tested on KeeneticOS v3.8.7 & OpenWrt v23.05.5
First, set up FT on your OpenWrt devices.
Then, change the mode of your Keenetic (?) devices to Extender (there are Repeater/Extender and Access Point/Extender, the last is the recommended).
Go to the Access Point/Extender (Repeater/Extender) > Home segment menu. Change the settings of the Wi-Fi network to those ones in OpenWrt.
Scroll below to the "Roaming for wireless devices" section. Enable "Fast transition (802.11r)" and write your mobility domain ID converted to the ASCII format.
You can use an online converter like this one: https://www.rapidtables.com/convert/number/hex-to-ascii.html. Keep the "Mobility domain key" field unedited.
Press the "Save" button. Now you have a so-called "Wi-Fi system" with use of both KeeneticOS and OpenWrt!
