How to repeat presentation when using home-assistant with persistance false

[leonard]

I'am using home-assistant for a while and build some temperature sensors with mysensors.

With the default settings, home-assistant is caching the presentation and sensor values in a pickle file. This has the following downsides:

• when restarting home-assistant, old sensor values are beeing shown as new (just received)
• when changing a sketch, some added information does not update (or partly).

So I decided to turn off the persistence. Now I do have the problem, that nodes have to repeat their presentation when restarting home-assistant. I haven't got this working properly. Resetting the nodes fixes this issue, but that is not an solution.

I see two solutions

• repeat presentation (if necessary, nodes are battery powered)
• tweak home-assistant to do a more clever persistence

The more clever persistance would involve:

• discard old sensor values (or do not show them as new values...)
• allow sketch updates without limitations (details would have to be investigated)
• Allow to remove nodes that are not present any more (pickle file can not be edited easily).

Has anyone suggestions to solve this issues?

How can we send a I_PRESENT or I_REBOOT command using the HA / MySensors API? If there's a way, then an automation be be hard-coded to request each node to reboot.

Hello,

is someone find a way to send a I_PRESENT or I_REBOOT command using HA? or an other workaround to force node presentation when the persistant file is desactivated? (usefull after a HA reboot for instance)
