Hi,
Is it possible to connect the SONOFF app to Apilio? If not directly like in the case of Smart Life/Tuya then perhaps indirectly somehow?
Sonoff also has a the “eWeLink” platform, which is integrated with IFTTT.
eWeLink also support webhooks, which you can use with Apilio.
I’m not an owner of Sonoff devices, so I’m not sure if you can use all of them with eWeLink. But if they do work with eWeLink, chance is good that you can connect them with Apilio through either ways mentioned.
