Remeha

Keep an eye on your Remeha heat pump and adjust it on the fly, all from Homey. See what your system is doing in real time and tweak settings whenever you need to. Use Flows to automate your comfort and save on energy costs. Supports the Remeha Elga Ace Split, Monoblock and All-in-One models. You will need a GTW-08 gateway with an RS485-to-Ethernet adapter to get your heat pump on the network. Optionally pair it with a Homey power meter for complete energy insights.

What’s new

Version 1.1.1 — Bugfix release. All 7 Flow triggers introduced in 1.1.0 (defrost, error, status change, hybrid mode, COP threshold) now actually fire — a bug prevented every one of them from triggering. Changing the gateway IP address, port or slave ID in the device settings now works, with validation, instead of silently failing; no re-pairing needed. Hot water setpoint now offers the documented 35–65 °C range and room setpoint 5–30 °C — existing devices receive the corrected ranges automatically, no re-pairing needed. Fixed nonsense energy meter readings (such as 238 million kWh) when the gateway serves partially unavailable registers. Failed register writes now report an error instead of appearing to succeed. Faster polling thanks to a reduced Modbus inter-read delay. The device now identifies as a Heat Pump instead of a Thermostat — if a Flow card no longer matches your device, re-select the device in that card. Removed the misleading 15 W standby power estimate; use the external energy meter Flow integration for real power and energy readings. New device images and refreshed icons.
