I would like to ask for an advice in choosing controller/platform for my project. Basically what I want to do is RPI local server with web server, where I can display data from arduino sensors and from web page (web server) I need to be able send values to arduino (like temperature... arduino will manage everything else). The connection should be serial (usb) as I don't want to use any shields.

Do you have some recommendation of controller/platform? Is there some simple tutorial for this case?

I tried to use Home Assistant, but in the end I couldn't pass data from web to arduino. Second one, which I tried was Blynk... but I couldn't even connect the arduino to the RPI...

Do you have any advice on these? PIdome, myController, myHouse, Ago Control.

I'm using Arduino MEGA and RP-3

  • You forgot OpenHAB – Jaromanda X Oct 31 '18 at 2:28
  • I couldn't pass data from web to arduino - so how can you pass data to arduino? – Jaromanda X Oct 31 '18 at 2:29
  • @JaromandaX Sorry, I didn't explain my problem correctly. It should be better now. Do you think that OpenHAB can handle this communication? – Blank Oct 31 '18 at 6:44
  • Why do you want to connect your devices to the RPI via USB/Serial? Why not pass data from the arduino sensors using MQTT or similar? – jaolstad Oct 31 '18 at 14:10
  • @jaolstad I don't want to buy additional shields for arduino. USB is the simplest and easiest connection to make or do you have some advice in using different interface? – Blank Oct 31 '18 at 17:58

You can also have a look on Domoticz which provide support for a lot of interfaces

To collect data from remote sensors, in place of arduino you can have a look on ESPeasy which is free. It is based on an ESP8266 which is very cheap and connects to Wifi (see Wemos modules on ebay). It supports a lot of sensors and can use https or mqtt messages to domoticz or to others
