@Yveaux I have 34 of 80k RAM used for this sketch, so 128 bytes looks like "a bit more".
You can not use progmem with ESP and mysensors now because PSTR redefined as PSTR(x) (x) so all strings are really in RAM
Hi @Siddharth-Velappan
The warmup time of the MH Z19b is 3 minutes. So 2 is probably fine, but you could probably do 3 just in case. Although 2 would save your more battery time.
Do you mind explaining your setup a bit more? I would love to do something similar but I do not know where to get started with the PIC microcontroller!

I had the contact with this seller, but an international money transfer was needed and is expensive...
yeah, they also have a minimum order quantity and ship with DHL only, so you have to pay import taxes to EU
so it only makes sense if you order a big quantitiy and then try to resell it somehow
all in all a hobby that at least has some return on investment, compared to other ones i had :))
You're courageous th have gone on kickstarter, from memory seeedstudio nearly went down because of an error on a crowdfunding project and had to produce and ship (the more expensive par of it) a remlacement for the first batches...
ahh .. i didnt know this about them... and in their scale - i can undertand
it happened to me as well but in my scale it was rather a paid lesson :))))
When you read the data sheet correctly you can see, that the distance between the pins is different for a AA and AAA battery holder. That`s why I was asking if somebody can recommend a holder that fits.
@vlad I am having the same issue. Where did you change keepalive timeout to a long time?
Essentially, what file did you edit, what parameter and to how long?
Hi all,
Should anyone face the same problem, I found the root cause: brownout threshold. I burned a new bootloader (Optiboot 8.0) without such trigger and the node has been working with used batteries (~2.7V) since May.
Hope this helps.
