You can use this gateway too for Kamstrup Water Meters. They are all Kamstrup Multical 21 / FlowIQ water meters. Which are supported by the Kamstrup-IR gateway too.
nice that my experience was useful to someone 
here, the meters are changed by law every five years. I’m already thinking with a little worry if I have to go through the whole mess again.
Better late than never! Yes, I’m using this solution for my Multical 21 here in Estonia. Works great right out of the box and is very stable.
Any tips how to position the “Kamst-IR eye” on the water meter?
I have a flowIQ 2200 and a Kamst-IR all setup but I get no readings…
Any luck with that? Are you sure the “sending LED” is lined up with “receiving led” and vice versa?
Which Swedish municipality was that?
I asked mine (Trollhättan) and got the answer that this was no problem at all, we have a subscription service for that. Just EUR 20 per month! In addition to a one time fee.
20 per month for the key?! Or do you mean a cloudbased api?
For the key! I have asked them for a service description to be 100% sure. I’ll keep you posted.
That’s ridiculous. I would understand a one-time administration fee for providing the key, and maybe a fee for when you want to have it changed (which means they need to switch your meter to a different one), but a continuous monthly fee for something where they have zero effort once they handed you the key is completely unjustified.
That was Mjölby, and 20 EUR per month subscription is ridiculous as stated before!
Just cite the EU GDPR law… “Remember that those whose data you process (referred to as ‘the data subject’ in the GDPR), have the right to know exactly what data you are collecting about”
cheers
20 in month is ridiculous!
Still, citing GDPR here could be also trap to yourself - “Of course we give you all your data, you just need to give us 20 eur month for collecting and handling.”
Hej Anders. Undrar bara om du använder en iM871A-USB eller någon annan mottagare för att läsa av datan.
Hej
Jag använder någon billig RTL2838 DVB-T USB sticka som jag hade liggandes.
Adding a note here since this thread is mostly about Wireless M-Bus (wmbusmeters) — for anyone with a Multical 21 who’d rather use the optical IR port instead of Wireless M-Bus (no encryption keys to request from your utility, no RF adapter needed), there’s a HACS-listed integration that reads it via a cheap USB IR read/write head: mallewski/ha-multical_21. Config is fully UI-based, supports multiple meters, and just added a proper serial-port picker.
Might be a simpler path for people who don’t want to deal with radio decryption keys.
