Hi all, thanks for your reports and apologies that it took so long to respond!
Issue found, and fixed.
The issue was that since v3.60, in either all or some wireless tank sensor setups (= Mopeka), changes to the configuration settings were not stored properly.
So got lost after a reboot.
Fix is coming in v3.62~2 beta version. With a bit of luck still tonight. Would be great if you can then confirm that for all of you it works well - to make sure that there is not a second issue.
Thanks again, Matthijs
