I flashed sonoff-basic.bin tasmota file in some sonoff mini DIY devicers I have, but home assistant don’t discover any oif the devices. I read a lot about this, and seems my config is right (in fact, other tasmota devices, like some rgb bulbs were discovered fine) and it seems devices with tasmota’s sonoff-basic firmware aren’t auto discovered.
Sonoff mini devices have a 500k limitation, and I am not sure if I should use the update firmware option or which file should I download and flash, to avoid brick it…
Normally d/l / flash tasomta-minimal and then tasmota.bin. You won’r brick it if the new firmware is too large - the update will just fail. All sonoff devices are like that, not just the mini. When you upgrade the firmware, the 1Mb ram needs to be able to hold the old and new firmware in memory at the same time and only deletes the old one when the new one is successfully flashed.
All my sonoff mini’s use tasmota.bin. It is correct if you use the sonoff DIY method to flash them you first need to use tasmota-minimal.bin, but once they are on Tasmota you can upgrade to the normal tasmota.bin.
Have you ever upgraded Tasmota on any device? Unless you ‘roll your own’ Tasmota, you need to flash minimal first as per my above post. After you flash minimal, there will be enough free memory to flash the full bin file.
If you use the tasmota console, and both tasmota-minimal.bin and tasmota.bin are on the same location (https://thehackbox.org/tasmota/) it gets done automatically. I’ve upgraded more then 40 devices.
I really enabled SetOption19, but the device wasn’t discovered. I flashed old sonoff-basic file to my sonoff mini, so I can’t access to DIY method anymore…and I am not sure if sonoff-basic.bin is the same as tasmota-minimal.bin. To be sure… should I download last flash tasmota-mininal.bin file, and flash it from tasmota menu, and then upgrade to last tasmota.bin? Is this the right way?
Can you please help me? I flashed the sono mini with the tasmota minimal using the application for windows. It said it was successfully completed and the sonoff will reboot, but I could close the screen. After that my sonoff don’t give any signal of working. I saw that a YL named network show up…it is open…I connected to it but nothing happens…I don’t know how to do now. Please help me.
After reeding some answers here I flashed with the minimal.bin firmware and now I don’t know what to do. There is no Wifi AP named “tasmota_XXXXXX-####” (where XXXXXX is a string derived from the device’s MAC address and #### is a number) like as said in the Tasmota page.The only Wifi that showed up is named YL.
After I saw the wifi network was not created as I was thinking I read in the Tasmota page that the Minimal version allows intermediate OTA uploads to support larger versions and does NOT change any persistent parameter. This version should NOT be used for initial installation.
Please someone help me.
I don’t have FTDI board and I don’t know how to use it. Did I lost my sonoff mini?
I flashed it using the tool for windows that itead provided. It uses wifi and has a limit to 500kb. I used the minimal firmware because it was less than 500kb. I don’t have a serial connection. I saw in many videos that you can do by wifi, but they didn’t teach well in these videos.
I did that…but I flashed using the minimal.bin firmware. There is no tasmota_xxxx wifi network showing. There is only a YL named network and I don’t know what to do now. Can you help me? Please.
I have one lying here on my desk to. The only way to save it is flash it serially, one way is to solder some wires on those pads, but I only managed to solder the pads loose from the pcb
There seems to be another solution to flash it serially, using pogo pins, but for mine that is late already.
You need a ftdi board. But there are no holes to use dupont wires. So it’s either solder your jumper wires on the pads, or using pogo pins (connected to dupont wires)
