💬 Building a WiFi Gateway using ESP8266

[sghazagh]

Guys, just an update for my issue regarding Radio and my circuit.
The Radio was faulty, I received the new one, swapped it and all worked fine.

I just posted that here if someone want to use my last post image as a reference for connecting the Radio.
The wiring all are correct.

Thanks

Hi Hek,

Thanks for this guide... I have added an additional 433 RF receiver to my ESP8266 gateway. How can I send the data received from 433 RF to the my Home Assistant controller?

Hello, i have build a wifi gateway and use it in jeedom.
My gateway wifi as connection problem.
In jeedom, in the log of my sensors node I have almost every 2 days the message: diconnected from network gateway.
If I restart the node the communication is re-established.
Is this a problem with nrf24l01?

[derrij]

why esp8266 gateway shows only debug info?
when i comment //#define MY_DEBUG
where is no any serial output.

[mfalkvidd]

@derrij because it is a wifi gateway?

[AndreD]

If put in client mode
#define MY_CONTROLLER_IP_ADDRESS 192, 168, 2, 9
I get an error. How to win.

Hi,
Is it possible to use this setup without the nrf24l01 atached, so that i can use the esp8266 just as a sensor (not as a gateway)?

[mfalkvidd]

@Jonathan-Caes yes. Don't define MY_RADIO_NRF24 and you're good to go. It will still be a gateway, but a gateway with local sensors and no radio.

[joseyapor]

Hi how many Gateways Can i have on a network?

[mfalkvidd]

@joseyapor On one MySensors network there can only be one MySensors gateway. But on one IP network, there can be many MySensors gateways. Exactly how many depends on geography and chosen transports but at the very least a few hundred. Thousands if you really need and plan accordingly.

[alexalex]

Help! After connecting to the WIFI, I'm getting disconnected. Here's a log : https://goo.gl/fyr7ku

Any help in figuring this out would be appreaciated!

[mfalkvidd]

Welcome to the MySensors community @alexalex
The log is missing the first lines, but it looks like the microcontroller is unable to communicate with the radio. Which radio are you using?

See https://ci.mysensors.org/job/Verifiers/job/MySensors/branch/development/Doxygen_HTML/group__MyTransportgrp.html#details for more details about the log messages and https://forum.mysensors.org/topic/666/debug-faq-and-how-ask-for-help/ for the most common problems and how to fix them.

[Bogus Exception]

Is there a complete wiring table, diagram, or schematic? I have a working MyController/MySensors network on nRF24s, but I am adding WiFi with a ESP-201 module (white one with pins broken out for 2.54 pitch; see: http://smarpl.com/sites/default/files/images/ESP8266-ESP-201-pin-reference-v01.png)... TIA!

[mfalkvidd]

@Bogus-Exception did you see the instructions linked in the first post in this thread? You probably want the part that says "connect the radio".

[pihome]

if i reboot my wifi router mysensors wifi gateway wouldn't try to connect again, is this only with me or its common issue with wifi gateway?

[mfalkvidd]

@pihome said in 💬 Building a WiFi Gateway using ESP8266:

This question was transferred to a new thread by @pihome. Please don't answer here, to avoid double work and confusion.

Reporting batterypercent to Domoticz not working.
I have built a ESP8266 Gateway and I connecting a BME280 sensor. It report everything right with a serial gateway but with the new wifi gateway it not reciving the battery percent. I look in the serial monitor at the gateway and where is no battery data.

[Oleg Greengo]

Colleagues, tell me.
can I make it so that hosts register on the gateway only if I press a button on the gateway?

Perhaps there is an example?

[toozinger]

Hello,
I'm receiving the following errors:
warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

I have attempted to fix this problem through:
*Making sure I"m using the "NodeMCU" as my board in the Arduino IDE
*Trying different upload rates
*Pressing and holding the flash button while and/or right before upload

Hardware:
PC, windows 10
NodeMCU from eBay link above.

Any help? It appears others have had this problem as well, but I haven't (yet) been able to fix my issues through their threads.

Thanks!

Toozinger

...and how to connect Arduino & MySensors & ESP8266-01 (like this one: https://www.aliexpress.com/item/2015-New-version-1PCS-ESP8266-serial-WIFI-model-ESP-01-Authenticity-Guaranteed-Internet-of-things/32574207918.html?spm=a2g0s.9042311.0.0.ytiQMF ) with ESP 01 Serial Adapter - like this one (https://www.aliexpress.com/item/ESP8266-Serial-WiFi-Wireless-ESP-01-Adapter-Module-3-3V-5V-Compatible-For-Arduino/32740695540.html?spm=a2g0s.9042311.0.0.lSVdmZ), when i should use Tx and Rx signals only?
