sending email in dzvents script does not work

[guenniac]

Hi,

I'd like to send email notifications out of dzvents scripts, but that doesn't work.

I have setup an email server in Setup -> Settings -> Email. Testing from there works and both email addresses receive email.
But from dzvents nothing happens.

Example:
dz.email('SetHeatingLow', 'set all thermostats to 10°C', '[email protected]')

Debug Log:
2021-12-28 17:26:59.350 Status: dzVents: Debug: - SendEmail = SetHeatingLow#set all thermostats to 10°C#[email protected]

No more info found.

Advice is needed!

Thanks

Isn't there really nobody with an idea?
Any hints are really appreciated!

Probably it misses at the end : “, dz.data.mailTo”

Meanwhile I have tested with this setting:

Code: Select all

	data = {
	    mailTo = { initial = 'root@sau' }
	},
....
        dz.log(logtext)
        dz.email('message from your lockRS script', logtext, dz.data.mailTo)			-- this does not work
        os.execute("echo '" .. logtext .. "' | mailx -s 'domoticz message' " .. dz.data.mailTo)	-- this works

The log shows:
2022-01-06 22:13:44.070 Status: dzVents: Info: lockRS: ------ Start internal script: lockRS: Device: "RS Stop (Virtual)", Index: 377
2022-01-06 22:13:44.071 Status: dzVents: Info: lockRS: RS Timeout - reset by manual action
2022-01-06 22:13:44.209 Status: dzVents: Info: lockRS: ------ Finished lockRS

I have no clue why dz.email does not work, while os.execute works!

Could someone look at it, if you need more infos, please let me know!

Do you have 127.0.0.1 whitelisted so it doesn't require a login?

[guenniac]

Yes it is in the list!

As a side note domoticz.executeShellCommand will execute asynchronously vs the old os.execute :

I went through all my scripts and changed them as I've read where some others have had issues with not being able to run shell commands asynchronously and sometimes encountered errors/hangs.

@guenniac states that os.execute works fine.
I checked the sending of email by dzVents and it works fine.
Why are you using data to store the emailaddress? Why not just in a variable?
Did you try several emailaddresses?

[guenniac]

There's no difference in behavior when I use dz.email. Regardless what I try:
- local address like 'root@sau' or real address to a provider(<name>@vodafone.de)
- address in data or directly in the call (dz.email('message from your lockRS script', logtext, 'root@sau'))

Tests via "Setup -> Settings -> Email":
- with several valid addresses outside it works
- with local address (root@sau) it doesn't

Does dz.email use data from "Setup -> Settings -> Email" and sends email directly to the given email provider?

[EddyG]

As server in the email setup I use the smtp server from my provider with port 25.
"root@sau" is not really an emailaddress.

[guenniac]

You are right. In the settings I have my provider access data set and this works.
When using os.execute mails to "root@sau" will be send directly to my local mailbox. That works!
