Hi to all!!
I’m tunning my home setup, and i want to add a “minimal” backup HA device (beaglebone black, like a elemental rpi), to keep running critical services, i.e. during a power leakage.
I have a Ubuntu running main instance of HA, Frigate, etc. in a phisical i7 server, with a UPS. This UPS supports the network stuff (router, 5g, other non critical servers, etc), that impacts on UPS backup time avalable. For now, i have some automations thats power off all non critical systems when leakage time exceeds more than 3 min. But i want to improve UPS durarion as long as possible. If power downs, mains and all non critical will power down, and beagle/rpi must assume minimal services (less power consumption, more backup time), like security, and this means, stay connected to battery powered ZBridge at same time, same zigbee Network, same devices, without servers pissing each other. I need to keep motion, door sensors, and some zigbee security stuff running without interventions or delays. When power comes back, wake on lan, and go.
Keeping this in mind, and back to post title, you can easy guess that i want to. As Tasmota docs says, Sonoff Zbridge Pro must supports two tcp concurrent connections. I want to have main HA server running connected to ZBP (i use ZHA), and the beaglebone/rpi minimal HA instance, connected to ZBP too, both always at same time.
But …
I’ve been tested yet, and when second tcp client connected to bridge, main HA ZHA integration starts to be unavaliable, sensors disconnects…
If disconnects second HA, mains (integration) turns avaliable again after 2 or 3 min, but some sensors takes a long time to appears back online again. On security appliances, this is too much time to wait.
Needs to setup two tcp rules, and start each one on diferentt ports? How i can do It?
All aportations are welcome. ZBP are on latest Tasmota, and ZNP CC chip flashed with latest firmware too.
Thanks in advance. And sorry for my english.
