Great quality sensor
I have 8 of these sensors and they work flawlessly. I connected those to Meross hubs (300 and 450 models) without issues. They work with Home Assistant through Meross LAN integration. 3 months of use and batteries report 100%, although some of my sensors get very little sun light, charging mostly from ceiling lamp, which I do not use much at all. The temperature varies of where you place them, as they need light to charge and put on a window, be aware this is the coldest and most humid spot.

Excellent Customer Support
Very impressed with the Meross Customer Support. My temp/humidity sensor stopped working after a few months so I reached out for support. They replied quickly and after a few diagnostic steps offered to replace the unit without any fuss. Replacement working fine - happy customer! Would recommend these sensors, will buy again.

Very accurate
Very accurate, has stayed at 100% charge whilst being kept in a typical room that receives light. I use this to operate a heater and it’s very effective.

Simple but effective
These need a hub but once that is installed and the thermometer paired they work really well. If they are kept in an external light source the solar panel keeps the battery charged. Much better than the earlier model that consumed battery's. I have had one outside in a gree house for over a year and working fine on the original battery. As s Meross device I have it linked to a Meross Smart Plug which turns a heater on and off between temperature limits. Very happy, I have 3 overall round the house - they just need to have access to light to keep them charged

Good but does need light to power it
Got lots of Meross stuff, which all works well. This is their 2nd generation thermometer, the first had very short battery life. This one gets round that using photocells to power it. That works provided you only use it where it will get good light. In the loft it shut down after about a month. This one is not designed to have its supplementary battery replaced.

Great addition to a smart home.
The solar room thermometers work very well when paired with a hub. I purchased these alongside a smart home MeRoss smoke/fire detector. These have been in my home for the last year they’ve worked very well and outside of a battery warning after dropping one of the units. It was a simple case of pushing the battery back in again I’ve had no issues with battery life or the recharging due to the solar cell on them, the temperature data and humidity data is easy to download via the Meross app. Considering the cost of other units out there. These are extremely good value and once paired work extremely well.

Mixed reliability
Bought 2 of the sensors and sadly one stopped working after a few weeks, but the other is still going. They seem pretty accurate and easy to setup.
