Ok, so I want to give my experience with parts from BSEED, namely
- (~10x) zigbee dimmer switch TS0601_dimmer (https://www.aliexpress.com/item/1005003475686409.html)
- (1-2x) zigbee 1 & 2 gang switch TS0002, TS0001
- (2x) 1 gang 2 way (dumb) mechanical switch (https://www.aliexpress.com/item/1005003350992356.html)
- 1 gang 2 way (dumb) dimmer switch (https://www.aliexpress.com/item/1005004072707913.html)
At first, why did I buy these - if you have a panel with multiple switches / sockets, and you don’t want and/or can remodel it to multi-gang switches, then this is (was ~year ago) the only option to have a nice uniform (European) panel with up to 5 smart (zigbee) units (we have up to 4 in our house). Yes, I don’t like idea of trying to align several independent switches/sockets next to each other.
I start with what I like about these units:
- you can create a panel of up to 5 units
- you can combine switches with other sockets (power, signal, …), and still keep reasonably similar design
- zigbee works reliably
- dimmers can set min/max brightness (255 steps)
- mechanical quality is OK (I have no complains)
- dummy 2-way switches can be coupled with zigbee dimmer (or switch), I use TuYa TS110E_1gang_1
What I don’t like I will split to 2 sections. Lets start with mainly electronic quality issues:
- each dimmer unit has coil whine, albeit most of them are relatively quiet and inaudible once the (glass) cover plate is put on
- I have at least dimmer 2 units (out of ~10) with strong high pitch coil whine that can be heard from up to ~2m
- another unit is having some kind of coil “rattling”, not sure yet if it can be heard when covered (the coil whine of other units may be beating this)
- I think all dimmer units don’t properly stabilize the power & most of our smart light-bulbs (Philips 8718699688820, Ledvance 4058075208391, I think also Innr RS 227 T) are more-or-less occasionally flickering, especially during the problematic hours (sunset, early night) - I didn’t have this issue with previous dumb dimmers
- power wires screws are soft copper, so you need to be careful when tightening
- attached wall housing screws are not compatible with EU thread
- EU wall housing screw heads are too small - they go through the openings of the metal holder → I use M4 washers
I need to replace 2-3 units (but can’t get to it for time reasons…)
Last, features that I miss and things I don’t like:
- no zigbee direct binding (or zigbee 2 way switch) → for me relevant mainly for 2-way switches if you want them to work in case your network is down
- touch panel - only small circles on the glass are touch sensitive. This is not practical/ergonomic - tricky to touch in some situations (full hands, from behind the corner…) → Make the whole glass touch sensitive / split it to parts for dimmer/multi-gang switches.
- no OTA updates (hopefully will never be needed)
- not possible to use dimmer as “value changer” without adjusting the output power (do smth as Aqara H1 switch that allows to decouple the switch from relay)
- basic functionality only (no power meter, temperature, humidity,…)
- blue backlight LED can’t be switched off (at least not with zigbee2mqtt, homeassistant)
- the dumb touch dimmer switch can’t be coupled to zigbee switch unit → need to use mechanical switch (with less sleek design)
