What the differences mean

Radios

The Eve Thermo uses Bluetooth and Thread, and Thread needs a border router. It has no Wi-Fi. The Shelly BLU TRV uses Bluetooth, and Wi-Fi only through a gateway that has to stay on. It has no Thread. Neither is a Zigbee valve. If the house is already Thread, the Eve head joins it. If the house is already a Shelly Bluetooth gateway, the Shelly head is the one that fits.

Apple Home and Matter

The Eve Thermo supports Apple Home and Matter. The Shelly BLU TRV supports neither. Alexa, Google Home, Home Assistant and SmartThings are on both. That split is why an Apple household lands on the Eve head even when the rest of the sheet looks close.

Frost, lock and away mode

Frost protection and a child lock are on the Eve Thermo and not on the Shelly BLU TRV. Geofencing is on the Eve Thermo and needs a hub. The Shelly BLU TRV has no geofencing. The Shelly head does support an external temperature sensor, which the Eve Thermo does not, so a room that reads hot because the sensor sits on the pipe is a Shelly problem you can move, and an Eve problem you cannot.

Battery figure

Both take two AA cells and both carry a 2-year warranty. The Shelly BLU TRV publishes a 2-year battery life. The Eve Thermo does not publish one, so the missing figure is not a loss and not a win. Weight is 130 g for the Eve head and 107 g for the Shelly head.

Which one to buy if

What owners say

Owners of both radiator valves say a single head on the valve is enough to stop heating an empty room, and both groups talk about fitting adapters and then leaving the schedule alone. Eve Thermo owners single out Apple Home pairing, control that does not require a cloud account, and geofencing that cuts the heating bill, and they complain that motor noise and plastic feel vary from unit to unit. Shelly BLU TRV owners single out quiet, accurate regulation and a quick install, and they warn that the gateway has to stay powered, that Bluetooth range depends on where that gateway sits, and that the head's own reading can be skewed by the radiator unless an external sensor is added.

Price history compared

Every price change of both, in the same store, so the gap between the two lines is what one costs more than the other.
