ESP8266 WiFi gateway port for MySensors

[Yveaux]

@Mickey I'm afraid it's not that simple... MySensors is purely written in C++, and although this code could be rewritten in C it is a lot of work and requires decent C/C++/MySensors knowledge.
Did you consider doing it the other way around and port your work to fit in this MySensors gateway?
Could be a lot less work (depending on how much code you wrote yourself) as C code compiles (almost) without problems in the Arduino IDE.

those esp projects I mention are very extensive to just port them.(mainly the httpd) but I once saw a guy here that made the mysensors code work on the native sdk ide but only wanted to sell the binaries and wouldn't share his code.

i have a few esp8266mod demo bords a node mcu 9.5 a few esp-01, when i get home i will throw a gateway together :) and test all you like ..i do not mind doing alpha or beta testing if needed ..great work btw ...

also has anyone used this beta .. looks very cool aswell :) http://www.esp8266.com/viewtopic.php?f=29&t=4540

kind regards
andy

@Mickey Maybe I don't really understand you application then... The web based configuration link points to a post about runnning gitlab, a local github. I dont get ít, sorry.
Running a webserver next to the gateway code shouldn't be a problem. The ESP has a lot of spare flash and the Arduino port supports a complete filesystem to read/write to it (see http://arduino.esp8266.com/versions/1.6.5-1044-g170995a/doc/reference.html, section "File system object (SPIFFS)")
What's to configure apart from SSID & password? This is just a gateway. Once online you can connect to it and stream all data to/from it using any client supporting the Ethernet gateway.

Thanks! Please join me in testing this code!

Nice, but as I stressed in my previous post this seems like overkill for a gateway to me.
Of course we can cram a lot of extra code and functionality in the ESP. It has a lot of power and someone might even build a whole home automation suite directly in it (anybody? ;-) )
Let's get this gateway usable, stable and tested. From there you can use it as a base for other applications.

ok i have used a esp8266mod dev board for my test hooked it up flashed the sketch and domoticz is seeing it ok and relaying my sensor data .. not a painfull process at all :) ..
will update tomorrow to see if it fails or goes fubar ..but so far so good :P)

[Yveaux]

@Andy-Pep Awesome! Good to hear its running without any troubles so far! :+1:
Maybe I frightened people by writing a too elaborate description how to set things up :dizzy_face:

[Andy Pep]

to me it was very easy to hook up and get working ..well done Yveaux you have given my collection of esp's a new life :) when my phone recharges ill take a pic and upload it ..i like the way it reboots when connection is lost .. handy feature :)

well done kudos to you :)

[DrJeff]

@Yveaux No you did not scare me away but I'm in loss of time to do this. I look forward to setting my esp gateway up in a week or so. :)

I wasn't aware of that. Most errors result in watchdog timeouts or access violations and cause a reboot. The Ethernet client has to be robust against this.
We need extensive testing to catch these kinds of errors and assure they are handled in a defined way.

A, damn ! Maybe next project then? :facepunch:

The problem lies mainly in the vast amount of ESP variants and how to wire them to be able to download and to connect the radio.

[Andy Pep]

ok.

ill put a serial interface on to it and keep it running for debug data ..ill post up the next 3 hours of data later on this evening ..

Sorry it was supposed to be "No you didn't scare", me auto correct!
I'm going to build this for sure!

I cannot replay this situation:

• Tried disabling my WiFI network on the router. Gateway keeps running and restores connection correctly when WiFI is enabled again. No reboot observed.
• Tried disconnecting telnet session. No reboot.

What did you do to cause a reboot?

[olof]

Yes great work is right. thank you

[Fabien]

Ok I will test it in few days.
Do you think is it possible to have an ESP gateway with RF24 and RF69 ? ESP have more memroy (ESP12E)

[Yveaux]

@Fabien connecting two radios should work, although MySensors does not natively support it.

Hi, let me ask a silly question just to confirm if I understand how this would work.

This gateway would receive Nodes data throght NRF or RF69 and then send it to controller via wifi? The way back would be, receiving controller commands/data via wifi and get to the nodes through NRF or RF69.

Is this right?

Thanks!

Correct!

Doesn't work here with stage version of ESP8266-Arduino (can't install stable version, I have checksum error). I use this module http://www.electrodragon.com/product/nodemcu-lua-amica-r2-esp8266-wifi-board/
Can't load at 9600 bauds (how can you change uplaod baud rate ?)
Crash on init and reboot :
