emonTx is not powering up anymore

[Robert.Wall]

@TrystanLea will tell you. I do not have an ESP8266.

[TrystanLea]

@Robert.Wall

Or use the pre-compiled sketch that you (@TrystanLea) provided that I gave the link to.

I dont remember doing that, can you remind me of the forum post?

[Robert.Wall]

Umm…
I’m not surprised you don’t remember it, it was Glyn.

3-phase in Austria

@glyn.hudson has created a compiled version of the emonESP firmware for you: https://community.openenergymonitor.org/uploads/short-url/zegtvp5lICQT1w6J7ZoTXRnsiw3.bin You can load this into your emonESP and hopefully this will solve your problem.

@MarcioPaiva

Thanks, but a silly question… how to upload this .bin file into emonESP

I use Release 1.4.0 · esphome/esphome-flasher · GitHub to flash anything to ESP8266 devices.

[MarcioPaiva]

Thanks, borpin! But I’m receiving this error message:

Any ideas?

[borpin (Brian Orpin)]

Sorry no. It’s works on all the ESP8266 boards I used it on (although that is a windows platform )!

The other flashing tool I know of is this one GitHub - arendst/Tasmota: Alternative firmware for ESP8266 with easy configuration using webUI, OTA updates, automation using timers or rules, expandability and entirely local control over MQTT, HTTP, Serial or KNX. Full documentation at

[borpin (Brian Orpin)]

Ah, I have a feeling you have to do something to put those devices into boot mode.

[edit] yep GitHub - openenergymonitor/EmonESP: ESP8266 WIFI serial to emoncms link

[edit2] - can you not just do it OTA?

[MarcioPaiva]

Hi, thanks for your support! Yes, you were right, I needed to press and hold GPIO0 button and press reset: It enters on bootload mode and finally the upload worked. The problem now is that the emonESP_xxxx wifi network is up but it’s not possible to connect to it. I tried different devices and re flashed the the emonESP but no success… Any idea, please?

Thanks,

@MarcioPaiva

The problem now is that the emonESP_xxxx wifi network is up but it’s not possible to connect to it.

Any error messages?

@MarcioPaiva

Any idea, please?

Sorry not from me - @TrystanLea @glyn.hudson can you help?

[MarcioPaiva]

@borpin

Any error messages?

No. The device keeps trying to to connect forever… but no error messages…

[MarcioPaiva]

@borpin

Sorry not from me

No problem at all… Sorry for all the hassle…

[MarcioPaiva]

Everything seems to be ok…

[MarcioPaiva]

@borpin

The problem now is that the emonESP_xxxx wifi network is up but it’s not possible to connect to it.

@TrystanLea any idea, please? The bin file is not working…

[MarcioPaiva]

Hi,
I have an emonESP with a firmware set to 9600 baud rate because I have the 3-phase sketch on my EmonTx. When I try to connect to the emonESP for the first time to start the config, the device keeps trying to connect to the emonESP_xxxx network with no success:

I’ve tried other devices, I re-flashed a lot of times with different tools. The server is starting as you can see below:

But when I flash the emonESP with a firmware set to 115200 baud rate this problem does not happen.
I don’t know what else I could do.
Thanks,

[MarcioPaiva]

@Robert.Wall I have already compiled a new firmware with 9600 bps… same problem… and when I keep the 115200 bps it works…

[Robert.Wall]

@glyn.hudson
I pointed @MarcioPaiva towards your pre-compiled 9600 baud file for the ESP8266 - I think it’s that which won’t connect.

@MarcioPaiva
Can you try downloading the source file for your ESP and change the baud rate to 9600, compile and upload that?

[Robert.Wall]

It has worked in the past, for two users at least, I think.

We shall have to wait and see what Glyn says. I’m sorry you are having all this trouble.

[MarcioPaiva]

Thanks @Robert.Wall. Let’s wait.

[MarcioPaiva]

@Robert.Wall and @glyn.hudson I made it. I uploaded only the updated firmware and kept the SPIFFS. I don’t know how but now it finally worked. Now I’m studying how to setup the 3-phase sketch to Brazilian system
Thank you all for all the support!!
