I’v tested 4.0.2 for 10 days now. At first attempt got same error @DaveCush77, but with second attempt it worked instantly without errors or warnings. For me it helped to login to the SEMS portal and do a forced logout (just click on ‘logout’) to make sure there were no concurrent sessions.
Since then it worked perfect, except for some time a few days ago, when the SEMS-portal itself experienced login-issues. The tile gave a warning and did not show any readings. The app/tile recovered itself after a while.
Measurements from insights are in line with the figures in the SEMS portal, so that’s ok. I’ve made some flows based on the readings (some lights on/off and notice of daily revenue).
I only have 1 converter, so not been able to test the situation with multiple converters in 1 account.
Except for the issues with the initial pairing, I think it is stable enough for release ?
Keep up the good work @Diederik !
