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 2.2.1 — Everything since 1.1.1 in one release. The app now runs on Homey's Node.js runtime instead of Python. That is what makes it installable on Homey Pro (2016 - 2019), which does not support Python apps. Lifetime counters (compressor starts and hours, pump starts, backup heater hours and starts, generator starts) were always 0 and now show the real values of the heat pump. DHW energy consumption is now read from the right register, which ends readings such as 238 million kWh. A hot-water-only cycle now shows as "Hot water" in the status. All meters fill in right after the app starts instead of after up to five minutes. New: a "CH function enabled" switch that shows and changes whether the appliance handles heating demand at all. With it off, the heat pump does not start for heating whatever the room setpoint, while hot water keeps working. Devices that are already paired get the switch automatically, no re-pairing needed. New device setting "Log writes to the timeline", off by default. With it on, every value the app writes to the heat pump appears in the Homey timeline with the register and the value. That answers a question the app could not answer before: a setting that changes without a timeline entry was changed by the appliance, its room unit or the Remeha cloud, not through Homey. Also new: device icons per model, drawn after the real units: the indoor unit for the Hybrid Split, the control box for the Monoblock and the indoor unit with built-in gas boiler for the All-in-One. Paired devices pick up the new icon on their own. Fixed: once a fault had cleared, the status stayed on "Error" until the app restarted, which also hid every status change after it. Fixed: a heat pump that was unreachable at startup could stay marked unavailable even after it answered again. Changed: the thermostat mode now offers only the three modes the appliance has (Automatic, Heat, Off). "Cool" used to be selectable and silently switched to the schedule instead. Changed: a register this appliance does not have is dropped from the poll after three refused reads, instead of running into a timeout every cycle.
