Re: WheelTop EDS TX Full Wireless Groupset (Chinese SRAM) Some findings about derailleur.
Looks like the FD battery is removable, but there is sealant between the battery and the derailleur body (pic 1) and I found a report of water ingress through that gap between the battery and body (pic 2). And some device insides as a bonus.
Additionally, there is a report of PCB corrosion caused by condensation due to temperature changes (dew point).

Re: Having a problem with Wheeltop EDS TX

I'm glad I found this site, it looks like the place to hopefully get some help with the issue without kneejerk responses.
I installed Hydraulic EDS TX on my bike 2 months ago, it was a bit finicky to set up but it's been perfect since then. Until yesterday. My rear derailleur has lost its mind. It no longer shifts and sometimes disconnects from the app before I can even get to the debugging menu. The red charging light was flashing for hours yesterday and is on today without the charging cable connected. I believe everything is paired because all 4 components show up in the App and because I re-paired everything just in case. In the App it says it's in a different gear nearly everytime I look at it.
I'm kind of freaking out and after describing it I'm not feeling very hopeful. The manual is not helpful for any of this so I'm hoping someone might be able to offer some guidance. Is there a way to reset it completely? If it's not something I can fix myself does anyone know the best way to contact Wheeltop, I think I saw somewhere they have a Canadian office or distributor? I haven't looked yet but hopefully you can buy individual components now.
Thanks for any help you can offer. I guess it's always a bit of a gamble buying from AliExpress but in the end I know given how much stuff I buy I'm still way ahead.

I assume that your battery has shorted. Try to remove the battery and check if it continues flashing. Check the battery contacts and the contacts on the derailleur for any signs of oxidation (corrosion). Clean the contacts if necessary. Try charging the battery using a wall charger independently of the derailleur.

Here is the video on how to remove battery and prevent water ingress youtube.com/watch?v=-k5TzYEYwJg turn on subtitles auto translation.

In the attachments there is a video with a similar problem, do you have the same flashing?
