysensors (i think so) and if so, what would be the most simplest solution to develop it?

Ie could you just use a bunch of nodes talking back to a node that has the touchscreen without a gateway and controller???

I've created my own network at home, using a RPi running Domoticz, an arduino gateway with an NRF24, and various nodes.

I just wanted to see about setting such a network up that is fully mobile, maybe not internet connected, but maybe in future might be with a GSM card or similar??

Just a thought, and wanting to seek more experienced Mysensor members input on the matter, or if someone else has had the idea already and started implementation??

@nikil511 and @Lendog I got it going to some extent, here's the serial monitor dump from the NodeMCU. I'm not sure what's happening, but it seems after a certain number of tries it dies, and won't reconnect to the wifi.

Any ideas?

@nikil511 thankyou. I don't think redoing from scratch is an option, so i'll try your code. Thankyou @Lendog as well for taking the time to reply. I'll see how i go!

@Lendog Hi there, i'm trying to get @nikil511 esp8266 gw controller & node going, but having all sorts of issues compiling the code in the Arduino IDE. Do you think you could help me as you got yours going last year?? I haven't had a reply from @nikil511 so far.

Hi @nikil511 great project... just wondering how difficult it would be to add an OLED to show the (local) temp and hum on the sensor node with your pro mini + NRF?
The reason I ask is i'm looking to create a little setup for a friend who works for a charity. They run a community garden for refugees, and have just built a hot house (from funds raised in the community).
They would like to monitor the temp and hum (and possibly control the shutters in future) of the hot house but also be able to send the data to the coordinator's mobile phone to remote monitor.
This project came up when i was searching.
It just would be helpful to display the local Temp and Hum in the hot house for them also when they or any other volunteers are in there.
Thankyou!

@Boots33 Excellent. Thankyou.

@Boots33 Nice. Good thinking re the wedge. I was thinking some sort of angle type thingy to level it.

Just a question re your power supply. Once you got the node onto the 9v plug pack, did you find the sensor was ok being supplied with 5v from your Nano?

@Boots33 I've been collecting some of the parts for this project. Just wanted to check something. I have a similar poly tank like yours, but is there an issue with mounting the transducer so it's not completely level as the roof slopes up?? Do you get what i mean?

@dpressle Nice job!

@dpcr thankyou for this explanation. Quite clear.

Yes, i've installed Domoticz on my pi3 fine. It's been running for 6 months on there quite well.

I've setup a static IP address on my local network.

It's the OPENVPN connection that's the issue i think.

Thanks though. Very helpful.
