Every unit and meter Ventaurio speaks to
What is supported today, how it connects, and what to check before you buy.
Ventilation units
Vallox MV
WebSocket over the local network, plus MyVallox Cloud
Full support: live readings, profiles, boost, week programme, filter counter, bypass and defrost state, and the whole savings calculation. This is the unit the app was written against and the one every protocol detail was verified on.
Vents / Blauberg
The units' own protocol over the local network, plus the manufacturer's server for remote access
Full support: live readings, speeds and modes, the supply setpoint, the rotary exchanger, filter counter and reset, the unit's own week programme with its four intervals a day, and its timer. The protocol was mapped register by register against a live A21 panel. Covers the OEM relabels too — TwinFresh, SIKU, DUKA One, Oxxify and Flexit Roomie One WiFi V2.
Enervent
Modbus TCP (beta)
Readings, fan speed and modes. Needs the Modbus TCP gateway enabled on the unit.
Komfovent
Modbus TCP (beta)
Readings, fan speed and modes over the C6/C6M controller's Modbus interface.
Pluggit
Modbus TCP (beta)
Avent AP190, AP310 and AP460. The same controller is sold as Dantherm HCV, HCC, RCV, RCC and WG, and as Fränkische profi-air 250/360 flex and 130/180 flat — those work here too. Not the profi-air 250/400 <em>touch</em>, which is a different machine behind the same name and has no Modbus at all; and not Pluggit PluggEasy or the older Avent P300/P450.
Systemair SAVE
Modbus TCP (beta)
Readings, fan speed and user modes through the SAVE controller. Units badged Villavent — the VTR and VR ranges — are the same platform and work the same way.
Zehnder
ComfoConnect protobuf (beta)
ComfoAir Q and ComfoAir Flex, through a ComfoConnect gateway — the LAN C or the Pro that replaced it, both speaking the same protocol. The gateway finds itself on the network. Readings, the four fan steps, the bypass, the temperature profile and a timed boost; not the week programme, which the protocol does not expose. The ComfoAir 350/550 Classic line is a different machine and is not covered.
Helios
Modbus TCP (beta)
Readings and fan speed on easyControls units with Modbus enabled.
Power meters and smart plugs
Shelly
Gen1 and Gen2 over HTTP, plus the Shelly Cloud account
Any Shelly with power metering can be the ventilation meter. Channels of a multi-channel device are addressed individually, so one 4PRO can meter the unit and three other loads.
Tasmota
HTTP
Any Tasmota build that reports ENERGY in its status JSON.
TP-Link Tapo
Local protocol
P110 and P115 report power and today's energy.
TP-Link Kasa
Local protocol
KP115 and HS110.
ESPHome
Native API over HTTP
Any device exposing a power sensor.
FRITZ!DECT
TR-064
200 and 210 smart plugs through the FRITZ!Box.
Beta means it has been written against the manufacturer's register map and tested on a bench, not on years of somebody's house. If yours is not listed, write to us with the model — most units speak Modbus TCP, and an adapter is about a fortnight's work when there is an owner to test with.
iPhone · iOS 16 or newer · Android 7 or newer, installed from the link rather than from Play, and free while the beta lasts
