I have bought the normal heating-valves and they are sending the actually temperature too.
This device i use.
http://www.elv.de/max-heizkoerperthermostat-arr-bausatz.html
and this is the debug string
'0f885e': { type: 'Heating Thermostat', address: '0f885e', serial: 'LEQ10043', name: 'Thermostat 1', roomId: 2, comfortTemperature: 21, ecoTemperature: 16.5, maxTemperature: 30.5, minTemperature: 4.5, temperatureOffset: 3.5, windowOpenTemperature: 12, valve: 14, setpoint: 17, initialized: true, fromCmd: false, error: false, valid: true, dstActive: true, gateway_known: true, panelLocked: false, linkError: false, battery: 'ok', mode: 'auto', actualTemperature: 17.5 },
