kWh resolution - molelightn - 12-30-2025
Hi,
in the modbus specifiaction from N30 it is mentioned that Energy Sensor from BL0910 has a resolution of 1kWh only.
Is there any way to get a more accurat reading? For power circuits with low consumption it is misleading to see 0kWh consumption on end of day.
Does the BL0910 has a possibility to report for example 0,1kWh as resolution for Energy Consumption?
Thank you.

BL0910 only can use by 1KWH, can't use 0.1KWH.
about consumption data bug, we will update firmware soon.

1: update ARM CPU by USB-RS485 adapter, how to download firmware , see here: https://www.kincony.com/forum/showthread.php?tid=8863
2: update KCS v3.18.2, how to download firmware , see here: https://www.kincony.com/forum/showthread.php?tid=8864
3: if your energy data is a very large number, first time, please use the new PC software to clear to 0. here is PC monitor software: https://www.kincony.com/forum/showthread.php?tid=8406 just download newest version: APPV1.0.25.1231 https://www.kincony.com/forum/attachment.php?aid=8886

Can't you fix this with software? For example, in ESHPhome config integration sensor rather than using BL0910 hardware for kWh resolution?

BL0910 => Hardware solution => resolution limited to 1kWh
ESPHhome /kincony => software sollution => has current, Voltage and time => Resolution possible 0.01kWh

Can you change example ESPHhome config to include this and/or update KCS software for better resolution?
I think i can do it in ESP home, but maybe this is usefull for all users?

after China New Year holidays , we will check it.
RE: kWh resolution - Painy - 02-17-2026
Thank you.
Have a great newyear !
RE: kWh resolution - admin - 02-18-2026
The calculation of electrical energy is achieved by integrating the BL0910 chip to obtain a count value, which is 1KWH units. There is no way to change it.

Completly useless this 1kWh resolution for home usage, will take forever to get a reading. More suitable if you have +100A loads.
Waisted a lot of money for someting what looked nice on paper, next time add the specs and resolutions so we know before we buy.
