I have no experience with the TREDANSEN blinds but a comment above indicates they should work with Hubitat, presumeably treating them just like FYRTUR. I don't know if this will be much help but here are is my change log entry from when I installed my FYRTUR shades:
Installed IKEA Tradfri Zigbee repeater and first Fyrtur shade.
At this time, there is no way to pair both the IKEA provided remote and Hubitat to the same shade, so I didn’t even bother pairing/installing the remote. Instead, I’ll use Hubitat to control it. Keep in mind that regardless, the shade can be controlled by pushing the up and down buttons on the shade itself to the left for the battery compartment.
Note that the Tradfri repeater is simply a Zigbee repeater. The provided repeaters aren’t necessary to the shade’s operation and can be used independently as a repeater where needed.
Generally followed steps below (italicized) found at Ikea Blinds - #114 by nkyspike, although I used a different driver (see below).
Step 1 - charge the battery pack. It’s 2,600 MAh and reports I’ve read state it should ‘last several months on a charge’.
Step 2 - Pair the Tradfri repeater in an outlet relatively close to the shade. To pair: Plug in the repeater into the USB plug and then into your outlet. The light will come on steady. To get it in pairing mode, with the repeater plugged in, use a safety-pin/sewing needle and insert it into the small hole next to the USB socket, you will feel the reset button and hold that down with the pin for 10-15 seconds. Remove the pin/needle and the white LED should start to blink. Then set your Hub to Zigbee discovery.
Step 3 - Mount/install the shade hardware - pretty basic and quick
Step 4 - Insert the battery pack into the blinds. There are two small buttons to the left of the battery door that manually operate the shade up and down.
Step 5 - Install the User Driver from @Ryan780 (thank you @Ryan780 ! ) which can be copied from this post (updated to version with battery reporting): Ikea Blinds
Step 6 - Pair the shade by following @Kev ‘s post quoted here. Remember to use the driver from step 5. After the LED on the blind turns on, set your Hub to Zigbee Pairing mode.
Kev:
Ok Managed to pair It this way.
Pair repeater with He.
Reboot He.
Reset blind:-
For wireless roller blind:
Press on both buttons for 5 seconds. A LED
will blink once to confirm the reset.
Step 7 - Set the Max Open and close states for the shade. Get the shade where you want it to be ‘most Open’ either via the manual buttons next to the battery or by using Hubitat device page/dashboard. Then double-tap the down button on the shade to the left of the battery pack. The shade will move up and down 1 CM if it was set properly. This now is equal to ‘100’ open for the shade.
Used the driver referenced in post [RELEASE] IKEA window roller blinds found at https://raw.githubusercontent.com/a4refillpad/hubitat-IKEA-window-blinds/master/IKEA-window-blind-driver-code.
Everything worked OK, but there are no good instructions for setting the max shade length; that is, when to stop when it is closing the shade. This is a one-time thing after the shade gets paired, but since it is Zigbee, it is relatively easy to re-pair. To start the pairing process, hold down both the up and down buttons (on the shade itself to the left of the battery compartment) until the LED lights. Then discover device in Hubitat. After pairing, you can put the shade down to its desired max length and then double tap either of the up or down buttons on the shade. If the process worked, the shade will roll up then back down just a centimeter or so.
