It's not that straight forward.... However, you can leverage a library I have for that. Add fibaroExtra.lua to your QA https://forum.fibaro.com/topic/54538-fibaroextra/   Then in your QA main: local clim = 120 function QuickApp:updateClima() self:updateView("label1", "text", tostring(fibaro.getValue(clim, "power")).."W") end function QuickApp:onInit() self:debug(self.clima) self:updateClima() self:event({type='device', id=clima, property='power'}, function(env) self:updateClima() end ) end
