Hmm If you mean controlling sonoff via webhook then yes although ewelink ecosystem does not have the ability to receive a variable value.
Not many other options directly in SEQU. Apart from email, you can technically set up any webhook or IFTTT. Alternatively, you can pair your ewelink account with SEQU and then you can add a Sonoff device as an action… for example, start led369 as a notification.
If you have ewelink web, you can create a webhook as IF and use it to initiate some sonoff device, but it’s the same as above, only done a little differently.
However, if you wanted to use ewelink notifications, it would be difficult or impossible.
If you use Android, you can look into MacroDroid, which has its own webhook as a trigger. Then you can make almost any solution for the notification.
Tell us what kind of notification you would like exactly, and we’ll think about it together.
Unfortunately I don’t know anything similar for apple.
Buy the cheapest phone/tablet and put it in your home as a central solution.
More seriously, if you have a paid ewelink plan, look at IFTTT, they should have something similar and then from SEQU via webhook to IFTTT you will initiate a notification.
There are indeed services that integrate notifications via webhook call and send them to WhatsApp, but most of them are $ and more or less require delving into the topic because they are not simple click-click solutions.
So the eWeLink Advanced Plan doesn’t give you any extras in IFTTT except for the fact that there is the possibility of pairing hmmm… Strange… I used to think it gave me something but maybe I remember wrong.
I’m telling you, buy yourself the cheapest phone/tablet with Android (9 above) and MacroDroid and make your own notifications forget about the greedy IFTTT…
Apparently a lot has changed because the last time I touched IFTTT the free version gave many more options and 5 applets and now 2.
