good friends, I have some sonoff mini zigbee devices, for a light strip and for a lamp, my question is, are these repeater devices?
If they are mains powered then yes...
If they are powered by the network, I did not know whether to act as a repeater, since I have read that some devices did not act as a repeater, that is, every device that goes to the network, is it a repeater?
No. Line-powered devices are typically repeaters. With very rare exception, battery-powered devices are not repeaters.

I created a map of my home zigbee2mqtt network to graphically illustrate the different types of nodes in a zigbee network, and also the difference between repeaters:
- The zigbee coordinator (equivalent to Hubitat hub) is shown as a solid blue star.
- Some battery powered devices are connected directly to the coordinator. These are shown by the solid green lines. These devices do not work as repeaters.
- The devices in blue are repeaters that are connected directly to the coordinator (solid blue lines) or indirectly to the coordinator via other repeaters (dashed blue lines)
- Battery powered devices that are connected to the coordinator only through repeaters are shown with dashed green lines.
- Notice that there are no end-devices that repeat through any of the battery-powered end-devices. This is because end-devices are designed not to repeat. They are "sleepy" and communicate with the coordinator (directly or indirectly) only when there is a change in device status (eg. sensor status).
Notice that the majority of battery powered devices are connected to the coordinator via repeaters. Only 10 devices are connected directly to the coordinator. This is why it is important to have a robust/strong zigbee mesh with plenty of devices that can repeat.
Also different repeaters have varying amounts of RAM available to support the number of devices that they can repeat for. I've blown up a section of the map and pasted that below. Of the three repeaters shown, one repeats for 7 end-devices, a second for 2, while the third repeats for just a single device. This difference either reflects proximity of the repeater to end-devices, or the repeater's capacity to repeat.

Thank you very much for your work, what plugs do you recommend to make my mesh stronger? I have a xiaomi but it does not make me a repeater, instead today I got an ikea plug and if they connect to it, the bad thing is that it is usb, so I am looking for a plug that has a plug outlet, not usb
If Innr plugs are available in Spain, I recommend those for sure. These are the plugs that I am referring to:
https://www.innr.com/es/producto/smart-plug-2300w-sp120/
They are zigbee 3.0, can be used as outlets in the EU, and also make good repeaters.
Yes, it is in amazon, it costs 25 euros, I'll take one to test, do you have the driver?
Works fine with the built-in zigbee outlet driver.

these should work fine with the inbuilt generic zigbee outlet driver.

I have a friend who has this plug, does it serve as a repeater? Does it have a driver or is it the generic one?
It probably does. But you'll have to verify that independently.
Many, but not all, Tuya devices use non-standard zigbee clusters. So the likelihood is high that it will need a custom driver.
That's probably my case: I just bougth two Tuya Zigbee water/gas valves and I can't make them answer to commands. I tried the recommeded (Sinope Water valve) and the "Zigbee - Tuya valve" drivers to no avail.
Here I go again ... learning on how to implement a Zigbee driver.
EDIT: The valve is like this one

Beautiful, just beautiful

a question which usb is that which acts as a repeater? It works well?
In my experience, both the dedicated USB repeaters I’ve used work better than other devices. The one I’m using currently is the Tuya usb repeater.

Dude you have a shitload of zigbee devices!!! LOL (Also wish I had known previously you had those iris v3 sensors for sale)

Those are just the ones that don’t work well with Hubitat. The rest (~50-60) are directly Hubitat-controlled, I’m slowly decreasing my zwave devices.

I havent had any issues with the v2 or v3 sensors (though I only have one v3)

Sorry - I meant the devices in the map that I pasted above. My Iris devices work very well with Hubitat.
