Can I connect the TRVZB heating thermostat without a gateway?
No, you need to pair with a Zigbee Gateway that supports using the Zigbee 3.0 protocol via the app under a 2.4Ghz network condition. Such as SONOFF Zigbee Gateway NSPanel Pro, ZB Bridge Pro, ihost and ZBDongle-E.

Totally recommended
Bought this along with two extra TRVs. It lets you configure the % a valve opens and closes meaning you can balance your radiators and get rid of noises. It also improves comfort, and integrates well with sonoff thermostats you can place around the room for even more comfort. The zigbee hub is also awesome – works with Home Assist quite well.

Not a bad product could be with some improvement
Its works great for the price. The value adapters donât fit every radiator so check the size of your valve before buying. I also got the temperature sensor which makes it work better. I can only control it using the app eWeLink does not work with sonoff NSpanel. SmartThings only lets you turn it off and on and you canât change the temperature.

Tend to have minds of their own
Not so easy to control as they sometimes do not work even in manual control, also do not follow the schedule set.

Product is fine but missing parts
So the product arrived fine but I expected to receive the batteries also with it as the listing stated batteries included well they are not spoke to Amazon and wanted me to return a working product for no barriers rather than just sending new batteries or partial refund to purchase some so yes Amazon was no help so just know when purchasing that you do not get batteries!!!!!

Niente di più pratico è comodo, il costo è un poâ più alto rispetto ad altre termovalvole ma vale la pena di acquistarle. Possono avere senso per chi come me ha un impianto centralizzato e non apro tutti i caloriferi, con possibilità di impostarle in manuale o in automatica con programmazione settimanale del tempo che si vuole accenderle/spegnerle, non ho riscontrato nessuna problematica di funzionamento fino ad oggi, lâunica critica sono gli aggiornamenti firmware.. quando arriva ovviamente câè il classico aggiornamento, e per poterla aggiornare ho dovuto provare mille volte.. da considerare la necessità di acquistare la prima volta lâHub con la versione Pro ovviamente (altrimenti non si associano) Per me è 4 stelle a causa della problematica del firmare iniziale, per il resto ripeto le ho montate da qualche mese e non hanno mai perso un colpo. Nota molto positiva è la calibrazione automatica dello spillo la prima volta che si accendono, ottimi i materiali e davvero funzionale. Consigliate assolutamente A++

Parfait, bien visser la tête une fois allumée pour lâassocier, règle parfaitement la température, programmation facile. Attention, le hub ne connecte que 10 têtes.

Jâai acheté le Sonoff TRVZB pour mieux gérer la température de mes radiateurs sans avoir à régler manuellement chaque vanne. Dans lâensemble, câest un bon produit, mais il y a quelques petits points qui pourraient être améliorés.â Ce que jâai aimé :â Installation rapide et facile : Je lâai installé en quelques minutes grâce aux adaptateurs fournis. Aucun problème pour lâadapter à mon radiateur.â Intégration domotique pratique : Fonctionne bien avec Zigbee, et je lâai connecté sans souci à Home Assistant. Le contrôle à distance et la programmation sont un vrai plus.â Fonctionnalités utiles : La détection dâouverture de fenêtre, la sécurité enfant et la protection contre le gel sont bien pensées.â Bon rapport qualité/prix : Pour le prix, il fait largement le job et offre des fonctionnalités similaires à des modèles plus chers.â Ce que jâaurais aimé voir amélioré :â Un peu bruyant : Le moteur fait un léger bruit quand il ajuste la température. Ce nâest pas insupportable, mais si câest dans une chambre, ça peut gêner.â Température pas toujours précise : Jâai remarqué un petit écart entre la température affichée et la température réelle de la pièce. Jâai dû compenser avec un capteur externe.â Notice pas hyper claire : Lâinstallation est simple, mais la doc pourrait être plus détaillée, surtout pour les adaptateurs.â Passerelle Zigbee obligatoire : Attention, il faut absolument une passerelle Zigbee pour faire fonctionner ce thermostat, ce qui peut être un frein si vous nâêtes pas déjà équipé.ð¡ Mon avis final :Globalement, je suis satisfait du Sonoff TRVZB. Il fait bien son travail et permet un bon contrôle du chauffage à distance. Malgré quelques petits défauts, il reste un excellent choix pour son prix, à condition dâavoir une passerelle Zigbee.

You have to do a software update for the thermostat and the bridge in order to control the percentage for the opening of the valve. By default it is either 0% or 100%
