In my testing, I found that this would result in the Sonoff appearing to accept the upload of the new firmware, but a strange checksum error would occur in the flash memory and it wouldn’t boot properly afterwards. The common process for putting a Sonoff into bootloader mode is to hold the GPIO0 pin low (ie: to GND) while powering-up the board. It can be done if you have the equipment and ability to make soldered connections to very tiny parts on the PCB, and this particular board also seems to have some strange requirements to force it into bootloader mode. However, out of all the Sonoff models that have been released this is perhaps the most difficult one to re-flash. Just like all other Sonoff models so far, the firmware on the T4EU1C can be replaced with alternative open-source firmware to add new features such as local-network operation, MQTT, etc. There is ongoing discussion about it on the SuperHouse Discord server so please join in. However, it’s possible that you won’t be able to use the touch sensor until this problem is solved. If you’re feeling lucky, you can give it a try. There are a few people collaborating right now to figure out why this happens. The rest of the Sonoff operates properly and it can be controlled by WiFi, but the touch sensor doesn’t work. It worked for me, but many other people have problems with the touch switch even when Tasmota is installed correctly. WARNING: There are problems running Tasmota on this particular model. The bottom PCB is the high-voltage mains board, which includes a 12V-output mains power supply, and a relay and Triac for controlling the active output to the load: Re-flashing the firmware with Tasmota

The top PCB is the low-voltage logic board, which includes the processor, WiFi antenna, 3.3V voltage regulator, touch sensor pad and driver IC, and the programming header: The T4EU1C consists of two PCBs joined together by an 8-way header. It operates by drawing a small amount of power through the light even when the light is turned off, so that it can run its own electronics. The Sonoff T4EU1C is a no-neutral smart light switch with WiFi, so it only needs the active-in and active-out connections that are already found at most light switch locations. Smart light switches that are designed to be installed in place of existing switches and don’t require a neutral connection are generally called “no-neutral” switches. With only the active wiring going to the light switch, it can be very difficult to replace existing switches with smart switches.īuilding codes in many countries now require that all light switches must have a neutral connection, but this is a recent change so most existing houses don’t have a neutral wire at the switches. This works well with passive switches, but most smart light switches need a neutral connection to power their own electronics. The active comes down through the wall to the light switch, and then the output from the switch goes back up the wall to the active side of the light fitting. Traditional house wiring has an active and a neutral that meander around the ceiling to each light location, with the neutral connected directly to the light.

#Install coolterm download

Download the zipped folder from the link above, right click and extract here.

These are the steps I followed to make it run on Ubuntu Linux If you really need it, they can easily be installed. Any hold backs I should know?ĬoolTerm has one disadvantage though: it requires installation of some 32-bit compatibility libraries on a 64-bit machine. CoolTerm Serial terminal has been developed by Roger Meier in Xojo. It has linux version can be downloaded from Author's Website. Coolterm Serial Terminal is the best serial terminal i have used for personal.
