ESP-NOW configuration shows non-remotes as "last device seen"

[simon-budig]

What happened?

I tried to configure an ESP-Now remote and could not get it to work. Turns out the "last seen device" shows the MAC of any espnow based message, regardless if it is a WIZ-style remote or not.

The "last seen device" should be changed to "last seen remote" and only show the MAC adresses if the package is a valid key from a wiz-style remote. This would avoid this specific confusion.

To Reproduce Bug

You can reproduce this bug if you have a device that spams the espnow protocol with non-wiz-style messages. Then the User interface shows a useless MAC address most of the time.

Expected Behavior

The "last seen device" information should only show devices that actually transmit usable wiz-style remote telegrams.

Install Method

Binary from WLED.me

What version of WLED?

WLED 0.15.4

wled also suports espnow sync, not only remotes.

But the information shown at the bottom of the wifi configuration page seems only useful for remotes, or am I missing something? Espnow based sync does not seem to need any configuration beyond enabling.

[DedeHai]

you are right, that is a breaking change I introduced when adding support for up to 10 espnow remotes. will fix it and try to add your suggestion.

Espnow based sync does not seem to need any configuration beyond enabling.

FYI, this is not true. Slave devices listen for master's broadcast. Master(s) being "linked remote(s)". Even with @DedeHai 's modification this is still valid. WLED will (and should) ignore unknown senders.

FYI2: "Last seen device" is a helper only. Unfortunately a poor one in a ESP-NOW flooded environment but at the time it was written ESP-NOW use was sparse.
