Sorry for using English, the German forum is far more comprehensive than the English version....but I don't speak German.
After a few days of struggle, I am now successfully sending alarm notifications using DHCP for IP assignment and gmail. I am happy with the basic email function.
For commercial scale roll out, I will purchase multiple Easy E4-UC-12RCX1 and pre-install the same application software for each customer. I want to offer the email alarm notification feature, but each customer will have his own unique list of who to notify.
It seems that the only way to establish a recipient list is via the Project/email tab in easySoft7 and that implies a different version of the software installation for each customer. It seems that the only solution would be to sell the relay without a recipient list, and then, if he wishes to do so, ask the customer to submit a list of email addresses. The customer's contact list could then be loaded onto a MicroSD card (along with another copy of the application software) and have the customer install the new MicroSD card and run from the card.
It seems like a cumbersome solution. A better solution would be the capability to create or modify the recipient list via the webserver.
Does anyone have a better idea?
