I just bought a emonPI2 to replace an old emonPI unit I’ve being using for years.
The old emonPI had no problem with the three emonTH sensors I have.
The new emonPI2 can detect the oldest emonTH but doesn’t get updated data from it.
The newer emonTH v2 units are not detected at all.
All these items were bought directly from openenergymonitor
The rf node ids are 23 (old one), 25 and 26 (new ones)
I put new batteries in all and the light came on in each unit.
I’m not sure what to do next
Hi @rogeremon - do you know which version of the emonTH firmware you are using? Your probably need to upgrade to the latest emonTH firmware as the RF link protocol has changed to LPL from JeeLibs, which you likely have.
The newest was bought in 2020.
Do I need this thing to update it
Yes, you’ll need something like that. Given you are in NZ, it’s probably easier to source it locally - USB to serial converters are widely available.
I think this will be suitable – you might like to check with The Shop first
I updated the firmware but the emonTH2 is not detected.
There are lots of error messages in the log

Restarting EmonHub</details><br />```Hello @rogeremon could you share your emonhub.conf?
It should look like this: emonhub/conf/emonpi2.default.emonhub.conf at master · openenergymonitor/emonhub · GitHub
With an entry for the SPI (EmonHubRFM69LPLInterfacer) interfacer:

Aha, you want to select emonTH2_LPL as that uses the newer LowPowerLabs format which the emonPi2 uses. The emonPi2 does not support the older jeelib classic format
Thanks! All three units are working perfectly now.
