Here’s a hurdle you might want to avoid if you plan on converting your custom devicetypes to take advantage of the new “multiAttributeTile”:
Contrary to the 2.0 documentation note that states,
*[The multiAttributeTile() type option are currently a placeholder. The specified type does not change how the tile will appear.][1]*
…that is most definitely not true in practice (at least on Android). I was modifying my Nest thermostat device handler using a ‘type’ of “thermostat” (naturally), but the SECONDARY_CONTROL text would not render… UNTIL I changed to type:“lighting”. The same thing happened with my EcoNet vents - “generic” seemed to be the best match, but SECONDARY_CONTROL only worked with “lighting” type.
