It is however not 100% reliant on node red. I havent found an easy way of doing it inside node red itself, but HA offers a very quick and easy solution. a binary sensor - trend. so I let NR listen to that trigger. This is that code in HA (configuration > Binary sensor:
- platform: trend
sensors:
badkamer_relative_humidity_trigger_vochtig:
entity_id: sensor.philio_technology_corp_ph_pat02_b_eu_multisensor_2in1_relative_humidity
min_gradient: 0.08
device_class: moisture
