The Mysa thermostats seemed nice, but I didn't need HomeKit integration and they were more expensive. I was able to install two of these thermostats. One controls a fan-forced heater in the living room, and the other controls a baseboard heater in the bedroom. Both are paired with my Echo Show, and (with Alexa Routines) I've been able to automate home/away temperatures. Awesome hardware, and it was very easy to install. I had a 2-wire installation, so it was seamless. ### ⭐ 1.0 out of 5 stars Only worked for a year *by B***B on Reviewed in the United States 🇺🇸 on January 25, 2021* The product worked great for about a year. Then the temp control (up and down) stopped responding to input. Contact the company for a warranty replacement, received one reply and have since been ghosted.Please beware that the company seems to not honor their warranty. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Works great *by N***5 on Reviewed in the United States 🇺🇸 on October 6, 2020* This unit works great with control unit control heat from anywhere --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/122138821-asmt402-smart-home-thermostat-to-adds-maestro-connectivity-to-existing](https://www.desertcart.tn/products/122138821-asmt402-smart-home-thermostat-to-adds-maestro-connectivity-to-existing) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-09-21*
