my 2nd smart mppt acts weird

Describe the bug

Hi, I have 2 victron mppt smart solar devices in my van - and both did work with BLE integration without issues for last months

• since ~ 2 weeks the one which is not so often used (my foldable panel) has a weird behavious
• when no solar power is coming in it looks normal and shows all values (0W power, 0A current,...)
• whenever i connnect my foldable panel and power is coming in suddenly all entities show UNAVAILABLE
• tried already to remove the whole device and re-install - no change
• the other mppt controller works without issues

any ideas ?

Have you tried bringing the device running HA closer to the MPPT? Could be the connection of the solar panel is attenuating the BT signal such that the device cannot be communicated with by the HA host BT.

During full noon sunshine, I get sporadic data...the Sun is disrupting the RF of BT just enough....once the Sun has passed over head everything resumes as normal. My Victron shunt is the most affected. It has notoriously weak BT power.

hmmm ... it worked like a breeze for the last 6 month .. and stopped suddenly with this weird behaviour => did not change anything physically in the setup

• and in addition it seems to have perfect connection when there is no solar power coming in
• and once power is on the panels it gets unavailable

another update on my issue:

• just tested again and when no solar panel is connected the appt HA device shoes correctly 6 entities with correct values (zero power, actual battery voltage,....)
• when I connect the panel it does not change / recognize it and continue to show as if no panel is connect
• and when I reload the victron ble I tegration for this device it flips back to "unavailable" for all values

on my victron connect app both mppts show correct values

maybe I shall try to reset the pin to get new key and retry
