Tuya ZB range extender offline 2-4 days

Get Help Devices
1

I bought 2 of these Lincukoo (Tuya) thinking it may be helpful in my shed. There are 5 devices out there and I just wanted to make sure I had a good, strong signal. Sometimes a device will attach to the house and its LQI is poor then.

I have had a mini repeater (and 5 in the house) there with no issue so far.

I have tried 3 drivers and different power USB bricks but after 2-4 days each one goes offline until I reset the power.

At first I thought I just had a bad device but they both do it.

Thoughts?

Might need something with an external antenna. Like this:

That’s exactly the product I’m dealing with.

I’ve been skeptical of Sonoff stuff after a not-great experience with something from them a long time ago (I can’t even remember what now), but I’ve put a few of these usb plugs in service ~6 months ago, and they are very good repeaters…

I have 2 out in my detached garage ~60’ from my stucco house - one is in “turbo” mode and the other isn’t – both are absolute rock-star repeaters out there.

Sonoff devices have been solid for me. Their new water valve for outdoor hose bibs. And their extremely tiny power monitor, handles 16 amps!

I like that they use major Zigbee chips from TI & Silicon Labs, that usually follow standards

I will probably contact China and see if I can get a refund; they both drop off 2-3 days in.

I have 2 of the valves and they seem fine. One did come with a poorly installed gasket so I had to silicone the mating surfaces. They are labelled Tuya (driver Tuya Zigbee Valve) but the device info says SONOFF.

I’ll look at the Sonoff USB switch and see if I can get some LQI numbers from the web.

My mini repeater out there has 4 routing connections but only 44-100.

I have the same problem with ceratin of my Tuya tiny USB repeaters(CH 25), but others are always on.

2 very strong repeaters I have are both discontinued devices. The old Iris block plug (3210-L) with Zigbee/Zwave and the old Ikea Tradfri repeater. Maybe you can find on Ebay?
