[Depecrated] My Next Manager for your Nest® Tstats (firmware below 2.3), Protects and Sensors: all Nest attributes available (home/away, motion detection, setTargetHumidity, setHotWaterBoost) for automation-and no throttling!

Hi, that's what I'm saying. The list of values in the rule engine interface should come from the supportedThermostatModes attribute in the driver which contains the eco mode.

But, the rule engine is using its own list of values which doesn't contain the eco mode. It's an issue to report to the rule engine's developer.

Regards
