cwr Posted November 6, 2022 Share Posted November 6, 2022 With my heating system now operation I'm eager to get a data logger on it to see how it's performing and get it set up. Just need a data logger with about 4 channels... I've used Pico hardware in the past, but the price of these is somewhat excessive for all I need, so looking for a more cost effect alternatives. I know others on here have made their own loggers, which I'd love to do but genuinely don't have the time right now to learn how to. Maybe someday. A couple of options include these: https://www.ebay.co.uk/itm/115424989748 https://www.amazon.co.uk/Instruments-Channel-Thermometer-Thermocouple-Temperature-Main-Unit-88598/dp/B00M9Z3JJ8/?_encoding=UTF8&pd_rd_w=GsnH3&content-id=amzn1.sym.31c9090c-9b65-4f91-bf37-04dd92281172&pf_rd_p=31c9090c-9b65-4f91-bf37-04dd92281172&pf_rd_r=XK0SMPSNAWYRM7Z4QR67&pd_rd_wg=RjsLH&pd_rd_r=27d9a663-062f-439f-abf8-d542a29b5631&ref_=pd_gw_ci_mcx_mi Has anyone any experience of either f these, or recommendations of other options?

Radian Posted November 6, 2022 Share Posted November 6, 2022 I'm slightly more attracted to the Latvian one on ebay. Fairly low risk financially, although you'd need to do a bit of coding to automate the data collection. Maybe a macro in Excell or something in node-red.

There was a time I had no idea how to make one. A DS18B20 based temperature logger was the second project I did. The advantage of making your own is that code is easily available (could post mine up) and if you use a Raspberry Pi W of some sort, you have bluetooth and wifi built in.

Getting your hands on a Raspberry Pi is a problem at the moment. March 2023 is the earliest at the moment. Link to comment Share on other sites More sharing options...
cwr Posted November 30, 2022 Author Share Posted November 30, 2022 Thanks for the replies folks. So the eBay one would need coding? I can deal with taking data from a .csv file fine but just don't have the time right now to get into programming. Tempted tho to buy a couple of raspberry pi's for the future. In the meantime, I've found these: https://www.ebay.co.uk/itm/272131903720 Got a couple order to see what they are like. Link to comment Share on other sites More sharing options...

They've a new version which can take an SD card for simpler data transfer. It also appears to include the Bluetooth module. Works out around £75 incl. VAT and delivery for an 8Ch temp logger. https://www.ebay.com/itm/115695655888 2 Link to comment Share on other sites More sharing options...

Funny coincidence, today I hooked up a Raspberry Pi with a pair of 1-wire sensors to make a radiator balancing kit. 8 sensors would be equally do-able: This one is wirelessly sending the readings over MQTT to a client app on my phone for the display. Will be strapping the Pi to a USB battery bank for moving it from rad to rad. Link to comment Share on other sites More sharing options...

I must get around to charging up my old solar powered 5V battery banks, I am sure I can find the box they have been hiding in for the last 5 years.

I would not use it for anything serious, but for a cheap, secure, file transfer, I don't have a problem with it. Link to comment Share on other sites More sharing options...

A battery backup hat (PiHut has few) might also be useful as well as a strip board hat if you want to bring all of your OW devices back to a central connection board Link to comment Share on other sites More sharing options...
