Review: Easy Smart Thermostat Alternative For Any DIY Enthusiast - I've been using Shelly devices for several years and have been consistently impressed. These add-ons are fantastic! I have one currently controlling my 240V, 3000W electric space heater. It's configured with one leg of the 240V connection (at 120V) running through the relay, which also powers the Shelly 1. This add-on is connected to a standard DS18B20 temperature probe. Using Shelly's virtual thermostat feature with this add-on, I can precisely control my shop's temperature from anywhere with an internet connection via the Shelly app. I also have another one of these units controlling an exhaust fan in a grow room, connected to a DHT20 temperature and humidity sensor. Both add-ons have been working flawlessly. You can use these devices with a variety of sensors, including soil temperature/moisture sensors, and they can be powered by DC as well. This adds tremendous value to Shelly Plus devices! I highly recommend these add-ons for any home automation project. They are easy to configure and use. In the future, I plan to add a display unit and an OpenHab server to create custom widgets showing the temperature and other metrics all in a nice wall display.
Review: Ottimo - Perfetto grazie 🙏

### ⭐⭐⭐⭐⭐ Il complemento perfetto per chi vuole fare domotica sul serio!
*by B***X on 15 February 2026*

Ho preso questo Plus Add-On per integrarlo con uno Shelly Plus 1PM che gestisce l'automazione della caldaia. Da ex elettricista, trovo geniale l'idea di poter aggiungere ingressi analogici e digitali senza dover portare altri alimentatori in giro per la scatola di derivazione. Si aggancia a incastro sopra lo Shelly Plus (quelli con il chip ESP32 per intenderci) e via, hai subito a disposizione i pin per collegare sonde di temperatura DS18B20 o sensori di umidità. Io l'ho usato per monitorare la temperatura di mandata dei tubi e devo dire che la precisione è ottima se si scelgono sonde di qualità. Cose tecniche da tenere a mente: Installazione: Si monta a pressione, ma occhio a centrare bene i pin. Se forzate come dei fabbri rischiate di piegare tutto e addio add-on. Versatilità: Oltre alle temperature, potete collegarci potenziometri o sensori di livello per i serbatoi (molto utile se avete un pozzo o una cisterna). Software: Da programmatore, apprezzo che Shelly lo veda subito. Potete creare scene basate sulla temperatura che fanno scattare il relè sotto in base a soglie precise, tutto in locale senza cloud. Il "difetto", se così vogliamo chiamarlo, è che aumenta lo spessore totale dello Shelly. Se già facevate fatica a chiudere la 503 con uno Shelly normale, con questo montato sopra diventa un’impresa eroica. Vi consiglio vivamente di usarlo solo se avete spazio o se lo montate su barra DIN nel quadro, altrimenti preparatevi a lanciare qualche bestemmia durante il montaggio. Il mio consiglio da tecnico: Un piccolo trucco: quando collegate i sensori (specialmente se sono quelli a filo lungo), assicuratevi che i collegamenti siano fatti a regola d’arte, magari con dei micro-connettori o saldature protette da termorestringente. lasciar i filini volanti dentro una scatola dove passa anche la 230V è una follia: se un filo del sensore tocca la fase, bruciate l’add-on, lo shelly e probabilmente pure quello che c'è collegato. Tenete i circuiti SELV (bassa tensione) ben separati dai cavi di potenza. In definitiva, se volete trasformare un semplice interruttore in una centralina di controllo climatica o di monitoraggio, questo è l'accessorio definitivo. Costa poco e apre un mondo di possibilità. Consigliatissimo per chi ha un po' di manualità e vuole un impianto che faccia davvero "cose intelligenti" invece di accendere solo una lampadina.
