Can you please design a universal analog device that takes any 0-5V analog input. In the app I would like to insert my own units, sensor description and maths .
This will make it very easy to add universal sensors of ANY kind as long as it works with 5V.
Forward to @Daniel_Zhan from SONOFF team since it’s a hardware product request.
A DC input product with the Dry contact output relay is on our roadmap. It is expected to be released in Q4.

Will it be able to monitor and display the analog input?
The SV device has all the hardware. I like the eWeLink app and wish they would update the Firmware for the Sonoff SV to allow us to use the GPIOs and ADC on the chip, as well as update eWeLink to support it. Note their are 3rd party apps that do this. But you have to do a lot of work to get it to work with eWelink.
If you don’t mind using Zigbee you could try looking at the GitHub page from Espressif and use their code, pretending to be a temperature sensor or something. I’ve seen evidence of Zigbee devices working on a Sonoff iHost. I expect they’d work on other Zigbee hubs too as long as you keep to Zigbee 3.0 specs.
An alternative would be to put tasmota on any device and connect to it over wifi with MQTT, but that requires a device to run MQTT on.
