Implement Default state when Projecter is without Power

[lord-drinkalot]

When the Projector is powered off and I reset my HA Instance, the Integration fails to start. And I cannot get it to work without powering on the PJ and resetting HA.

Maybe implement a ping if the IP is reachable, if not update with a "not connected" state and skip the rest.

that is definitely something I can do and a good catch. With the model I've got, I never ran into this issue as the projector has no problem responding to the connection test command when powered off.

We should have a catch for the "JVCConfigError" in the initialisation for the remote entity and output a Log error messsage instead if the connection fails. This way, the entity can still be created.

I appreciate the report. If you have the ability, could you please test with the base python library to answer the following (ensure homeassistant component is disabled):

• Projector initially powered off, go through the initialisation steps. Does this work?
• Projector initially powered on, go through initialisation steps, verify the connection (try a p.is_on()). Now power it off and try p.is_on() again. It should return the False. Does this work as expected?

EDIT: I just realised, you might be referring to "powered off" as in off at the wall, not just in standby. If this is the case, no need for the troubleshooting steps above and the initialisation error handling would fix this.

I am just concerned if some projectors don't respond to the nullcmd command when in standby.

[lord-drinkalot]

Correct, no Power at all, I use a APC PDU and control it with SNMP. So If I don't watch something, the outlet is disabled and the PJ is not in Standby.

If the PJ is in Standby then everything works as expected.

[bezmi]

This should work now.
