My PV inverter sends floats with a negative exponent that cannot be parsed by openHAB 3.3:
2022-09-08 20:51:01.336 [WARN ] [ab.binding.mqtt.generic.ChannelState] - Incoming payload '5.605193857299268e-45' not supported by type 'NumberValue'
Am I missing something here or is this a bug?
Thanks for any insight!
Seems to be a limitation that exponent notation is only supported if you use a capital ‘E’. I tried it with
5.605193857299268E-45 and it was parsed correctly. Might be a candidate for a change request / issue in github.
edit: You could apply an incoming value transformation (e → E) to fix it, e.g.
Thanks @absalom for the explanation and the workaround.
Had the same thought applying a transformation on the channel, but you even provided the regex in your edit, thanks!
