I like my Sonoff devices however the App still (after 3 years) has a lot missing.
We were promised local control over 3 years ago and they still don't have it working with all devices (so the app says).
It took them over a year to learn local control meant using the Lan not using phone data.
So your giving up on x10 because you can't get dusk/dawn timers to work from an app and moving to another protocol whos app doesn't even have that option (at least not that I can see).
I thought Dusk /Dawn was a must have?
Unlike the Sonoff eWeLink app the X10 wi-fi app has only been available since the start of the year.
The eWeLink app is on version 3.50 last time I looked and the app is over 3 years old, my one Sonoff module has had at least 2 firmware updates (that actually installed) tripple that if you want to count failed updates.
The X10 Wi-Fi app is on 2.0.07 and less then 8 months old and I've done 3 firmware updates. 1 failed but that never made it past testing.
To me it looks like Authinix is working on their app better then itlead. the last time I was on the itlead forum an app update was 3 months past the announced release date with no reason for it.
And don't get me on the Sonoff Alexa skill
The X10 wifi app Dusk/Dawn times being off issue has been an issue in the apps for some time (since release for some) the change to DST brought to light where the issue was.
