Modbus scaling to float - Kilogica - 15.12.2021
Hello,
I'm trying to scale a 0.1 m3/h register to m3
Code:
{
"manufacturer": "DabPumps",
"description": "Evoplus Small_test",
"mapping":
[
{ "name": "Flusso Stimato",
"address": 220,
"type": "register",
"bus_datatype": "float16",
"value_multiplier": 0.1,
"writable": false,
"units": " m³/h"
}
]
}It keeps giving me 0.00, if I remove value_multiplier it reads pretty much 7...how could it be?
I know that probably it's a simple thing but I can't see where I'm wrong
Thank you!

Add "datatype": "int16"

False alarm, now it's reading good with the previous code.
I really don't know what the problem was, since yesterday it kept reading 0.00 until now.
Thank you for your help.
