Feit WiFi "Smart" Dimmer Switch (TYWE2S) #7052

Closed backcountrymountains closed 4 years ago

backcountrymountains commented 4 years ago

I bought a couple of Feit dimmer switches from Costco. They use the TYWE2S chip which is soldered to the main board.

I think the 3.3v, GND, RX and TX are accessible through the holes in the main board, but according to other write-ups of the TYWE2S, I need to connect GPIO0 to ground to enable flashing mode. I don't have access to the back of the TYWE2S without desoldering it. https://github.com/arendst/Tasmota/wiki/CE-Smart-Home---LA-WF3-Wifi-Plug-(TYWE2S)

Has anyone tried to use these? Any advice on flashing without desoldering?

How do I test it and get it working?

Thanks.

Did we find out the results of the tasmota configuration on the chat? If so, what was the results?

backcountrymountains commented 4 years ago

Got a Pi and did ota tuya convert. Worked out. Went with esp home but I've got flickering. Might try tasmota to get rid of flickering. Probably should've closed this issue, sorry.

mkormendy commented 4 years ago

I have this flashed with Tasmota, but the dimmer feature isn’t working correctly.

backcountrymountains commented 4 years ago

My esphome config is here: https://community.home-assistant.io/t/costco-feit-smart-dimmer-tuya-convert-tasmota/151390

Dimming works but flickers.

Somebody did it with tasmota there.

mkormendy commented 4 years ago

@backcountrymountains Yeah I followed those instructions with no luck.

carefulcomputer commented 4 years ago

this issue is closed. does it mean that it is working fine on new version of tasmota ?

danlat commented 4 years ago

See the home assistant forums link, this is working with latest Tasmota except for some missed hardware button status updates

tasmota is highly unstable. it stops responding randomly.

BlowOnFuel commented 4 years ago

I got few of those which also could not be flashed OTA with TuyaConvert.

I took off the TYWE2S with a heat gun and was successful at flashing the TYWE2S and reinstalling them after reloading the contacts. As there were no apparent traces/contacts under the TYWE2S, I tried poking a hole to gain access to GPIO0 but it still does not seem to enable flashing the ESP with the PCB is mounted on the mainboard. I suspect the TuyaMCU on TX/RX also prevents access to the lines for flashing.

Hope that helps.

carefulcomputer commented 4 years ago

i have given up this dimmer. replaced them with current dimmers. btw @BlowOnFuel , if you want to flash while it is on board, MCU needs to be disabled to flash tasmota. generally that is done by grounding the reset pin of MCU.

BlowOnFuel commented 4 years ago

With the gap between the PCBs, I doubt it is really an option to try to poking a hole to gain access to GPIO0 to flash without taking it off. Without OTA, I feel it is still easier to take the PCB off and flash it wired.

Thanks anyhow for the info about disabling the MCU.

Hope OTA will be back soon for these devices.

Any precisions on your alternate dimmers?

carefulcomputer commented 4 years ago

btw, don't hold your breath for OTA. seems like Tuya has really amped up it's defences.

other recent dimmers (treatlife, Martin Jerry) come with TYWE3S which has all pins exposed on sides and mostly well documented (regarding grounding MCU's reset pins) and all settings to make it work. I have from both brands and they work fine. Avoid other brands (gosund , meross). They have either non esp chip or non standard MCU (non-tuya) which gives several headaches.

BlowOnFuel commented 4 years ago

I would not have unsoldered the TYWE2S to flash them if I was holding my breath for OTA...

As dimmable bulbs seems awful behind smart Dimmers, I guess the way to go is to have smart bulbs driven through IP from smart dimmers instead of dimmable bulb hooked up to smart dimmers.

I guess I should be looking at dimmer for which I can get the long press or multi-buttons along with smart bulbs for more flexibility.

carefulcomputer commented 4 years ago

then your choices are severely limited. AFAIK that is possible only on MJ dimmers (that I know of) which doesn't use MCU to control dimmer. Most of other dimmers are controlled by MCU and use ESP only as wifi radio and you can't configure long press or multi-press (since buttons are not connected to esp gpio). you may/not like the looks of MJ dimmers though.

magimat commented 4 years ago

hey, I bough a pack of those FEIT dimmers today and even though it sucks that OTA is not working anymore, I was able to flash is using wired method quite easily:

https://community.smartthings.com/t/costco-cheap-feit-smart-dimmer-wifi/208142

at under 40$ CAD for 3 of those, I feel like it's really worth a few soldering :)

NorthernMan54 commented 3 years ago

I just recently acquired several of these as well, and I was amazed at how good the button's feel compared to the 'CE Smart Wifi Dimmers'. They also received a good WAF score when compared to the CE Smart ones.

The only negative feed I did receive was that the green LED's are too bright. Did anyone find a method to dim them a little bit?

PS I managed to nab some new old stock, and they were easily converted with Tuya Convert.
