                       (crit = +88.8°C)

but in home assistant I only see (related to Corsair PSU):

Corsair MP600 PRO Composite 34.85 °C
Corsair MP600 PRO Temp1 Alarm OK
Hardware Sensor Corsairpsu Current 12V 2,000 A (wrong separator)
Hardware Sensor Corsairpsu Fan Rpm 0 rpm
Hardware Sensor Corsairpsu Power 3.3V 2,000W (wrong separator)
Hardware Sensor Corsairpsu Voltage 3.3V 3.281 V

Despite the 12v Current and 3.3v Power have wrong separator (should be '.' instead of ','), I cannot see all the other values like total power that is interesting for me.

Thank you for the fantastic job done so far!

After some time all sensors become available, only the wrong separators persist.

Hey thanks for trying out Go Hass Agent and reporting this issue!

I believe the issue here is that Go Hass Agent is sending the raw sensor data without any chip-dependent scaling/transformation. If you are comparing the values to, say, the output of sensors from lm-sensors, there will be discrepancies; lm-sensors has a database of chips with scaling/transformation information for their values and applies those as required before displaying the values.

So I'm guessing that for this chip, those current and power values should be scaled down by 1000 as per the lm-sensors database. So the separator is correct but the value is wrong, it's 1000x too high :)

I've been meaning to look into how I can parse/use the lm-sensors database before sending sensor values. But the format of the lm-sensors database is, somewhat "esoteric"...

Until I can decipher the format or otherwise use it, a workaround would be to create a template sensor that scales/transforms any values as appropriate. In most cases, it's probably easy to just compare the values between lm-sensors and Go Hass Agent as most sensors are probably just some scale factor (a few do have some formula transformations).

I'll leave this issue open to track that I need to look into this and I'll update it when I get the chance to apply a fix.

Cheers!
