Gpoint Yandex Locator luci-app-gpoint

Hello everyone! I have a ZBT-WE826T2 router with a DW5821e modem. We installed luci-app-gpoint and gpsd on openWRT. We work with a Megafon SIM card via GPSD GPS, it determines the location on the street, everything is fine.
I want to try Yandex Locator, so that it also determines the location. I received a free trial API from Yandex for 1000 requests, entered it in the "API Key", saved, rebooted the router. After rebooting, "Service control" says "Yandex Locator: getting navigation data..." I can't get the location... I assume that this service needs something else, since in addition to entering the "API Key" there is also "Interface" which suggests selecting some wifi interface for Yandex Locator. But no matter what I do, I am not given a choice of interface, it always says "Wifi not found".
Please tell me how this works, maybe someone knows? What should I do to get the location using Yandex Locator?

This is not shipped from openwrt.org
You need to ask where you got it from

ok, thank you
