Is there a guest or engineer access for my installer, other than sharing my username and password?

For customers who go with Pylontech batteries, monitoring them remotely by the solar company in any level of detail is near impossible. I think it's the sort of device they would want to add to their systems. However, I cannot see any sort of guest or engineering access, other than sharing my username and password with them. They monitor everything else remotely to pick up problems early and provide a health report annually, so this could include the batteries in the future. Any plans to interest the installers too?
