I now have this working using a different Lighwave HACS integration. I was previously using the Lightwave v2 (Smart Series) custom integration that looks like it hasn’t be developed for a while. I have now switched to GitHub - LightwaveSmartHome/homeassistant-lightwave-smart: Lightwave custom component for Home Assistant. Requires a Link Plus hub (Smart Series / generation 2), but will control both generation 1 ("Connect Series") and generation 2 ("Smart Series") devices. and installed 3.5.32-beta which seems to now work with HA 2025.7.1.
