Hello I have it together with an LTE/4G router from Huawei. Works perfectly. Sunrise uses FritzBox. This was also mentioned as compatible in the descriptions on the Internet.

No. Configure the router, connect the satellite somewhere within wifi range and you're done.

With a single TP-Link Deco M4 AC1200 device, Wi-Fi coverage can be up to about 260 square metres (about 2800 square feet), but a distance of 20 metres to an outdoor cottage may be at or beyond the optimal range, especially if there are obstacles such as walls or environmental interference. The Deco M4 supports mesh technology, which allows coverage to be extended by adding additional units to ensure a stable and fast signal in distant or separated areas. Therefore, to feed a PC, TV and other devices via Wi-Fi in a house about 20 metres away from the Fastweb Nexxt modem, a single Deco M4 may not guarantee optimal coverage and speed. It would be advisable to use at least two Deco M4 units to create a mesh network that effectively extends the Wi-Fi signal to the cottage, improving stability and connection quality.

The devices must always be connected to the power supply as they do not have a battery. They are designed as stationary mesh routers and require a constant power supply to provide a stable Wi-Fi network.

Yes, it is possible to expand the network with a Deco M4 if you already have Deco M5 units. - The TP-Link Deco series is designed to be compatible with each other, which means that Deco M5 and Deco M4 units can work together to form a unified mesh network. - You can add additional Deco M4 units to extend the coverage of your network as they use the same mesh technology and integrate seamlessly into the existing network.

Hello Anonymius, you misunderstand this question window. You are asking a buyer of this product. How should I know which deco powerline has. Kind regards

No. Only Wifi or LAN.

All TP-Link products with the "Deco" brand are compatible with each other.

I don't have anything to compare it to, but it works, I have six Decos in two flats connected as a mesh network.

I have 4x Deco M4 in use and they work well. I have no experience with other TP devices.

I think the figures for an M4 are wrong, because these Deco routers use similar technologies. But it's not 15 watts even with the Deco M5, I find information on the Internet that the power consumption is about 12 watts. What you could do, of course, is simply switch off additional Deco at night with the help of a Smart Switch, for example, i.e. perhaps only have one in operation. This set wouldn't be bad for that, it contains 3 smart sockets that you can then programme with scenes, so you could also save power at night and then reconnect more Deco to the network if necessary (but I wouldn't switch off the main Deco).

Yes, you can select between router and access point in the app.

Hello I have 4 Ecos distributed across the property. The LEDs are all switched on and off correctly according to the schedule.

Yes

They are 2 identical, only the configuration determines the function. In my case, both are access points.
