The Heishamon software on this PCB allows your smarthome to communicatie with the Panasonic Aquarea H-series and J-series heatpump replacing the original internet module. It provides MQTT messages for all known values and also provides 1wire DS18b20 and kWh S0 port power metering to provide a complete solution to monitoring the performance of the heatpump.

This PCB is necessary to communicatie with the heatpump. The software can be installed on every ESP8266 board but the communication to and from the heatpump requires some levelshifting. On this PCB the levelshifting is provided and also the connection for 1wire and S0 metering is on the PCB.

The PCB will be deliverd as shown on the photo and the latest HeishaMon software will be installed for you. You only need to hook it on to your Panasonic heatpump using the optional cable, configure it using the temporary open wifi hotspot and you can collect the MQTT data it transmits.
