- Reviewed in the United Kingdom on 10 February 2024Pattern Name: Add-OnsStyle Name: V3+ 1x Add-on Radiator ThermostatVerified PurchaseGather ‘round, fellow warmth seekers and smart home enthusiasts, for I have a tale that’ll make you chuckle, ponder, and perhaps rush to expand your own kingdom of cozy with the tado° Add-on - Smart Radiator Thermostat. Yes, I said “expand,” for my abode was already a bustling metropolis of tado° devices, each serving its lord (that’s me) with unwavering loyalty and precision.
Why, you ask, did I choose to add another tado° knight to my round table of radiators? The answer is simple: I was on a quest for the Holy Grail of home comfort, a quest that led me to the realization that one more thermostat was the missing piece in my puzzle of perfect temperature control.
Let me paint you a picture of life before this latest addition. Imagine a house so smart, it almost has a degree from Oxford. Yet, there was one room, a rebellious little nook, that remained as chilly as a penguin’s picnic. Enter the tado° Smart Radiator Thermostat, stage right.
Installation was easier than convincing a toddler that bedtime is fun. If I had a nickel for every time I’ve dealt with a more complicated setup, I’d have exactly zero nickels. It was as if the thermostat whispered sweet nothings to the radiator, and voilà, they were in sync, spreading warmth like a gossip spreads news.
Now, let’s talk about the real magic - the control. With the tado° app, I wield the power of warmth like a wizard with his wand. At the flick of a finger, I can summon heat to the far reaches of my castle (okay, it’s a semi-detached, but let’s not get hung up on details). And the energy savings? Let’s just say my wallet is fatter than it’s been in years, all thanks to the efficiency of my tado° setup.
But the pièce de résistance, my friends, is the way this thermostat has brought harmony to my home. No longer do I engage in thermostat wars with my household. We live in a utopia of temperature perfection, where every room is just right, every moment of the day.
In conclusion, adding another tado° Smart Radiator Thermostat to my collection was akin to adding another star to the night sky - it just made everything brighter. If you’re on the fence about expanding your tado° empire, let me nudge you over with a promise of warmth, efficiency, and a touch of magic.
Five stars, because in a world where you can be anything, tado° chooses to be awesome.
- Reviewed in the United Kingdom on 15 November 2023We've had a Tado system in our house for 8-9 years, but for one reason or another it's been a single smart TRV and a wireless thermostat arrangement. It's only recently I learned about the basic version of their TRV, which eschews some functionality of the more expensive model for cost savings.
These models are basic - they don't support the air comfort features etc - and don't have the same digital display on the unit itself. But considering how fit and forget TRVs are supposed to be, paying extra for a visual feature seems superfluous, and the air comfort features are nice to have but by no means essential.
The basic TRVs arrived as expected - bare bones with a few fitting adaptors for different kinds of radiators. I assumed in advance that the fitting I needed wouldn't be included, and I was correct. Even if an included adaptor works for you, they're made of plastic so might not standup to long term use. As it is, adaptors that I need run to about £10 - though made of metal - but it's worth noting the extra cost per unit.
That aside - everything worked as planned. I'm very used to the Tado system, so appreciate that some calibration is often needed to get the TRV to reflect a more accurate room temp than what it's picking up next to the actual radiator - but it's easy enough to do with the phone app.
I can't find any fault with them - five stars all round.
- Reviewed in the United Kingdom on 26 July 2024Pattern Name: Add-OnsStyle Name: V3+ 1x Add-on Radiator ThermostatVerified PurchaseThis works great, it allows me to control the temperature in my bedroom separately from the rest of the house, so I don't need to heat the bedroom whilst heating the rest of the house, stops waste and saves money, a double win.

- Reviewed in the United Kingdom on 19 May 2024Pattern Name: Add-OnsStyle Name: V3+ 1x Add-on Radiator ThermostatVerified PurchaseI have Tado thermostats on all radiators in my house and am very satisfied with the performance. Initially, I wasn't happy with the temperature control in some rooms but, as others have noted, I found that this was caused by vertical valve installations which allowed the sensor head to detect direct radiated heat from the radiator. After refitting the valves so that the Tado sensor was horizontal and pointing away from the radiator, everything worked perfectly. The app also works well and it is very easy to set temperatures, schedules, etc. for individual rooms. A bit pricey but highly recommended.

5.0 out of 5 stars Un produit parfait
Pattern Name: Add-OnsStyle Name: V3+ 1x Add-on Radiator ThermostatVerified PurchaseJe possède une vanne thermostatique Tado depuis 2018. J'en suis tellement satisfait que j'ai progressivement remplacé toutes mes vannes thermostatiques par des vannes Tado. Elles sont très faciles à installer, de très bonne qualité, les piles durent assez longtemps (environ 1 an demi à 2 ans), et sont très précises dans leur mesure de la température. L'application associée est leur grand atout, car elle permet beaucoup de paramètres et la possibilité de faire un planning précis pièce par pièce. Je recommande chaudement (vous l'avez ?)

5.0 out of 5 stars comoda ed effciente
Pattern Name: Add-OnsStyle Name: BASIC Radiator Thermostat Add-on x3Verified PurchaseAbbiamo installato il tado kit base al posto di un vecchio termostato nella zona notte ed una valvola in ciascun termosofone (in tutto 6 per 5 stanze). ogni termosifone può avere una programmazione autonoma (fasce orarie, temperatura), che può essere facilmente gestita tramite un'app, scaricabile e gestibile da più utenti. è fantastico, ogni stanza gode di un proprio clima, con evidenti vantaggi, in quanto posso verificare in ogni momento se qualcuno ha dimenticato il riscaldamento acceso, rileva le finestre aperte, è gestibile con comandi vocali da Alexa. L'app offre la possibilità di monitorare i consumi e di rilevare gli utenti grazie alla geolocalizzazione. L'installazione è stata veramente facile e non abbiamo incontrato alcuna difficoltà, è sufficiente seguire le istruzioni.
