This problem relates to several different Cerbo installations, including my own in my house, and three other installations I have made for friends locally. Common to all is a set up with Cerbo set to home WiFi network to connect with Victron VRM. In the case of my own home, the router is 50cm away from the Cerbo, so no question of weak signal. In all the cases, the Cerbo shows more than 55% signal strength from the WiFi.
The problem is that the Cerbo occasionally disconnects from the home WiFi and will not reconnect. In the case of my home system, it has been running perfectly for over a year, then one day, it disconnects and refuses to reconnect, despite strong WiFi signal. There have been times when the router has been turned off and back on again, and the Cerbo auto-detects and connects. But on rare occasions, Cerbo disconnects and fails to reconnect even though the WiFi signal is strong
Solution has been to connect a computer or phone to the Cerbo WiFi, go into settings and turn off and on the WiFi connection setting, it then finds the WiFi and connects again.
Currently, I am not in the area, and four systems i have installed all seem to have disconnected themselves and refuse to reconnect all about the same time. This in itself is curious?
Cerbo is a pricey piece of kit for what it is (could do similar with an SBC for a fraction of the cost) and it would be really good if I did not have to drive around to several installations to reconnect them to the internet every few months. Does Victron have a reliable WiFi device that could overcome this issue. Obviously its not the home WiFi because this is common problem to several different installations, common denominator is the Cerbo
