I have a Devolo powerline which -unfortunately- requires regular restarts (every 2-3 days) or it acts up.
I have not found an existing way to control them with HA so i have to go the configuration page and press restart whenever i see that the network is slow.
The admin page looks like this and does not require a password:
Yes, I bought the devolo as it was supposed to be the best but after 2-3 months it needed to be rebooted very often, so I went the safe way, I took it back to the shop and got a refund. Then wired ethernet and never had to bother again.
When I posted it, I was thinking perhaps HA could “visit” the config site and run some Javascript to replicate the reboot click. But I didn’t get lucky
Some Devolo PLC devices are added in the recent version of HA.
I don’t know if there is any support to restart the PLC devices from HA. If it is possible, you could add script to HA to restart PLC devices every 2 months.
PS Update 13 dec:
From devolo-plc-api 0.7.0 can restart devices. For now the integration has version 0.6.3.
Any plans to bring a reset button to Home Assistant for devolo Home Network? I need to reset two devolo 1200+ Wifi Adapters quite regulary (everytime the main coordinator changes) and would love to do it via HA.
