Homeduino : connecting multiple arduino.

---

Hi,

i was wondering how i configure multiple arduino-s?
I would like to use relay-s and the inputs on the arduino-s,

what exactly do you want to do? without more information we cannot give appropriate support.
are you having several arduinos around the house or do you just need more i/o’s (then go for an arduino mega).

well, i want to use several arduino mega, because i need a lot of outputs/inputs.

So is it possible to use the homeduino plugin to connect multiple arduino mega?

The Raspberry Pi should give you a lot of inputs and outputs?
Can you give some real numbers and hardware about your project?

i don`t want to offend anyone, but is it possible with the homeduino plugin or not???

or is there another plugin that can handle multiple arduino`s ( my sensor gateway sketch with local relay/inputs / johnny five plugin with firmata)

I have arduino mega`s lying around, so i want to use those,

As far as I now: no, the homeduino plugin support only one arduino.
Again : No one can help you, without any further information.

You can easily attach local relays/inputs/sensors directly to the GPIO’s on the Pi and control them from Pimatic.

@koffienl said in Homeduino : connecting multiple arduino.:

As far as I now: no, the homeduino plugin support only one arduino.

that’s correct. pimatic can only handle one homeduino instance

if you need more io’s you maybe could try it with the johnny five plugin and port expanders

thanks for helping out, i am gonna try johnny five with mcp23017 i think.

Does anybody know how stable pimatic on rpi2 is? I mean what is the longest time it has run without failure or reboot?
I am testing this setup , because i want to migrate from domoticz to pimatic,
i like pimatic`s interface 10000 times better!!! and it is far more responsive and configurable.

well, how stable pimatic is running on any system depends on your system setup, connected hardware, lan/wlan stability and so on. guess it’s nothing else than with domoticz too.
my pimatic pi3 is running stable for almost 39 days now without issues. i am sure it even will be running longer without problems, but sometimes you need to reboot for any reason…

i was trying domoticz once and deleted it after some hours of trial. the interface is horrible

@djazzz
FYI
ofcourse it’s depending on your Hard-and Software and the complete setup of you installation but up to now my pimatic is running since a very long time without any issues preventing it from accessing my most important devices.

In my system there are a lot of different things:

• homeduino on Arduino with RXB6
  • a couple of 8 wall-plugs 433Mhz in and around my house.
  • 2 temp and hum sensors 433Mhz at west/east side.
  • original RF remotes switching something via pimatic rules
  • selfmade RGBW lighting for kitchen w. automated on/off/color scenes morning/eveng linghts …
• MAX! Plugin with 8 heating thermostats and a wall therm display.
• some ESP8266 Relay boards controlled via shell scripts.
• mySensors Plugin at Arduino-Nano serial gateway
  • with mesurement for FuelOil in the cellar tanks.
  • prepared some more sensors and relays for garage doors, but still not in real use.
• Get a couple of 6…8 values from central heating system via shellscripts and display in pimatic.
• Get values from photovoltaic generator via scripts reading it from PV-WebBox.
• iFrame displaying some Information from other servers
• Mail-Plugin sending me most important information
  …++ (PingPresence; WeatherForecast; Sunrise…; sysinfo …)

Sometimes I’m playing with it a couple of days but I remember other periods it was running for month! without any reboot, also not any touch of the system exept using it from GUI by my wife and children (e.g. when i was on business trips over some weeks).

For me this is alreday now very stable and not really beta software …

thanks for your replies,
i am doing an test to see how long the rpi2 with pimatic keeps running without problems,
if it survives 2 months, it ll suit my needs!

Raspberry Pi Model B+ , Raspbian Wheezy , Pimatic 0.8.102
Uptime : 99 days
Pimatic service runtime : 99 days

Plugins used (not listed are the obvious ones): DS18B20 , Homeduino , LCD, Mail , OpenWeather, SysInfo, Sunrise,

Running two pimatic servers now in parallel. Both implemented on Pi B+. Starting since 24-12-2014 with version 0.8.30. Now running one on 0.8.101 and one for test on 0.9.32 since a few days.

Both rocket stable with on this moment a minor date related bug.

Interfacing with homeduino, weather, mqtt, rest api, mysensors using also cron, shell execute, ping, dewpoint, pushover, iframe, location.

Switching more than 10 devices, reading sensors temp, hum, pir, p1 port of smart meter and reading solar panel data, combining this info and automate and securing my home.

Starting small but at this moment tons of rule to automate everything.

Interfacing through the rest api heavely with Esp8266 sensor, input and display devices.

Bugs are fixed quickly and the is an active support community to help you out.
