I wonder if anyone can recommend me a free MQTT broker. I don’t want to install one on a raspberry pi (for example) in my house wasting electricity 24 hours, so a free cloud-based MQTT provider would fit my needs (only a few subscriptors)
Unfortunately, many hosted free MQTT brokers - that can be found on various lists on the Internet - no longer exist.
The only usable free broker I have found so far is flespi
