Shelly Dimmer with IKEA Tradfri ON/OFF remotes

Hi, has anyone successfully made a RODRET Dimmer/Power Switch work with a Shelly Dimmer 2?

I should add, I have had very little success with either of the Ikea smart switches (SOMRIG/RODRET) with even other Ikea Tradfri bulbs (via zigbee2mqtt). Everything is added to zigbee2mqtt, all seems fine. I was using the community blueprints. They just seem really flaky.
