The update of the plugin itself works fine for me. But als well for me the telegram rules in my testsystem gets deactivated. Seems the installation package is little bit different to the manual installation way. Today I have no time to get deeper into this. At the weekend I will find time for it.
@Dan: I made a test as well on node v8. This was working too. The long term test were done on v10. It was a system without previously installed telegram. But I create rules after the installation. One was sending messages every hour and the other one was reacting on received messages. Both rules works fine under node v8 and node v10.
EDIT: I deleted the plugin now completely from my test environment with is reachable remotely (node v8 base) and reinstalled it. Now the test rules are working again. I will give it a try in my productive system asap.
