Welke connector modbus rs485 op wtw

[maartenvdv737]

Ik wil een modbus aansluiting maken naar mijn wtw vanaf mijn home assistant. Nu lijkt dit een terminal block aansluiting te zijn, maar de female connector op de wtw lijkt toch anders dan de male connectors. Wie kan mij helpen het juiste merk/type te vinden (in de wtw handleiding staat niets).

Mogelijk is het deze: https://nl.farnell.com/ca...pluggable-3pos/dp/1717048

CTB92HE/3

Even goed kijken naar de pitch (afstand tussen pinnen).

Van die jumper wires kun je er ook zo op prikken, scheelt je de aanschaf van een connector

Goede tip, ik ga het met jumper wires proberen! Dank

Ik kan ook bevestigen dat de CTB92HE/3 de juiste connector is voor de modbus aansluiting op de Itho HRU 400.

Uit interesse en omdat ik hetzelfde apparaat heb, heb je dit aan de gang gekregen? Zou je misschien je swtup & ha sensors kunnen delen?

[maartenvdv737]

Ja dit is gelukt @feelthepower

Allereerst moet je de hru 400 verbinden met Home Assistant. Ik heb dit bekabeld gedaan met een UTP kabel waarvan ik 2 draden gebruik. Dit moet je aansluiten op een rs485 usb adapter, zoals deze: https://www.hobbyelectron...-seriele-communicatie-usb

Dit is mijn modbus.yaml

En in configuration.yaml zet je de inputs

code:

input_number:
  unbalanced_flow_zone1:
    name: Woonzone
    min: 15
    max: 270
    step: 1
    unit_of_measurement: m3/h
  unbalanced_flow_zone2:
    name: Slaap zone
    min: 20
    max: 130
    step: 1
    unit_of_measurement: m3/h
  unbalanced_flow_zone3:
    name: Natte zone
    min: 20
    max: 238
    step: 1
    unit_of_measurement: m3/h
  unbalanced_flow_zone4:
    name: Kookzone
    min: 20
    max: 115
    step: 1
    unit_of_measurement: m3/h
  
input_boolean:   
  zone1:
    name: Woonzone
  zone2:

  zone3:

  zone4:

  zone3_activate_humidity:
    name: Natte Zone geactiveerd Luchtvochtigheid
  zone3_off_started:
    name: Natte zone wordt uitgeschakeld

En dan heb je nog een reeks automations nodig

Dit was maanden uitzoekwerk. Hopelijk heb je er wat aan.

Ik heb zonekleppen in mijn systeem. Dus ook zones on de config.

Verder heb ik de nrgwatch non cve module om de itho co2 sensors uit te lezen via mqtt, zodat ik zelf volledige controle heb op de HRU 400 aansturing op basis van co2.

Laat maar weten als je specifieke vragen hebt.

Tof te zien dat er iemand anders bezig is met de hru400 aansturen! Hier heb ik de modbus verbinding via een esp32 met uart-rs485 opgezet, dus config iets anders, maar verder vergelijkbare plannen als jij al draaiend hebt

Snap ik verder goed dat jij de nrgwatch module met c1101 puur gebruikt om mee te luisteren met de Itho sensoren en drukknoppen, aangezien de hru400 de ethernet interface niet heeft?

Uit nieuwsgierigheid: welke humidity sensoren gebruik je voor de badkamer? Ik heb een paar Tuya TH sensoren liggen, maar de update-freq daarvan is nogal random.

Ik gebruik de nrgwatch om de itho co2 sensoren uit te lezen inderdaad. Met de drukknoppen doe ik niets. Alles gaat co2 gestuurd.

Luchtvochtigheid doe ik met de sonoff snzb-02. De mqtt updatefrequentie gaat omhoog als de gemeten Luchtvochtigheid wijzigt. Ik moet wel zeggen dat ik bij 1 unit last heb van een batterij die snel leeg is. Weet niet of dat komt door teveel vocht. Ik heb er nu 2 on de badkamer staan en die in een group gezet, zodat er altijd wel 1 werkt.

Ik heb een simpele formule die berekent of de Luchtvochtigheid snel stijgt (zoals de douche doet) en dan in 1x naar max afzuiging.

code:

  - platform: statistics
    name: "Bathroom humidity change over 20 measurements"
    entity_id: sensor.highest_humidity_wet_zone
    state_characteristic: change
    sampling_size: 5
    precision: 1

Hij zet de afzuiging weer terug na normaal 10 min nadat de Luchtvochtigheid weer onder een bepaalde drempel is gekomen (na het douchen)
