    Update: just wanted to update that I had a few questions and customer service was also excellent. Answered me within a day and I was able to get the system working exactly how I needed it to! Alerts my phone if the temperature goes too high or too low.

    ☆☆☆☆☆

    Took some fiddling to connect to wifi, but got it in the end. So far, so good. The temperature read is +/-0.5F compared to the thermometer I have in the aquarium already (which is a cheap one, so I'm guessing this is the more accurate of the two). Seems to hold the temperature very steady. I bought this for peace of mind since we'll be away for two weeks, and I always worry that the heater will fail.

    Reviewed in Canada on August 29, 2024

    Le contrôleur de température Inkbird ITC-306A est un outil essentiel pour tout propriétaire d'aquarium ou de terrarium sérieux. L'installation est simple et intuitive, et la capacité de contrôler deux prises séparément permet une gestion fine de différents appareils de chauffage.

    Le plus grand atout de ce contrôleur est la fonction WiFi. Pouvoir surveiller et ajuster la température à distance via l'application mobile est incroyablement pratique, surtout si vous êtes souvent en déplacement. L'application est conviviale, et les alertes en temps réel vous avertissent immédiatement si la température sort de la plage définie.

    Avec une puissance de 1100 W, ce contrôleur peut gérer des chauffages puissants sans problème. La précision de la sonde est remarquable, et il maintient une température stable, ce qui est crucial pour la santé des poissons ou des reptiles.

    Le seul point d'amélioration serait d'ajouter une fonction d'historique de température dans l'application, mais cela reste un détail mineur par rapport aux nombreux avantages offerts.

    En résumé, l'Inkbird ITC-306A est un produit fiable et performant qui offre une tranquillité d'esprit totale pour la gestion de la température de vos aquariums et terrariums. Je le recommande vivement à tous les passionnés d'animaux aquatiques et terrestres.

    Reviewed in Canada on March 27, 2023

    The app is a bit strange, obviously translation from Chinese to English seems to be an issue. It does more or less work however. Mine had an issue where it kept flashing weird errors and after trying to troubleshoot, Inkbird just sent me another one free of charge. I think with a couple of firmware updates and software updates to make it a bit more intuitive, it'd be a great product. At least at this point I will be alerted low temp or high temp and have an easy read thermometer.

    Tip: when the app says have the device and phone close to the router for initial setup, they literally mean as close as possible. Set it up before putting the sensors into your fish tank.

    I bought this in July of 2023 and it has worked great up until Jan 2025 then a probe started to fail. The controller gave a warning message and never once put my fish in jeopardy. I contacted Inkbird, answered a couple questions and I had a new controller within a week. Thank you Inkbird! I also bought another one just so I have a backup going forward.

    5.0 out of 5 stars Plug and Play was just how easy it was.
    Reviewed in Canada on December 1, 2021
    Verified Purchase
    The installation of this was super simple. I basically suction cupped the probes to the back glass and plugged it in to the wall and plugged the heater in and it was ready to go. I connected the app to it and set it up. Everything was super easy, just one thing to remember. It will take a while to heat your tank to whatever temperature it needs to be at. so for the first run you need to make sure you adjust the Continuous heating time limit to something more then 6 hours as I didn't and got woken up as soon as I went to sleep with an alarm on the phone and a separate one on the controller itself.

    It comes with two sockets so you can plug dual heaters in if you so wish in case one heater dies. I've had it running for a bit and honestly i haven't had any issues.

    you may want to buy extra suction cups as the probes come with one on each. I didn't want the probes to float around so i anchored them both near the probe and higher up.

    The reason why I bought this was peace of mind, I had an old tank years ago that basically boiled all my fish as it over heated and i wasn't aware. it made me stop owning a fish tank for years. Since I just got back into it, i felt i needed to have my heating monitored and from my research this inkbird was right up my alley as i already had the app from the amazing bbq controller they make.
