How to buy the right CGG1? #202

Open unaiur opened 2 years ago

unaiur commented 2 years ago

I have tried 4 times to buy the right CGG1 device in AliExpress but I have received 2 CGDK2 and 2 old CGG1 devices based on Nordic chip.

Can anybody share a link where I can buy the right version?

Thanks!

I ordered from that seller last month and received a 3 year old device with Nordic chip

Received 2 devices from Cleargrass store this week, both without battery and with Nordic chip. Identifies as "Qingping Temp RH M" but has Nordic UUID. Has the Qingping logo on the back. Waiting on 2 more from Mi Homes store, not holding my breath... Maybe they switched back to Nordic chip to keep hardware for M and new H version similar?

"Qingping Temp & RH M" has this certificate. But in reality, others are produced and sold. https://github.com/pvvx/ATC_MiThermometer/issues/41#issuecomment-812803456

I think they are cleaning up old inventory. The units I received 15 days ago from Mi Homes vendor were manufactured in 2019. @p5y Are your units from Cleargrass vendor also 3 year old?

Just checked, they are from 2022.1 IMG_20220325_175448

Received 2 more from Aliexpress Mi Homes store, they're the same batch as above. production date 2022.01, no battery, same packaging. It looks like it's going to be hard to get a Telink equipped version from now on, maybe we can add this to the wiki @pvvx?

I've just received three CGG1 thermometers from Aliexpress. They've turned out to be the CGG1-M 2022 variant with a production date of 2024.01. Flashing and configuring the custom firmware has worked fine.

I've bought from the following listing ("3pcs M version"): https://www.aliexpress.com/item/1005006203489017.html

I also bought one from Aliexpress, here is the listing: https://de.aliexpress.com/item/1005006203489017.html

Production date 2024.03 and flashing worked flawlessly. Maybe old stock is cleared now?
