I have 3 TRV in my house with external temperature sensors. All have fair to good signal but one temperature sensor in my bathroom. That is the furtest away from my M3 hub so I need a repeater.
So far I saw the Aqara Smart plug would be the cheapest/easiest to add:
Smart Plug EU - Aqara
But I’m not very familair to the M3 hub yet. Can you use the cheapest NON Aqara plug too? Or only Aqara?
Any other suggestions?
Aqara E1?
When I started, I had one m2 and a lot of the smart plugs to widen the signal, worked great for me with Aqara smart plug, and I ended up taking my Philips hue plugs away because there where more function in the Aqara plugs
What are you trying to say?
Aqara E1 is not a product?
One of the best way is to use Aqara hub m100 imo. It’s cheap and reliable.
Hi, a relay with neutral and a socket will probably be the cheapest option, but you can also buy an E1 hub and connect devices to it, this will be a new zigbee network, but in the aqara ecosystem you will not notice it.
I think the M100 and E1 hub are the same product?
Is a fair price yes, but the smart outlet is not much more and usefull for other things.
I use the THIRDREALITY smart plugs as repeaters. I was hoping that the Aqara FP1E would have been as well, but it is only and end device.
Hello,
I have had great success using these devices to firm up and extend my Zigbee network:
Aeotec Range Extender Zi - Zigbee Network Extender. This is all it does, but it does it very well. I have these placed near the physical periphery of my home and also where the network has trouble penetrating or going around some walls. I currently have 3.
The Third Reality nightlights are also good range extenders. I have 2 currently. They link floor to floor nicely.
Zigbee is a self-organizing mesh network. Reliability increases with the more routes you have from one device to another.
A Zigbee network visualization tool is very helpful in identifying peripheral devices and/or low quality routes in your network. I use the one that is included with the Home Assistant Zha integration

Oh, and Hue ceiling lights 
So you cán use other devices to extend the Aqara M3 zigbee network…
I have various smart plugs that I use to extend range. I really like the thirdreality motion night lights. The different color lights are great for different notifications
M100 is my recommendation
The Aqara M100? Isn’t that a hub, not a repeater?
I use a smart outlet/plug, using something that is just a repeater seems like a waste.
Anything zigbee & mains power should be good. Avoid light bulbs.
No. Must be an Aqara plug. Aqara uses a private Zigbee network. Plugs are cheap … buy a couple … strengthen your Aqara mesh network.
Great info. I Will get my hands on some plugs to boost my network! Thanks
It is, but also it configures as just one more item in your home zigbee network and act as signal extender.
Same as a G3 or G5 cameras would do
Can the Hub E1 act as a zigbee repeater? I thought it can work as either a hub or a wifi extender.
Aqara Smart plug is the best option by far
