Home batteries and your Wi-Fi
Storage systems that report home constantly.
What this kit needs from a network
Home battery gateway that reports constantly and controls charging against tariff times.
- Bands
- 2.4 GHz, with Ethernet on most systems — use the cable.
- How it's found on the network
- Cloud, plus local control on some systems.
- Background discovery traffic
- Low.
- Guest networks
- Setup fails.
- Separate IoT network (VLAN)
- Fine on an IoT network if the app still reaches it.
Setting it up
- • Wire it. Battery systems make tariff decisions and should not depend on Wi-Fi.
- • Confirm it reconnects after a power cut.
- • Stand next to your router while you set it up, then move the gadget to where it lives.
- • Put your phone on the 2.4 GHz network name for the setup, or use one name for both bands so the phone can follow.
- • If your router splits bands into two names, turn the 5 GHz one off for five minutes rather than fighting it.
- • Turn mobile data off on your phone during setup — some apps quietly use it and never find the gadget.
Mesh considerations
- • A mesh box with an Ethernet port next to the battery is the tidy answer.
Router requirements
- • A wired run to the battery location where possible
The kit we've checked
- Tesla Powerwall 70/100
Keeps storing and releasing power without the internet, but you lose the app view and cheap-rate scheduling when Wi-Fi drops.
Most common complaint: App stops showing today's solar and battery figures after a router change.
