GR2P-W/S/L Atorch CB2S firmware modification options and compatibility

I hid Zamel somewhere, very effectively .

The Chinese, on the other hand, looks like this:

I have separated from
Control and monitoring of mains voltage with F&F

It is most likely to be TuyaMCU , but it is still worth checking that there are paths going from RX1 and TX1 of the CB2S to the microcontroller:
.
If so, according to the tutorial:
TuyaMCU flashing, installation and configuration guide - configure dpID for Home Assistant .
I would also try performing this (before flashing):
Extract DpIDs for TUYA MCU devices .
Then changing the firmware as here (2MB backup first):
.
Then let us know, but analogously as in the tutorial or as here:
Advanced energy meter/thermostat with LCD Atorch S1TW-FR - cloudless operation .

If you undertake it, it's unlikely there should be any problems. So far every Tuya device I have encountered , as long as it has a display, is based on the TuyaMCU.

It's going to be hard to get started because iot.tuya.com won't let me log in. Despite giving a new password via the "forgot password" function, it doesn't accept it, so I can't log in either.

If I change the firmware to Tasmota, will I have to run some kind of home server to support it?

I gave a new password and logged in after the mentioned dpID last on 24.11.2024 and it worked, but maybe try a new account?

Tasmota only runs on ESP, here you can upload my "Tasmota style" firmware and compatible with its JSON format, running on many different platforms - link .

As with Tasmota, the device will be accessible via IP address locally, inside your LAN. It will also be able to be paired with Home Assistant or other services. If you want to have it accessible from all over the world, you'll need to either have a public IP and expose it to the world, e.g. HA, or get some sort of MQTT service or something from outside.

If it's enough that the device is accessible locally then you don't need any server, either on the LAN or on the internet.

Is it capable of FTPing data and sending email notifications on its own? Because that's all I need - that in addition to showing the current voltage and power consumed on the display, it sends to FTP the values measured at a set interval (let's say a reading every minute, and a summary report at a given hour once a day) and, in the event of exceeding the set values, sends an e-mail with the voltage and/or power value read at that moment.
