LOCAL IS FREE. REMOTE IS PRO.

Stay close.
Even when you’re away.

Pick a tested touch display or a screenless ESP32 profile. Put the gateway within Bluetooth range of your compatible battery packs. It sends readings over your Wi-Fi. Open each device to check its exact board and firmware availability.

Home Wi-Fi · free

A compatible MultiBMS app can show your gateway batteries on the same local network without a Pro subscription.

Remote access · Pro

Paid Pro routes battery readings through our server, encrypted in transit, so you can check them in the app away from home. See availability and requirements ↗

Hardware is purchased separately. Board revisions and firmware targets matter. Community cases have not been fit-tested by MultiBMS.
