Wemos D1 Mini

What happened?

The payload of the current and power contain a space before the number if they are one digit before the decimal point. The payload for 1.0 A is " 1.0" instead of "1.0" The postprocessing OpenHAB item can't resolve the " 1.0" to a number: "2024-02-15 21:37:00.350 [WARN ] [ab.binding.mqtt.generic.ChannelState] - Incoming payload ' 0.0' not supported by type 'NumberValue'"

Screenshots / Fotos

Here the power is frozen to 2 digits before the comma 10.6 because the payload "10.6" can be converted. Values under 10.0 W can't be processed so OpenHAB item still shows 10.6 W besides being dark outside and should be 0.0 W.

I stumbled on the same issue. I susspect it is due to the ussage of dtostrf(bms.get.packCurrent, 4, 1, msgBuffer)); which will generate 4 charachter long strings minimum, however small numbers (0.0 ... 9,9) only have three characters, therfore a leading space will be added.
