X-10 lights no longer dim

Not sure when it stopped as I do not dim these lights often, but my 5 X-10 light/lamp switches no longer dim through HASS. I know it initially worked when I started using HASS back in August and believe it worked though September. I tried something a couple of weeks ago and it did not work but it was not a big deal so I left it. I tried again this morning and it still did not work. I reset my CM11, reboot the Pi and subsequently restarted HASS (0.33.4).

I am able to dim them directly through HEYU so I know the devices themselves are working.

Any ideas? I have 2 LM465 and 3 WS467 along with various other non-lamp modules.

Looking at the code I’m pretty sure it never supported dimming control, it claims to in the interface and reports back max brightness when it is on.

I was asked about dimming earlier in the week for my component and added something today Dimming control over X10 lights/lamps
