Send an array of ADC data

Vasilis Vlachoudis 15 Mar 2023, 20:14 last edited by

In my home automation (with mysensors + home assistant) I am monitoring the 3 phases of the house with CT current sensors and the emonlib, which works nicely.
I wanted from time to time to send a full waveform with mysensors, but I could not find out how to send an array of readings instead of a single entry. Is it possible to do it with mysensors?

I want to experiment making an AI to identify from the waveform the device that is consuming the power.

Hi @blackchart, Unfortunately, all devices are sold out. Further production is possible only when ordering more than 10 devices (in this case, I also can modify the device to suit your needs).

@NeverDie Thx for appreciating the work done. There will also be an open source part in the future. When and how extensive the open source part will be, remains to be seen. The release of certain information (block diagram, ..., in this post) is related to those open source parts. There are some OBD solutions, however most of them (in my experience) give back low frequency data put by the car manufacturer on the OBD-bus (CAN, ...). Therefore transients evolving directly from the battery could only be recorded if the manufacturer sends those data accordingly on the bus. Due to the small bandwidth(also because of other car data that have to be sent, ...), such battery data are sent more often once per second or less. Fast battery events (i.e. cranking events, ...) are therefore imperceptible. Unless the manufacturer processes the fast events and then sends them (once per second or less), which is very unlikely if the manufacturer does not market this feature itself. Third parties devices for high frequency sensing costs several hundreds dollars. In my experience, important battery states (especially the fast ones) are recorded by measuring and processing corresponding data directly on the battery. I agree with you about the limits related to the communication over Bluetooth. But i think Bluetooth 5.0 will improve a lot. However, WiFi will always remain an important option due to the high data throughput. The combination of both (BLE & WiFi), especially with regard to energy consumption, will gain in importance.

@pugho You can do a lot of customization in Domoticz like custom icons etc. Just browse the wiki and forum (and don't get distracted ;-))

In general, yes, the MySensors framework (library?) should support FOTA a couple different ways (read more at link). Were you aware of this, or is there some problem with your particular hardware? @NielBierman said in FOTA possibilities for remote sensor network: Raspberry pi I don't know yet whether you even need to change your gateway from microcontroller (uC) to Single Board Computer (SBC) or not. However if you do (or are looking for a controller, or whatever), by all means, please do yourself (and all of us) a favor and do a little more research as there are lots of better options out there for SBC nowadays, than RPi! For me, uC have been fine for gateway although I do use some SBC for controllers, MQTT broker, and various other GNU/Linux based servers/services and they are wonderful for that. But perhaps your needs are different from mine.
