PROBLEM DESCRIPTION

A clear and concise description of what the problem is.

Hello, i try to send an email on high température into a script

all that is in my sonoff zigbee bridge, flashed with tasmota of course

so far, manage to print on high température and link it to a bulb, to be sure that i am going to the right place in the code

19:24:08.916 CMD: sendmail [::::*:mrpatate76@gmail.com:test sendmail] juste un test
19:24:08.918 mailsize: 44
19:24:08.919 smtp.gmail.com - 465 - mrpatate76@gmail.com - password
19:24:08.920 mrpatate76@gmail.com - mrpatate76@gmail.com - test sendmail - juste un test
19:24:08.921 Connecting: smtp.gmail.com on port 465
19:24:09.021 Connection failed
19:24:09.024 RSL: RESULT = {"Sendmail":"Wrong parameters"}

i test my password to be sure it is working ( in app paswaord) and it is ok, so i guess it is something in code or related to authentification on gmail side

i compile using tasmotiser including this
#ifndef USE_SCRIPT
#define USE_SCRIPT // adds about 17k flash size, variable ram size
#endif
#ifdef USE_RULES
#undef USE_RULES
#endif

#define DEBUG_EMAIL_PORT Serial

test my password to be sure it is working ( in app paswaord) and it is ok,

Are you using your Google account password ?
This will not work
You must create an "application specific password"
https://support.google.com/mail/answer/185833

barbudor · 2022-01-12T20:04:05Z

And you need to set the EMAIL_FROM with < and >

    #define USE_SENDMAIL
    #define EMAIL_USER "username"
    #define EMAIL_PASSWORD "xxxxxxxxxx"
    #define EMAIL_FROM "<username@gmail.com>"

i think it is a authentification or Secured Connection matter from gmail server

mrpatate76 · 2022-01-12T20:12:45Z

still the same with or without the <>

Did you followed the instruction for application specific password ?

It will NOT work with your Google Account password

mrpatate76 · 2022-01-12T20:14:25Z

yes got the 16 letters for application specific password. try it on my phone and worked, but same one in tasmota get wrong parameter, and send nothing since not activity is shown on my google account page

barbudor · 2022-01-12T20:42:01Z

Don't send to yourself, I think gmail is not supporting that
I'm recompiling a version with sendmail to test again as I haven't used that for months

mrpatate76 · 2022-01-12T20:50:53Z

oh, good to know, i will try to send it to my other email, juste to see if it work.

dont look like it change anything, let me know if you got it to work on your side

thanks for the help

barbudor · 2022-01-12T23:07:01Z

Can't get it to work, neither with gmail nor my local smtp server
Looks like something might be broken
will need more investigation

Alternatively an easy way to send an simple email is to use a WebHook with IFTTT or Integromat or Zappier that you can call from Tasmota using WebQuery command
You can also use Discord with a WebHook too

mrpatate76 · 2022-01-13T16:13:56Z

hello,
I set-up for WebQuery
i compile adding
#define USE_WEBSEND_RESPONSE
on ifttt, i manage to get it working for webhook, and my email, i can trigger online using
https://maker.ifttt.com/trigger/alarme/with/key/d1kz82kwUI0Tr8SThMsx1X
and this work, since i get email

but in tasmota console, when i try to do the WebQuery unsing:

WebQuery Https://maker.ifttt.com/trigger/alarme/with/key/d1kz82kwUI0Tr8SThMsx1X GET
i received : Host not found. As you can see below:

is there anything else that need to be compile to get it working?

thanks again for your help

17:12:02.846 CMD: WebQuery Https://maker.ifttt.com/trigger/alarme/with/key/d1kz82kwUI0Tr8SThMsx1X GET

mrpatate76 · 2022-01-13T16:20:18Z

got two alarm mail from ifttt

barbudor · 2022-01-13T18:16:59Z

You just got mail another mail :)
I suggest you delete you IFTTT action and recreate it with another token if you don't want to receive alerts from jokers of my kind or worst

17:58:50.347 CMD: webquery https://maker.ifttt.com/trigger/alarme/with/key/*****************   GET

gemu2015 · 2022-01-14T07:56:57Z

ok tested email on esp32 and esp8266. (both use very different approaches)

esp32 works without any problems.
keep in mind that emails must not be enclosed in sharp brackets here while in esp8266 it has to be

esp8266 indeed does no longer connect to gmail in the latest dev version. however at least in an older version (9.4) it works well. so it cannot be due to change at gmail.
since nothing has changed within email driver itself some changes in light_bear_ssl or core must cause this failure.
will take some time to evaluate this issue.

gemu2015 · 2022-01-14T08:22:41Z

it turns out that light_bear is the cause. taking the ssl lib from 9.4 into latest dev solves the problem.
@s-hadinger may be you can determine what causes failure in SMPT for ESP8266

gemu2015 · 2022-01-14T08:49:17Z

found the reason and fixed the issue. will do a pr later today

s-hadinger · 2022-01-14T11:39:52Z

Thanks @gemu2015 I'm curious what was the problem?

gemu2015 · 2022-01-14T11:48:00Z

simple esp8266 smtp needs insecure TLS. the new default was insecure set to false.
i simply introduced a set insecure call like in standard TLS.

barbudor · 2022-01-14T15:27:18Z

Thanks @gemu2015

barbudor · 2022-01-14T19:44:18Z

Which tasmota are you compiling ? "tasmota.bin" ?
When customizing you must compile "tasmota" and not any variant (such as tasmota-sensors or other)

mrpatate76 · 2022-01-14T20:01:00Z

i use tasmotizer for sonoff zigbee bridge, and passing custum parameters

mrpatate76 · 2022-01-14T20:04:06Z

by the way, i manage to get an email using

=>WebSend [maker.ifttt.com] /trigger/alarme/with/key/d1kz82kwUI0Tr8SThMsx1X

barbudor · 2022-01-14T20:04:49Z

Tasmotizer is a PC app to flash firmware. It's not a compiler.

Are you talking about TasmoCompiler ?

mrpatate76 · 2022-01-14T20:25:31Z

sorry you are right
tasmocompiler

ESP8266 with onOff Zigbee Bridge
option for
Light sensors
Temp/Hum sensors
Timers
Display Vcc
Web interface
Script

#ifndef USE_SCRIPT
#define USE_SCRIPT // adds about 17k flash size, variable ram size
#endif

custom parameters:
#define USE_WEBSEND_RESPONSE
#define SCRIPT_POWER_SECTION
#define USE_SENDMAIL

Jason2866 · 2022-01-15T11:04:06Z

ALWAYS use Tasmota as base for self compile. Other env are specialized and restricted.

gemu2015 · 2022-01-21T11:04:20Z

@mrpatate76
i now also get this compile error (didn't have this before)
try enabling TLS together with USE_SENDMAIL
#define USE_TLS
#define USE_SENDMAIL

Tino4 · 2022-01-29T09:58:59Z

@gemu2015 , hi sir can you tell me sendmail is working at the moment ? I've tried almost everything and still not working.I have changed the 3 files and i added the rule #define TLS in config override file ,still not working when i type the command =>sendmail.... in the console , can you give me advice / info ? Thank you very much in advance.Grtz

gemu2015 · 2022-01-29T10:29:50Z

@Tino4

use the very last dev Version.
#define USE_SENDMAIL should be enough now

and try the full cmd in console (with your own credentials and email addresses)

=>sendmail [smtp.gmail.com:465:user:password:<from@gmail.com>:<to@gmail.com>:test]Hello world

gemu2015 · 2022-01-29T10:31:40Z

you must use the sharp clips on esp8266 (not on esp32)

Hello
I am new to smart home. I am learning tasmota and I like it very much. Recently I learned to compile correctly. I need help setting up for sending to icloud mail. Of course, I have already tried with the application password but it does not work.

gemu2015 · 2022-02-08T06:55:19Z

the mail option in esp8266 is very limited. it does only work with a few mail servers and only with setting the email server to reduced security. (gmail is working, icloud does not)
the esp32 mailer supports all kinds of email servers, i assume also icloud will work.

Tino4 · 2022-04-16T10:50:29Z

Hi guys , i've still a problem with sendmail esp8266 , always the first time execution troubles with the sendmail command , second ,third .....time no problem at all.it seems that if the esp8266 is inactive for a while the problem occurs.I've disabled sleep ....no solution.I've tried last firmware version ...no solution.Anyone a suggestion?P.S. there is also a bug in the calculation of the ISL28022 , the ISL28022 uses a 5 milliohm resistor instead of an 100milliohm and the isl28022 calculation is based on a ina219 thus wrong current value , also the bus voltage calculation is wrong.Maybe someone can give me info or can help me with these.Best regards , Tino

Hi all,

trying to send email with ESP32-CAM image as atachment with the Tasmota script. Sending email through Gmail (16character app password procedure) works. But the ">m" section is not evaluated, also i have to fill in the values at the sendmail line, "*" are not parsed either ...

I use the tasmocompiler for my firmware and trying to find the missing part.

My defines are a stacked up set of includes found in a lot different solutions from the web (so it is a mesh ;-) )
#define USE_WEBCAM
#define USE_SCRIPT
#define UFSYS_SIZE 8192
#define USE_FEXTRACT
#define USE_SCRIPT_WEB_DISPLAY
#define USE_SCRIPT_JSON_EXPORT
#define USE_SENDMAIL //Not sure if this adds something foor ESP32 CAM
#define USE_ESP32MAIL
#define USE_TLS
#define DEBUG_EMAIL_PORT
#define SDCARD_DIR //Not essential I think
#define USE_SCRIPT_FATFS_EXT //Not essential I think
#define USE_SCRIPT_FATFS //Not essential I think
#define USE_UFILESYS
#define USE_SDCARD
#define SUPPORT_MQTT_EVENT //new

can anybody tell me the missing "define" ?

the "*" body can not have a in front of it .. the >m section is now evaluated .. :-)))
