VW E-up! Climatisation works randomly

Winter has come to Sweden and I want to use the OVMS module to climatize my car via the android app. To my disappointment I can not rely on it to work. The first time I climatize after a fresh restart of the module it generally works but if I try to repeat without restarting the result is unperdictable and usually it does not work. Anyone having the same experience? Suggestions for a workaround much appreciated. I can provide log from the web editor and a summary oft the module settings if anyone is interested in looking into my problem. Thank you /Lars
