I’ve almost got these working in the tuyalocal integration without re-flashing. I was able to control these offline, but still working through the re-initialisation after a power outage, which at the moment needs some manual work to get them communicating again.

Hi Steve - you need to make sure you’ve got the Series 1 detas… The newer Series 2 switches have a chip that can’t be flashed to Tasmota.
If you’ve got a Series 1 switch, this page was useful for getting going with flashing: DETA Grid Connect Smart Switch and Home Assistant – Hopefully Helpful Hints // Mike J McGuire
liminal, unfortunately the new BL20925, are no longer using a esp chip. I spent a good part of a day pulling one a part and trying to flash it. After removing the IC shield, I found it is not a ESP chip. They are now using a bk7231t, and from what I have found, these don’t seem to be compatible tasmota. You may be able to transplant the chip with a tywe2s, but these are around $10 each on alliexpress, so really not worth it. Picture attached.

Well that sucks!
Thanks for the info mate!
Three more BL20925 arrived and flashed with ESPHome with no probs, so there is still a bit of old stock floating around Melbourne.
Mine where bought in office works in Brisbane. Such a shame they can’t be modded.

I bought 2 in Sydney (Officeworks click&collect) last week and could tuya-convert them, ordered 6 more now. Fingers crossed…
Edit: Nope, no luck this time. The new ones come with a WB2S chip.

I was actually looking into this unit and reached out to my insurance company and they looked at the device and I have in writing from them there is no issues having this device installed.
I would like to know alternatives that have multi circuit monitoring at a similar price point or close.
I did see someone seems to have reverse engineered it to talk locally to a local mqtt server.
Hi @mikal can I ask where you purchased the Mercator Ikuu globes? They seem expensive, compared to other Zigbee globe brands.
I bought them from ceilingfansdirect.com.au – they’ve been really reliable. The 9W RGB ones are $40, which seems fair to me for something with an Australian electrical certification.
The similar globe from Brilliant Lighting, although they are WiFi are $17.95 from Office Works. But sadly they are not ZigBee.
Hi @kanga_who , I got this to work. Cheers Mate. I changed the actual commands a little bit but got there.

I actually like having more info automatically in Home assistant using SetOption19 1, works well and I can troubleshoot in an MQTT Viewer.
One issue I found was that if I used the code that gave me the speeds, Apple Home saw it as 4 switches, very weird. If I just use the speed numbers, it’s as it was before (Snaps to 33/66/100 percent for the 3 speeds).
One issue I have found is that if I set the speed in Apple Home it does not get updated in Home Assistant … Any suggestions?
EDIT: Actually same issue from the RF Remote, does not get the speed. Apple home sees every speed as 33%.
EDIT2: I can’t see the speed commands from the RF remote being shown in a MQTT browser, I swear this used to show up in the old code.
@HasQT Unfortunately that is a twin GPO but looking around the 3A site I did find a 1 gang switch module and Amazon.de have a 2 gang version. However it doesn’t seem to be available on their eBay or Amazon store. Also it’s not listed in the Blakadder database.
I will send them an email and see if will be available anytime soon.
Hello all.
How do you power your squillions of usb devices?
You know, the Chromecasts, the ESP’s, the hubs, the cameras etc etc.
Do you just mix/match all those usb wall warts you’ve accumulated and mash them into a powerboard?
Or do you have fancy multi-port chargers or usb powerboards?
I use a $5 4 port USB hub connected to an old phone charger on my test bench. It has run 4 ESP devices without issue.

In my network cabinet I’m running a 5 or 6 port multi USB brick, for a couple of Pi’s, Philips Hue Hub, and something else I can’t recall from my couch.
It works well - I use similar one when travelling as only need to take the relevant figure-8 cable.

The way a lot of the chargers are marketed is pretty shitty.
They give you the impression that each port can do the total max load.
Like this one for example.

I hard-wire all my 5V and 12V devices in my 19" rack to a Meanwell dual rail supply.
For remote devices spread all over the house I am slowly replacing 5V plug packs with electrical outlets that have USB outlets as well. The good ones aren’t cheap though.
