I needed to add my Victron devices to mycontroller v1, so I've created a Esphome device that includes the Victrons and 2 Mopeka Tank Pro devices, all via BLE Advertisement Playing around with the topics, I have been able to declare a node name/id for each of these BLE devices. each BLE device has a node name/id, childs name/id. sensor example: sensor: ---------------------------------------------------------- Victron IP22 ---------------------------------------------------------- platform: victron_ble victron_ble_id: victron_ip22 name: "mains_charger_voltage" id: mains_charger_voltage type: BATTERY_VOLTAGE state_topic: "${mys_prefix}/${mys_gateway}/${node_victron_ip22}/${child_victron_voltage}/${C_SET}/${mys_ack}/${V_VOLTAGE}" on mycontroller I've created a mysensors mqtt virtual gateway, and voila'. from now on I can use Esphome to create other nodes, also in separate devices. I just need to keep track of the used node ids, that must be static. Node and sensors presentation is handled as well

@monte thank you for that one. Although almost 2.5 times the price it's cheaper than other European options.

For me personal, because MySensors has much more capabilities that most haven't used yet. So to me, I haven't found an alternative that comes close to MySensors. The only thing is. For the easy stuff you don't have to program at all when using esp with HA. But that goes over Wifi and to me that is a No-no.
