Only thing: You can not use it on a Slave Domoticz and read the info on the Master Domoticz. The Device is not shown in list of "not used"devices on the Master Domoticz.

Maybe thats it thing to look at. Rest briljant plugin. Now i can check if my VPN is on !!
This depends on which type of devices/switches are allowed to be remotely transferred from Domoticz. This is not something that can be defined from plugin itself.

br,

Strage, did you change to new version (1.1.0)? or you still have the previous one?
Can you give more details?

@EdwinK,

You will see this in the log if the plugin Heartbeat is ever greater than (or equal to) 30 seconds because Domotoicz doesn't like it.

The plugin will work just fine, that is just a warning.

When installing the plugin I get the following error and Domoticz will not start. Kind of strange that my GPIO export settings will make the script fail?

All help is appreciated. Thanks.

I installed this following the instructions. Logged in and then did sudo su.
Created the plugin.py in a new subdir under "plugins".
Restarted Domoticz. No errors, but I don't see the WAN checker in the hardware setup dropdown...

D you have python properly installed?

OK, this tells me how to install. But how can I check if it is already installed or not?

if you try to install, you will be prompted when the package is already installed.

Sure enough: that second install did it. I can now add the IP checker in the HW tab. Thanks!

Thanks for the plugin, and thanks to the creator :D works great!

Now I would like to do one thing with this script, send myself an email when the WAN IP changes :D, of course, with the IP in the message.

Now I have created this script:

1.PNG (18.27 KiB) Viewed 2094 times
But this is the result:

2.PNG (5.2 KiB) Viewed 2094 times
Anyone know how I can get the correct utility value in the email/notification?

Thanks!

I have done exactly that today! Even made sure I only receive one e-mail per day. Otherwise you may wake up with a mailbox full of warnings..
The only thing is: It is not in Blockly, but in LUA. If you have the courage to get into LUA, I can post my small LUA script here...

It may post several times an hour, but only if the WAN does actually change, thats why I made the user variable. But I dont understand why this doesnt work, even when I email the utility it just saids utility(358) instead of the actual value.

But if you could post it, I would much appreciate !

Thanks!

It would actually be smoother to integrate this functionality into the Plugin itself. I would need to do some Python exercises first, I am an experienced C programmer but this is just a little bit different.

You could have the e-mail script triggered by a change in the text device: once the WAN address changes, the plugin will change the text and it would then trigger the mail. Probably. It makes the whole mechanism somewhat easier, and it will result in one single e-mail after a change of the WAN address. But I want to have one mail per day, in case I miss a warning mail. It will keep sending the daily mail, until I have changed my DNS entry and also stored the new IP address in my user variable.

My script works like this: I store the currently known WAN address in a user variable, and check that. If it changes, I compose and send an e-mail, and store the date in another user variable. The next time I want to send an email, I check the date: if it is the same I donot send. This way I only get one single warning message per day.

Code dependency:
two user variables (type string):
"WAN IP" contains the last known WAN IP address
"WAN IP Warning sent" contains the date on which a warning was sent (to make sure one warning is sent per day, not more/less)
one text device, as created by the plugin, named "WAN IP".

Code: Select all

-- This script will periodically check if the WAN IP is changed

commandArray = {}

-- get stored WAN IP address
VAR_IP = uservariables['WAN IP']
-- get current WAN IP address
WAN_IP = otherdevices_svalues['WAN IP']

-- check if current WAN IP address has changed
if (VAR_IP ~= WAN_IP) then 
    -- check if warning was already sent today
    curr_date = os.date('%Y-%m-%d')
    sent_date = uservariables['WAN IP Warning sent']
    if (sent_date ~= curr_date) then
        print ("Warning! WAN IP has changed!")
        
        -- compose text for warning e-mail
        Subject = "WAP IP address has changed"
        Body = " The WAN IP address in De Meern seems to have changed. Previous address was "..VAR_IP..". Current address is "..WAN_IP..". Please check, and change the DNS entry at Hostnet."
        -- send warning e-mail to admin (address is stored in uservariable AdminMail)
        commandArray['SendEmail'] = Subject .. "#" .. Body .. "#" .. uservariables['AdminMail']
 
        -- store current date to indicate warning has been sent
        commandArray['Variable:WAN IP Warning sent'] = curr_date
    end
else 
    -- clear warning sent field, if necessary
    if (uservariables['WAN IP Warning sent'] ~= ".") then
        commandArray['Variable:WAN IP Warning sent'] = "."
    end 
end

return commandArray
