Review on meross Wireless Thermometer Hygrometer: Smart Sensor with Historical Data 🌡️ & Alert for Greenhouse, Wine Cellar, Baby Room – Hub Included by Jesus Gallagher

I have already rated this product that I have bought several times, but previous purchases indicate that the product is no longer available and the rating has disappeared. I hung two of these devices on my thermostat for several hours, then adjusted them to the thermostat and left them overnight. The next day they showed different temperatures, a few degrees above and below the thermostat. I reset it, left it on the thermostat, and the next morning the reading was off again by a few degrees. They were bought in early July and after 6 months the batteries in the devices stopped working. Not the company's best product.
