WiFi Relay: after web update the relay stop to work

Hi all!

I’ve just updated via web interface an almost never used WiFi Relay (single channel version) with the latest firmware available: v3190 Oct 20th 2017

after a reboot the device works as expected but when I switch on and off the relay via web interface nothing happen, no click and no red led…

This is what I can read from the firmware page:

Firmware version: 3190 / Oct 20 2017 11:09:48 , SDK: 2.1.0(7106d38), User bin: 0, bootloader version: 5.
Free heap size:29272
Running user1.bin

I bought the device 2 years ago (but I never use it, so it is new) as a spare part of another one that works normally and it shows:

Firmware version: 3190 / Oct 20 2017 11:09:48 , SDK: 2.1.0(7106d38), User bin: 1, bootloader version: 5.
Free heap size:26336
Running user2.bin

My question is why one device shows “user bin: 1” / “user2.bin” and the other one “user bin: 0” / “user1.bin” ? The firmware shoud be the same so I’m expecting the same information on the firmware page. Is this related with the malfunction of the device?

Thank you.
