ive used these with mysensors for several years now... they work great. Batteries last ages!

New to electronics and progamming.... hence excuse rather dumb nature of my query .. recently purchase the Devduino V2.2 OTA version and am trying to figure out if the device comes pre loaded with the arduino bootloader. ??

@michlb1982 A couple of things, you put the device to sleep so while it's asleep, it won't respond to the commands to change the relays. Since you are combining relays and sensors, you need to keep the unit awake and find a different way to send the sensor data occasionally. For the relay status, read the comments in the sketch. You are saving the relay state and then reading that on startup. You can eliminate all of that code and just set the relay to off in the setup section. Cheers Al

@zmatokan said in NModule: @Nca78 Are you still working on this pcbs? i think it would be great to add a version that supports HiLink 220ac->5dc module on powerboard. No I'm not working on NModules anymore, I have a few old nodes using atmega/nrf24 but I switched to NRF5 for "basic" nodes now, and to ESP32 for more "advanced" stuff. NModule was designed for beginner and simple/riskless use, so I don't think adding high voltage option is a great idea, it's better to use an external power supply and connect the output to the powerboard.

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.

In deep Sleep the cunsumption is below 19µA, but i have to send with PA_MAX. On some Windows the open/close frequency is verry high, so the battery is to fast emty. The CR2032 is good, but i want more "lifetime"

@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.
