Sonoff WiFi DIY Relay Modules - lot of 2 - eWeLink, Smartthings

Description

Sonoff WiFi DIY Relay Modules - lot of 2.  One is new, in original packaging.  The other was used and removed in good working order.  Both items are offered in good faith.
Compatibility - eWeLink is the native application, though they announced integration with Smartthings recently.  No separate hub is required, since all of the integrations are WiFi and cloud-based.
Sonoff SV (Safe Voltage) model
IM160220004.  Complete factory specs can be found on the Itead website.
This model is for 5-24V operation and switching.
Sonoff Inching / Self-Locking model IM160722001.  It can be powered by micro-USB 5V or a separate 7-32V (AC/DC) input.  The relay has both Normally Open and Normally Closed contacts available.  This appears to be discontinued, though setup instructions remain on the ewelink coolkit website.  Ebay policy does not allow me to provide direct links.
I used the second module as a WiFi control for my garage door opener.  It has a native "inching" function that emulates a momentary button press.  There are 3 pins soldered to connector "CN4", which I used for a separate logic level input.  Sonoff used to offer an optional RF remote control that would be populated in CN4, so I took advantage of the available pins.
