Unless I am missing something, the hardware hasn't changed at all. The older model will receive a Matter support via firmware upgrade, so this looks to be just a repackaging.
It is exactly like that and I would not recommend updating the older model to Matter. In an Apple environment it has no benefit. I have a lot of HomeKit Eve Energy plugs in use and a couple of months ago bought a new one that already had the Matter firmware on it. Once plugged in that it broke down the Thread HomeKit network. Every node and end-point device (such as the Eve Weather station) near this Matter enabled Eve Energy would lose its connection - no more connection to the Home app and everything else. I had to unplug this Eve Energy from power to solve the problem. A replacement unit did exactly the same and Eve Support basically denied that there was a Matter firmware issue, even though similar incidents could be found on several forums.
What is the use of a personal weather station that does not record rainfall?
Yeah... well I would like to have it detect if it is starting to rain (or snow). Currently I have an automation that controls the motorised awning and a couple of windows. It uses Eve Weather data (temperature, humidity and trend), a light sensor, sun position and some weather forecast data from the internet. It works most of the time, but it is hard to find the right values and triggers to detect upcoming rain that is very regional.
This is exactly the type of display/information that Apple should put onto the side of their Homepods.
Weather, Time, Music info, Timer, Notification icon.
Simple, Useful graphics on the side of a homepod, underneath the cloth
Naah, I had this option on our Gigaset phones in the house. Turned it off after a while because the same info is shown on the iPhone in the morning anyway and that's what most of us at home look at. I don't see the need for a screen on a speaker anyway.
I find all Eve accessories to be garbage. They fail frequently and their customer support in Europe is dire. I have four Eve energy sockets in a drawer along with an old style Eve Weather unit, and my wife bought me the newer style Eve Weather as a gift. It works, but it's pretty crappy.
If you want decent gear, use a Meross socket and a Netatmo weather station if you want proper weather monitoring. It's obviously more expensive, but you get what you pay for.
Overall, I would avoid all Eve products. They are overpriced paperweights.
Netatmo is very overpriced too if you ask me. I agree that Eve Support is bad, tickets get messed up and it seems that only one person is the support employee on the site, not really answering serious questions.
I have considered the Netatmo weather sensor, but I don't like its cloud dependence. When the DSL is down, most functions just won't work any more. Also there's the risk that in a few years the cloud servers simply won't support "older" models. And I don't see why something like weather sensor needs a cloud service. Current small computers are powerful enough to do weather calculations themselves either with or without some other weather data from the internet.
About Eve... I have a lot of Eve devices both HomeKit Thread and HomeKit bluetooth. The Thread enabled ones have a great coverage too. I have a door sensor in the garage and while it is 15 meters from the house, it still triggers almost instantly. Before I installed it, I had used a HUE motion sensor, but that thing was slow and lost its connection very often. HomeKit thread from Eve works great. I don't use Matter (see above).
I'm still waiting for (grid powered) fire/smoke detectors with HomeKit Thread option.
