It enables you to backup your devices firmware and upload an alternative one (e.g. TUYA-CONVERT creates a fake update server environment for ESP8266/85 based tuya devices. TUYA-CONVERT was developed by Michael Steigerwald from the IT security company VTRUST () in collaboration with the techjournalists Merlin Schumacher, Pina Merkert, Andrijan Moecker and Jan Mahn at c't Magazine.

If not, we considered giving up with the power metering and just log when the plug is on and off. Here the question: is there a realiable smart plug, with power metering cababilities, that can be flashed OTA with tasmota and compliant with EU regulations? (we are based in Italy). Older models are ok, but Tuya is clearly changing direction, moving away from ESP82xx controllers so we can't create a business model based on that. We need to flash probably 1000 of such devices, it is not feasible to open them all, so OTA is a strong requirement. We have tested a few Tuya based smart plugs, but with the new firmware it was not possible to upgrade them OTA. It all sounds simple on paper, but we are struggling to find a suitable device. The end user will just have to plug the device in the smart plug, to press a button on the app and move on. The measurement have to be done by untrained people, so simplicity of use is a must.Īfter a bit of brainstorming we concluded that the solution could be to use a smart plug with power metering capabilities, flashed with Tasmota and coupled with a custom-built app. We have a project that requires to measure the power consumption of a device.
