Custom made ethernet gateway based on atmega128

[axillent]

I got an idea to improve my gateway by adding 433MHz receiver
I'm succeeded by adding it into the same dimension

As discussed with @hek it will be other version of EthernetGateway sketch able to handle both NRF24 and RF433 reciever

Just a small change to schematic

@epierre About security within rf24 we are close. I have implemented and verified HMAC-SHA256 signing. I just need some more time to implement support for a pure software-alternative to the ATSHA204 as well and my "offering" will be complete. Check the security thread (I will post my update there once finished).

[epierre]

@Anticimex This is good news, that would make us a bit safer... next step will be two ways SSL encryption ;-)

[Anticimex]

@epierre ha! Well, whoever wants encryption, feel free to do it :) I see no need so I'm skipping that though. I am fine with somebody potentially reading the sensor values and instructions I transmit. What concerns me is if somebody could fool my system and inject their own commands. But with my signing, I challenge anybody to try ;) (and I publish full sources)

I made a version with RF433 receiver, I'm able to fit it into the same size PCB & same size box

will work on the new code to support RF433 sensors. The idea is to use ID=254 for the single node which will holds all RF433 sensors as it's children. I will need to manage a special inclusion for RF433 sensors. I have two buttons and 3 leds. This probably will be used to select & indicate sensor type during inclusion. Sensor type and child ID will be stored in gateway EEPROM. For the controller sensors will behave as regular motions / fire / door / water leakage / etc. sensors

I have all this sensors connected to simple GSM alarm system. The advantage to connect the, to mysensors is a reuse. All sensors will be working simultaneously with alarm and mysensors

@axillent Were did you get those screw inserts?

all were purchased on aliexpress

@axillent Would you happen to have links?

[axillent]

@ServiceXp sure

@axillent Thanks..

hey axillent,

Could you upload the source code of your gateway?
You use another slave that?(Type of This gateway send a RF to anther module and control de lamp?)
If Yes could you post the schema and de souce code?
Thx

[axillent]

@DanielD sorry, did not get your question
my gateways are using standard ethernet gateway sketch

[DanielD]

Hmm, you use the ethernet gateway sketch:),

Okay,I will do the question again, because it was a bit confusing.

This getway control another things? For exemple "Smart Plug" Module?
If yes, how you control this Plug?

Thx

[axillent]

@DanielD my gateways are not doing other things for now

i have two issues with my gateways 1. it is hard to manage multi-gateway network, you need to use hardcode 2. NRF24 is not the single network I plan to integrate to mysensors

there is an idea to redo class structure of the MS library to create a simple way of embedding drivers other than NRF24
as soon as this will be developed we can do a new driver for RF433

the idea on how to integrate RF433 is simple, bud without class restructuring it will be a deep hardcode

[DanielD]

Okay, I understand
Sorry my silliness, but what do you mean hardcore 2?
I will do this sketch today(Ethernet Getway), but my big problem will do sync the getway to this sensor(Plug) or another sensor and control via web/cellphone
:/

[DanielD]

This post is deleted!

[DanielD]

@axillent
You modified the code base, alright?
Could you send me the new code?
Thx

[axillent]

@DanielD 2 is stands for the second issue )

before class restructure I will recommend you to use sensor sketch as a gate between RF433 and mysensors

[DanielD]

@axillent
Okay, I will try :)
The sketch of the Plug, I will see that do many challenges, but let's go.
I was reading the code the Ethernet getway, but i learn how i sync it with another sensor.

Thx for your help
