App useless without adequate server support

I bought six Sonoff devices to automate some lights and heaters and such in my home. The devices are inexpensive and, so far, work fine. The app is adequate though they really should get some native English speakers to correct issues in app and documentation that make it unclear.

The problem, it seems, is the servers you must use to make the switches work with Google Home, Alexa, and other devices. The company is not putting enough money and effort to upgrade these servers to support the larger customer base that comes with success. They should have anticipated it better. After all, they know how many units they’ve made and sold and can anticipate the increased usage.

Finally, their customer service is awful. Messages go unanswered for weeks, if answered at all and their website and Facebook page rarely provide status information. When they do post something, it’s just a message saying they are working on it and upgrading without any details.

I’m now researching ways to use the devices and bypass their servers, or any servers outside of my home.

Technically the app does what it says. However this app is so poorly designed that it should be pulled from the App Store by Apple for failure to meet design standards. Stereotypically Chinese in its problems. To name a few - the app display scaling has not been updated to meet Apples design standard since probably 2013 requirements. I use an iPad as a smart home hub and the buttons land on top of each other rendering them useless. Add to that the fact that you cannot log into multiple instances at the same time and it’s a recipe for incompatibility. Also, the select screens lack inertia making it cumbersome to scroll through them - scrolling inertia has been part of iOS design since the beginning in 2007!

Could be better

I have multiple Sonoff devices controlled by EWeLink and overall they work OK. The process to hook up new devices is a bit cumbersome the first time and sometimes requires multiple tries but overall once it is set up, it works consistently and reliably.

One way I found to allow controlling the app from multiple devices is to log into different accounts and share it. This allows me to control the app from my iPhone and iPad without logging in prior to using the app.
