Pimatic max plugin extension

---

Hey guys,

I have made some rules to get informed via telegram if a battery is not ok. I have seen that this only available for the heating thermostats. But the window contacts and wall thermostats send their battery status too. I think it is time for an update to get more battery infos from max devices

I still need the battery status please. Who has writen the plugin?

maybe @mwittig can help or @georg90 ?!
