-- dzvents script to switch on pump for floorheating
-- author: hkhk (Hendrik)
-- During summer time switch on pump every day for 2 minutes
-- During winter time only switch on if water temp higher than xxx
-- Water temp measured by Original Xiaomi Aqara Temperature Humidity Sensor
-- Pump switched with Osram wall plug
