F3800 set up failing

[LouPaloma]

I'm running a F3800 with firmware version 2.7.2. I have successfully added the device, but no sensors are being created. Reloading the integration produces the same errors as noted in the log snippet below. Perhaps exception handling is too coarse grained such that a single failure kills the entire process?

This is a known issue #28 #47 and is addressed in v3.7.0 Beta 1. Please let me know if the issue is still present in the pre-release.

wow... just wow. I decide to try to connect my F3800 Plus this morning and I stumbled onto this... and it just works with 3.7.0 beta 1.

One thing it does not seem to relay is the total capacity and the expansion battery status. Do you know if it's possible to do that ?

[mboisson]

I confirm that it controls the AC output switch. I am not sure if it controls the DC output switch, as I do not have anything plugged in DC and if I switch it on, it switches back off (maybe because nothing is plugged in).

Do you think it would be possible to control the max generator input setting on the F3800+ ? That's a setting we have in the Anker app.

I can confirm that my F3800 is now able to connect using the beta.1 I'm deferring closing the issue in case you want it for tracking until the next release candidate.

Its possible but the command to set the charge power for that model is unknown, it can be determined by using the app decoding process or its possible it uses the same command as the F2600.
