bad json payload

[costascontis]

i have found a weird bug(?) …using the original blakadder’s nspanel.be .When i change the thermostat’s setting for example from 19 to 20 i get at mqtt

{"NSPanel":{"ATCMode":0,"ATCExpect0":20}}

and everything is working ok parsing and transforming reading the number setpoint in openhab but when i set to 21 and only then i get

{"NSPanel":{"ATCMode":0,"ATCExpect0":21}B}}

This is only happening with “21” value…

I found the same... I found a little solution. Please comment....

I have a similar issue with a bad json payload, but on scene buttons. I have 3 scene buttons, but when I press on the last button, the last '}' is doubled. Press on the second button gives me: {"id":"2"} Press on the third button gives me: {"id":"3"}}
