The line/load wires do not matter to the HS200, but the HS220 needs to have the correct wiring to each screw.

 

Was there a previous dimmer switch that did work for both lights?

Damaris keep jumping out of Wi-Fi go on solid red or just flashing orange and green

@Tony Thanks for the response

The old switch was an on/off only, I was upgrading with the HS220 to have the dimming and smart capabilities. Anyway, just now I installed an old-school dimmer i had lying around, and confirmed the LED lights dimmed as expected.

While I had the HS220 out (and re-installed it), I confirmed that the line/load wiring was correct as well.

In the 4-light scenario, for funnsies, I put a single incandescent bulb mixed in with the dimmable LEDs, and the dimmer works as expected. What do you think this could be?

Apparently the issue may be the method of dimming the bulbs support. 

 

HS220 supports dimmable incandescent and LED lights based on TRIAC and forward-phase-control, and does not support lamps based on PWM (pulse width modulation) and ELV (electronic low voltage) dimming. It is recommended to contact the bulb manufacturers to see what dimming methods are supported.

@Jigg 

As @Tony stated above, it is the type of bulb!!

 

I had the same issue with 2 BR30's in 2 recessed lights.  Both were 11 W LED.  They would turn on but not dim.  If I took one of the LED's out and replaced with an Incandescent, then they would dim.

 

I went to the store, bought some new LED bulbs.  They work.

 

Philips bulbs (not the Hue's)  work.  TP-Link really needs to get a list of compatible bulbs since the none of the bulb manufacturers d list TP-Link as a supported dimmer.

 

The bulbs I bought were:

Philips

Model: 9290018703

Ordering Code: 7.2BR30/PER/927-22/P/E26/WG T20   

 

Home Depot  3pk for $9  I imagine other Philips non-Hue bulbs work as well.

 

 

Thanks for the responses all!

I understand now that it is from the type of bulb. It is unfortunate because the dimmer is an "led dimmer" and I bought led "dimmable" bulbs, and apparently that information is not enough in being able to plan ahead (I bought 12 matching bulbs). 

I appreciate @Tony 's response in clarifying the control type, unfortunate that this information is not in the specification page. This is similar to the LED manufacturer, where I don't know if it is PWM or ELV or control besides "Dimbable: yes" (I did contact TCP but they never returned my email). It seems it is left up to the consumer to throw money into the wind and see what works... hooray. (frustrating because it worked just fine with one bulb, rendering buying one bulb from a few manufacturer to try out kind of meaningless!)

Mini-rant over ;)

 

I will try some of those phillips bulbs you mentioned @mattstache. Hopefully their 5000K version looks good with the TCP 5000K non-dimming bulbs I already got here. Thanks for providing the spedific model you used.
