Hi guys It would be great at create a new Sketch and put in Github: that handles many ds1820Bs on the latest V2 emonTH. Or at least - because want to use an emonTH to measure many temperatures, then other people may well want to, also! There are sketches for V1 to do that - but not for V2. I ha…

[image] stephen: if you want you could use something based on my sketch for the ESP That looks really useful and really neat way of referencing the different sensors. What boards do you use it on and what are the physical connections.

hi Brian I used it on about 10 different brands of ESPs. depending on the ESP you may or may not need 10k resistor the ESP i usually use are wemosd1,wemos mini, NodeMcu, esptoy or generic ESP it would be D4 (gpio 2) on esp for onewire and positive and negative where ever i can grab it… as t…

[image] cab123: WiFi can be unreliable for a persistent connection. I have made one that can map up to 10 DS18B20. Maybe you have a particularly bad environment or some flaky code. I’m sure I’m not alone in having an ESP8266 based system reporting many DS18B20s without a hitch. In my case for…

[image] Bramco: The emonTX could certainly manage the number of sensors. The number of sensors isn’t a problem with the emonTH, its the wireless transmission part of the hardware which could be a problem if there are several emonTH units all trying to “talk” at the same time. The ESP8266 uni…

How about this for an idea for the software/hardware: Using Veroboard or similar, make a pluggable bus - 14 - 3 pin sockets all connected together and then connected to the emonTH Using the DIP switches on the emonTH, put it into “program mode” (perhaps both off?) Insert a SINGLE temp sensor into …

[image] stuart: The number of sensors isn’t a problem with the emonTH, its the wireless transmission part of the hardware which could be a problem if there are several emonTH units all trying to “talk” at the same time. Also agree on the RF transmissions as I said I’d get issues with just one! T…

Guys - you are all stars for putting in your knowledge into the middle - many thanks! Summarising: is this a fair summary? Robert said: don’t think the emonTH and radio is a viable solution any more. So that means I do need some other hardware in the mix… shame but not the end of the world. …

I think we’re all guessing in regard to the actual number of sensors and their disposition. When the requirement went from 1 emonTH with 14 sensors in one location to many with variable numbers of sensors attached, presumably in widely separated places, the problem got a whole lot more complicated. …

Hi Robert does this help: UK installation: in kent Underloor heating manifolds - 6 off are spread about 10-15m apart -all in one building. 2 x 14 sensors 2 x 10 sensors 2 x 6 sensors Boiler-room sensors 1 x 12 sensors (currently use 3 emonTH’s with 2 sensors each -works fine) ( boiler …

Hi Guys many thanks for all the insight shared here. Would anyone be able to quote me the cost and lead-time: to develop the firmware for consensus solution here - an ESP8266 based controller for 14 DS18B20 sensors. Private message me if you prefer Thanks in advance
