Hi @lmilcent,
I installed your IPX800 integration 
here is the screen for an ipx800 v5, the issue is that the relays, although considered as switches, are not switchable
If this can help you to feed Claude code, there is my GitHub repository where I published utilities for this range, you should be able to extract all the information from the APIs GitHub - cce66/Utilitaires_IPX800_X-Pool_Ecodevices_X-Display-V2_ScanDevice_Broker-Monitor_Modbus2Mqtt_Hub: Utilitaires IPX800, X-Pool, Ecodevices, X-Display V2, ScanDevice, Broker-Monitor, Modbus2Mqtt, Hubi · GitHub I will see for the tests having an ipx800v3 v4 v5 an ecodevice, ecodevice RT2, and ED3 plus X-Pool and others
