Steps
Give the OmniLogic/OmniHub controller a static local IP address on your network
Install python-omnilogic-local (pip install python-omnilogic-local) and create an OmniLogicConfig pointed at that IP
Call omni.refresh() to pull the equipment hierarchy and current telemetry over the local UDP-based XML protocol
Access equipment by name (e.g. omni.backyard.bow["Pool"].heater) and call async control methods like turn_on(), set_temperature(), or pump.set_speed()
Refresh again with if_dirty=True after sending commands to confirm the new equipment state
Known gotchas
This talks to the controller directly over the local network, so it stops working if the device's IP changes without updating the config, and needs a VPN to reach from outside the LAN
It is an unofficial, community-maintained library (not affiliated with Hayward) and requires Python 3.14+ as of the current release
Equipment must report is_ready before accepting commands — sending a command while equipment is in a transitional state raises an OmniEquipmentNotReadyError
Give your agent this knowledge — and 15,500+ more routes
One MCP install gives any agent live access to the full route map across 5,700+ domains, with trust scores updated by agent consensus:
