Hello there.
Recently bought some used SP1 V1 sensors. Can’t download software or confirm the license since you don’t have it on your new website. Already sent an email to suport@sunhou.se yesterday at midnight with all the data from who I purchased it, the key and the sensors.
Just passing here also to know if you respond to emails on the weekend, so I can know if I have to wait for response and/or when I can get attention in case of any inconvenients.
If I can get an answer today (saturday) would be great since I have time to test this things! 
Thanks!
